LFT stands for Liver Function Test and assesses the health of your liver. RFT, on the other hand, stands for Renal Function Test (also known as Kidney Function Test), which evaluates the function and health of your kidneys.
Both LFT and RFT are groups of tests that involve measuring the levels of various substances in your blood. These tests can help identify various issues, such as:
-
LFT can detect problems with liver function, such as damage or infection. Some of the common tests involved in LFT are:
- AST (Aspartate aminotransferase): A high AST level might indicate a problem with the liver or muscles.
- ALT (Alanine aminotransferase): This is a more specific marker for liver damage than AST.
- ALP (Alkaline phosphatase): High levels of ALP can be indicative of liver problems, bone disorders, or other conditions.
- Total bilirubin: This test measures the amount of bilirubin in your blood, a pigment produced by the breakdown of red blood cells.
- Albumin: This protein is produced by the liver, and low levels can indicate liver damage.
-
RFT can detect problems with kidney function, such as damage, infection, or blockage. Common tests included in RFT are:
- Creatinine: This waste product is filtered out by the kidneys. High levels of creatinine in the blood can indicate kidney dysfunction.
- Blood Urea Nitrogen (BUN): Another waste product that is filtered out by the kidneys. Elevated BUN levels might point to kidney problems.
- Glomerular Filtration Rate (GFR): This measures the rate at which your kidneys are filtering waste products from your blood. A low GFR signifies reduced kidney function.
These tests are often ordered by doctors to diagnose or monitor various health conditions. They are also used to check for kidney or liver damage caused by certain medications or other factors.
It is important to note that these tests only provide a snapshot of your liver or kidney function at a particular time. It is crucial to consult with your doctor to discuss the results of your tests and get a proper diagnosis.
