The Kidney #3 Extreme Blood and Urine Test Panel is done to evaluate the overall health of the kidneys. The kidneys are crucial in filtering waste and excess fluids from the blood, regulating blood pressure, and producing hormones that help control red blood cell production and bone health. A Kidney #3 Extreme Blood and Urine Test Panel is a comprehensive set of tests that provides a detailed evaluation of the overall health of the kidneys.

Complete Blood Count (CBC) With Differential and Platelets- measures various components of the blood, such as red blood cells, white blood cells, and platelets. An abnormal CBC result can indicate anemia, infection, inflammation, or other blood disorders affecting kidney function.

  • White Blood Cells (WBC)- The body's primary defense against disease and helps to fight infection.
  • Red Blood Cells (RBC)- Responsible for carrying oxygen and carbon dioxide away from all cells. Iron deficiency will lower the RBC count.
  • Hemoglobin- A chemical compound inside red cells that transports oxygen through the bloodstream to all body cells. Hemoglobin gives the red color to blood.
  • Hematocrit- Measures the amount of space red blood cells take up in the blood. It is reported as a percentage.
  • Neutrophils- Neutrophils are the most common type of white blood cells created by the bone marrow to combat various inflammatory and infectious diseases.
  • Lymphocytes- B-cells and T-cells are lymphocytes that fight bacteria and other pathogens in the blood. They are primarily found in the lymph system.
  • Monocytes- Working alongside neutrophils, monocytes play a vital role in fighting infections and other diseases and clearing away dead or damaged cells.
  • Eosinophils- White blood cells called eosinophils activate in response to allergies and certain infections.
  • Basophils-Basophils play a role in detecting infections early on, aiding in wound healing, and reacting to allergic responses.
  • Mean Corpuscular Hemoglobin (MCH)- The average hemoglobin concentration within a red blood cell.
  • Mean Corpuscular Hemoglobin Concentration (MCHC)- A red blood cell's average hemoglobin concentration percentage.
  • Mean Corpuscular Volume (MCV)- The average size of red blood cells.
  • Platelets- Blood cell particles associated with the forming of blood clots.
  • Red Cell Distribution Width (RDW)- Measures the amount of red blood cell variation in volume and size.
  • Absolute Neutrophils- The absolute neutrophil count measures the number of neutrophils in your blood. Normal range is 2,500-7,000 per microliter. Counts outside this range indicate a possible condition.
  • Absolute Lymphocytes-To calculate your absolute lymphocyte count, multiply your white blood cell count by the percentage of lymphocytes. This gives you the number of lymphocytes as an absolute number.
  • Absolute Monocytes-The absolute monocyte count indicates the number of monocytes in the blood, helping to identify if the count is normal, high, or low.
  • Absolute Eosinophils-Absolute eosinophil count measures the number of eosinophils in blood by multiplying the percentage of eosinophils in a complete blood count with the total number of white blood cells in the same count.
  • Absolute Basophils- Absolute basophil count is calculated by multiplying the percentage of basophils by the total number of white blood cells in a blood sample.

Comprehensive Metabolic Panel (CMP-14)- measures levels of various substances in the blood, such as electrolytes, glucose, and proteins. The kidneys play a key role in regulating these substances, and abnormal levels can be an early sign of kidney disease or other conditions that affect the kidneys.

