1) What is LFT? (Liver Function Test)
LFT stands for Liver Function Test — a group of blood tests that help doctors check how well your liver is working. These tests measure different substances produced by or processed in the liver, such as enzymes, proteins, and bilirubin. Elevated levels of certain enzymes may indicate liver inflammation, damage, or disease like hepatitis, fatty liver, or cirrhosis. LFTs are useful not only for diagnosis but also to monitor treatment progress and detect damage early.
Why LFT is important?
- Detects liver inflammation or damage
- Helps diagnose hepatitis, fatty liver, cirrhosis
- Monitors liver health over time
- Checks for effects of medications that can harm the liver
Common LFT Parameters
-
ALT & AST: Liver enzymes released when liver cells are injured
-
Bilirubin: Waste product processed by liver
-
Albumin: Protein made by liver
-
ALP & GGT: Other enzymes indicating liver or bile duct issues
2) What is KFT? (Kidney Function Test)
KFT stands for Kidney Function Test — a series of blood (and sometimes urine) tests to evaluate how well your kidneys are filtering waste from your blood and maintaining fluid balance. Healthy kidneys remove waste products like urea and creatinine; abnormal levels can signal kidney dysfunction.
Why KFT is important?
-
Detects early signs of kidney disease
-
Helps monitor kidney function in chronic conditions like diabetes or high blood pressure
-
Evaluates effectiveness of treatment for kidney issues
Common KFT Components
-
Creatinine: Waste filtered by kidneys
-
Urea (BUN): Waste product from protein breakdown
-
GFR (Glomerular Filtration Rate): Best indicator of kidney filtering ability
-
Electrolytes: Sodium, potassium, calcium levels help assess balance and overall function
When Should You Do KFT and LFT?
Doctors often recommend these tests:
- During routine health checkups.
- If you have symptoms like fatigue, swelling, jaundice (yellowing of eyes/skin), changes in urine.
- If you have risk factors such as diabetes, hypertension, or long-term medication use.
- To monitor known liver or kidney conditions.
