Liver Profile Test



The liver profile test, also known as the liver function test (LFT), is a blood test that measures the levels of various enzymes and proteins in the blood that are produced by the liver. This test is used to evaluate the overall health and function of the liver, as well as to detect and monitor liver disease or damage.

The liver profile test typically includes measurements of the following:

Alanine aminotransferase (ALT) and aspartate aminotransferase (AST): These are enzymes produced by liver cells that are released into the blood when liver cells are damaged. Elevated levels of these enzymes can indicate liver damage.

Alkaline phosphatase (ALP): This is an enzyme that is found in many tissues throughout the body, including the liver. Elevated levels of ALP can indicate liver or bone disease.

Gamma-glutamyl transferase (GGT): This is an enzyme that is produced by the liver and other organs. Elevated levels of GGT can indicate liver disease or alcohol abuse.

Total protein and albumin: These are proteins produced by the liver that help maintain fluid balance in the body. Abnormal levels of these proteins can indicate liver disease or other health conditions.

Bilirubin: This is a pigment produced by the liver that helps to break down old red blood cells. Elevated levels of bilirubin can indicate liver disease or other health conditions.

The liver profile test is typically ordered by a healthcare provider if a patient has symptoms of liver disease, such as jaundice, fatigue, or abdominal pain, or if a patient has risk factors for liver disease, such as a history of alcohol abuse or viral hepatitis. The test may also be ordered as part of a routine check-up or to monitor the effects of certain medications or treatments on the liver.

Renal Function Test

A kidney function test, also known as a renal function test, is a medical examination that measures how well your kidneys are functioning. There are several different tests that can be performed to assess kidney function, including: Blood urea nitrogen (BUN) test: This test measures the amount of urea nitrogen in your blood. Urea is a waste product that is created when your body breaks down proteins. If your kidneys are not functioning properly, the level of urea nitrogen in your blood can rise. Serum creatinine test: This test measures the level of creatinine in your blood. Creatinine is a waste product that is created when your muscles use energy. The kidneys filter creatinine out of your blood and excrete it in your urine. If your kidneys are not functioning properly, the level of creatinine in your blood can rise. Glomerular filtration rate (GFR) test: This test measures how much blood your kidneys filter per minute. A GFR below 60 mL/min/1.73 m² may indicate kidney dis

CBC TEST

The CBC test, also known as a Complete Blood Count test, is a common blood test that measures various components of your blood. This test is typically done as a part of a routine health check-up or if your doctor suspects that you may have a medical condition that affects your blood cells. The CBC test measures several components of your blood, including: Red blood cells (RBCs): This measures the number of red blood cells in your blood. Red blood cells are responsible for carrying oxygen throughout your body. White blood cells (WBCs): This measures the number of white blood cells in your blood. White blood cells are a vital component of your immune system and help fight infections. Hemoglobin (Hb): This measures the amount of hemoglobin in your blood. Hemoglobin is a protein in your red blood cells that carries oxygen from your lungs to the rest of your body. Hematocrit (Hct): This measures the proportion of red blood cells in your blood. Platelets: This measures the number