  • Glucose- Blood sugar level is the most direct test to screen for diabetes and is also used in diabetes management.
  • Kidney Profile
    • Bun or Urea Nitrogen (BUN)- An indicator of kidney function.
    • Creatinine, Serum- An indicator of kidney function.
    • Bun/Creatinine Ratio- Calculated by dividing BUN by creatinine. This ratio can suggest conditions including dehydration or intestinal bleeding.
    • Estimated Glomerular Filtration Rate (eGFR)- Measures kidney function to determine kidney disease stage and detect early kidney damage.
  • Liver Panel
    • Protein, Total- Assists in determining liver and kidney function and nutritional health.
    • Albumin serum- One of the major proteins essential for the healthy function of the liver and kidneys.
    • Globulin, Total- One of the major proteins that assist the blood to clot properly and also comprises infection-fighting antibodies.
    • Albumin/Globulin Ratio- Calculated by dividing albumin by globulin. When paired with other test results, this ratio can assist in diagnosing various liver problems.
    • Bilirubin, Total- Aids in detecting hepatitis, sickle cell, anemia, cirrhosis, alcohol, and drug abuse. High concentrations may result in jaundice.
    • Alkaline Phosphatase- A protein vital in detecting bone disorders and liver disease.
    • Aspartate Aminotransferase (AST or SGOT)- An enzyme helpful in evaluating liver function. An elevated level is an indication of hepatitis.
    • Alanine Aminotransferase (ALT or SGPT)- An enzyme helpful in identifying liver damage. Abnormalities may represent liver disease.
  • Fluids & Electrolytes
    • Sodium- One of the major salts in body fluid. Sodium is essential in water balance and the electrical activity of nerves and muscles.
    • Potassium- Helps to control the nerves and muscles.
    • Chloride- Similar to sodium, it helps to maintain the body's electrolyte balance.
    • Carbon Dioxide, Total- Used to help detect, evaluate, and monitor electrolyte imbalances.
    • Calcium- A mineral essential for developing and maintaining healthy bones and teeth. It is also vital for the normal function of muscles, nerves, and blood clotting.

Urinalysis, Complete with a Microscopic Examination- measures various components of urine, such as protein, glucose, and red and white blood cells. An abnormal urinalysis result can indicate kidney disease, urinary tract infections, or other conditions that affect the kidneys.

  • Specific Gravity- The concentration of the urine sample. This is used to help evaluate the level of certain substances dissolved in the urine. Low specific gravity can result from ingesting large amounts of water before urination.
  • pH-This is affected by the acid/base balance in the body. A pH that is too high or low can form crystals in the urine, leading to the development of kidney stones. PH can be adjusted through diet or medication.
  • Color- Darker urine coloration can result from some medications, eating certain foods, blood in the urine, dehydration, or fever
  • Appearance- Bacteria, red blood cells, white blood cells, mucus, or contaminants such as lotions or powders may cause cloudy or turbid urine.
  • WBC Esterase- White blood cells in the urine typically indicate a bacterial urinary tract infection. It may also be caused by inflammation in the kidneys.
  • Protein- The amount of albumin in the urine. Protein in the urine can indicate kidney disease or conditions affecting the urinary tract.
  • Glucose- Glucose in the urine can be a sign of abnormally high blood sugar levels, such as those caused by diabetes.
  • Ketones- Ketones are produced when the body metabolizes fat. They can indicate several conditions, including starvation, a high protein/low carbohydrate diet, diabetes, or frequent vomiting.
  • Occult Blood- Blood in the urine can indicate several conditions affecting the kidneys or urinary tract. It can also be caused by contamination from sources such as menstruation, hemorrhoids, or vagin*l bleeding.
  • Bilirubin- Bilirubin is a waste product produced by the liver. Bilirubin in urine can be an early indicator of liver disease.
  • Urobilinogen- Urobilinogen is formed from Bilirubin. Its presence in urine is typically a sign of liver disease.
  • Nitrite- Nitrite in the urine is usually caused by bacteria, which can indicate a urinary tract infection.

Amicroscopic examinationwill automatically be performed if abnormalities are detected in the initial urinalysis. The microscopic examination may include some or all of the following if the results warrant:

  • White Blood Cells (WBCs)- WBCs in urine usually indicate inflammation or infection of the urinary tract.
  • Red Blood Cells (RBC)- RBCs in urine can be caused by inflammation, kidney injury, or urinary tract injury.
  • Epithelial Cells- High concentrations of epithelial cells are typically caused by infection or inflammation of the urinary tract.
  • Crystals- Crystals may be formed by various particles dissolved in urine. Crystal formation may be due to an abnormal pH balance or a higher-than-normal concentration of particles. Crystals formed in the kidneys may lead to the development of kidney stones.
  • Casts-Casts are cylindrical particles formed from proteins secreted by the kidneys. In people with kidney disease, substances such as RBCs or WBCs may become trapped in the proteins. Examining the casts can help differentiate between types of kidney disorders.
  • Mucus- Mucus in the urine may result from a urinary tract infection or conditions affecting the digestive system, specific STDs, or kidney disease.
  • Bacteria- Bacteria in the urine usually indicate a urinary tract infection. Care should be taken to avoid contaminating the specimen with bacteria from the genital area or hands.

Parathyroid Hormone (PTH) Intact -This test measures the parathyroid hormone level in the blood to detect hyperparathyroidism or to identify the reason behind abnormal calcium levels. The parathyroid glands, small glands located behind the thyroid gland, produce PTH that regulates calcium and phosphorous levels in the bloodstream. If the blood calcium level is low, the parathyroid glands release more PTH, causing the bones to release more calcium into the bloodstream and absorb more calcium and phosphorus by the intestines. Conversely, if the calcium level is high, the parathyroid glands release less PTH, and the process is reversed. Abnormal PTH levels can lead to kidney and bone problems and calcium and vitamin D changes. In addition to a PTH test, the blood's phosphorus and calcium levels can also be checked.

Vitamin D- A vitamin D test is used to detect bone malformation, bone weakness, or abnormal metabolism of calcium, which can occur due to a deficiency or excess of vitamin D. Individuals with diseases that hinder fat absorption, like cystic fibrosis and Crohn's disease, may be monitored with this test to ensure adequate amounts of vitamin D. The effectiveness of treatment involving vitamin D, calcium, phosphorus, and magnesium supplementation can also be determined with this test.

Creatine Kinase (CK) Blood Test, Total, Serum-CK levels are useful for detecting, evaluating, and monitoring muscle damage. When CK levels are elevated, it usually indicates that there has been some form of muscle damage, such as a heart attack, rapid muscle tissue breakdown, inflammation of muscles, muscular diseases like muscular dystrophy, and other similar conditions. Therefore, monitoring CK levels can be an effective way to assess and diagnose certain health conditions.

Phosphorus- Phosphorus level testing is a diagnostic procedure that can determine if the levels of phosphorus in the body are above or below the expected range. This is important because such anomalies can point to a variety of differential diagnoses, such as dehydration, renal disease, liver disease, and diabetic ketoacidosis. Healthcare professionals can identify the underlying cause of the patient's health condition by measuring the phosphorus levels and thus recommend appropriate treatment options.

Protein electrophoresis (SPE)- Protein electrophoresis (SPE) is a laboratory test that separates and measures the different types of proteins in a blood sample. It is a sensitive and specific tool for detecting and evaluating various medical conditions. SPE can help identify the presence of monoclonal proteins produced by abnormal cells in the immune system and can indicate serious disorders such as multiple myeloma. It can also be used to diagnose liver disease, inflammation, and immune system disorders like hypogammaglobulinemia. By analyzing the pattern of proteins, doctors can gain valuable insights into a patient's health status and make informed decisions about their care.

Protein/creatinine ratio- Testing a first-morning or random untimed "spot" urine specimen is recommended to diagnose chronic kidney disease as well as evaluate other renal diseases such as nephrotic syndromes, glomerulonephritis, and toxemia of pregnancy. It is also used to manage myeloma and macroglobulinemia of Waldenstrom and evaluate hypoproteinemia, tubular proteinurias, and drug nephrotoxicity. Urinary albumin (microalbumin) is a more sensitive marker of the progression and regression of renal disease than urine total protein, especially when urine total protein is less than 300 mg/g creatinine.

Microalbumin random urine- The test aims to identify the presence of the protein albumin in urine, which is typically absent in individuals with normal kidney function. However, even small amounts of albumin can be detected in the urine when the kidneys are damaged or diseased. This test is an effective diagnostic tool for determining kidney damage or disease, as the presence of albumin in urine can indicate the early stages of kidney problems. By detecting albumin in urine early, patients can receive timely treatment to prevent the progression of kidney disease and avoid complications associated with advanced kidney damage.

By combining these tests, healthcare providers can get a comprehensive and detailed picture of a patient's kidney health. Early detection of kidney disease is crucial for effective treatment, and a Kidney #3 Extreme Blood and Urine Test Panel can help identify any potential issues before they become more serious.

Which lab is most indicative of kidney damage? ›

CKD is evaluated using two simple tests – a blood test known as the estimated glomerular filtration rate (eGFR) and a urine test known as the urine albumin-creatinine ratio (uACR). Both tests are needed to have a clear picture of your kidney health.

What labs are included in a renal function panel? ›

Evaluate for kidney dysfunction in patients with known risk factors (eg, hypertension, diabetes, obesity, family history of kidney disease). Panel includes albumin, calcium, carbon dioxide, creatinine, chloride, glucose, phosphorous, potassium, sodium, and BUN and a calculated anion gap value.

What is the test for stage 3 kidney disease? ›

Stage 3 CKD is diagnosed based on estimated glomerular filtration rate (eGFR) readings. This is a blood test that measures creatine levels. An eGFR test is used to determine how well your kidneys are working at filtering wastes.

What is the golden test for kidney function? ›

Glomerular filtration rate (GFR) has long been considered the best overall index of kidney function in health and disease.

Can a blood test detect bad kidneys? ›

Because your kidneys remove waste, toxins, and extra fluid from the blood, a doctor will also use a blood test to check your kidney function. The blood tests will show how well your kidneys are doing their job and how quickly the waste is being removed. Here are a few blood tests that are used: Serum creatinine.

What lab results indicate kidney disease? ›

Estimated glomerular filtration rate (eGFR)

A “normal” eGFR varies according to age – it decreases as you get older. For this test, a higher number is better. In general, an eGFR value lower than 60 is a sign that the kidneys may not be working properly. An eGFR lower than 15 is a marker of kidney failure.

How do you treat stage 3 kidney disease? ›

The more impactful symptoms of kidney disease stage 3 are the health implications of your decreased kidney functioning such as high blood pressure, anemia, and bone disease. If your kidneys fail, you will either need to have dialysis or a kidney transplant. Dialysis is a treatment that will clean your blood.

What color is your pee if you have kidney disease? ›

Some liver and kidney disorders and some urinary tract infections can turn urine dark brown. So can bleeding inside the body called a hemorrhage. A group of illnesses that mainly affect the skin or the nervous system, called porphyria, also can cause brown urine.

What level of creatinine is alarming? ›

High creatinine levels can indicate a range of underlying health conditions, including kidney infection and kidney failure. Doctors typically consider high creatinine levels to be above 1.2 milligrams per deciliter (mg/dL) for males and 1.0 mg/dL for females. Creatinine is a waste product of the muscles.

What color is urine when your kidneys are failing? ›

If your kidneys are failing, they may retain fluids, and harmful waste can build up in your body. If this happens, your urine may include excess protein, toxins, and blood. This can cause your urine to change color, becoming a darker tan, brown, or even slightly red.

What is the most accurate test for kidney function? ›

Serum creatinine test

Healthy kidneys filter creatinine out of your blood through your urine. Your serum creatinine level is based on a blood test that measures the amount of creatinine in your blood. It tells how well your kidneys are working.

Do I need to fast for a renal function panel blood test? ›

Patient should fast overnight (12 hours preferred; eight hours acceptable) preceding collection of specimen.

Is a renal function panel blood or urine test? ›

Kidney function tests measure how efficiently your kidneys are working. Most of these tests check how well your kidneys clear waste from your system. A kidney test may involve a blood test, 24-hour urine sample or both. You usually have your test results the same day or within a few days.

What is the most common test for renal function? ›

Clinically, the most practical tests to assess renal function is to get an estimate of the glomerular filtration rate (GFR) and to check for proteinuria (albuminuria). The best overall indicator of the glomerular function is the glomerular filtration rate (GFR).

What are the diagnostics for kidney function? ›

The main test for kidney disease is a blood test. The test measures the levels of a waste product called creatinine in your blood. A doctor uses your blood test results, plus your age, size, and gender to calculate how many millilitres of waste your kidneys should be able to filter in a minute.

What is the new kidney function test? ›

A cystatin C blood test can be useful if: A past test for kidney function did not give clear results about your kidneys, so your healthcare provider wants to check again with a cystatin C test to be sure. You are older or have lots of muscle (such as a bodybuilder), where creatinine levels can vary.
