Decoding Your Liver Function Test (LFT)
Your blood report is a window into your liver's health. Let's learn how to look through it.
What is an LFT, anyway?
I often tell my patients in Bangalore that the liver is like a massive chemical factory. It processes everything you eat, drink, or breathe. A Liver Function Test (LFT) doesn't actually measure "how well" the liver is working in one single number; rather, it measures different proteins and enzymes that leak into your blood when the factory is under stress.

Have a concerning report?

The "Big Five" Markers Explained
Here is a breakdown of the terms you see on your pathology report, translated into plain English.
| Test Name | What it actually is | High levels might mean... |
|---|---|---|
| Bilirubin | A yellow pigment from old blood cells. | Jaundice, bile duct blockage, or liver inflammation. |
| SGPT (ALT) | An enzyme found mostly inside liver cells. | Liver cell damage (Fatty liver, Hepatitis). |
| SGOT (AST) | An enzyme found in liver, heart, and muscles. | Liver stress, or sometimes muscle/heart issues. |
| Alkaline Phosphatase (ALP) | An enzyme related to bile ducts and bones. | Bile duct obstruction or bone-related growth. |
| Albumin | A protein the liver makes to keep fluid in blood. | Low levels suggest chronic liver damage. |
Common Myth: "My SGPT is high, I have Cirrhosis!"
The Reality: An elevated SGPT (ALT) is very common in Bangalore due to fatty liver (MASLD). It means your liver cells are currently "irritated," but it does not mean your liver is scarred (Cirrhosis). Most mild elevations can be reversed with the right diet and exercise—habits I hand-hold my patients through every day.
Dr. Srinivas’s Golden Rules for a Healthy LFT
If your report shows mild abnormalities, don't just search the internet for "liver cleanses." Follow these medically-sound steps instead:
- Weight Matters: A 5% drop in body weight can drastically lower your SGPT levels.
- The 30-Minute Walk: Physical activity helps the liver process fats more efficiently.
- Avoid "Hidden" Hepatotoxins: Be wary of self-medicating with "herbal" supplements or heavy painkillers (like excessive Paracetamol), as these can cause "drug-induced liver injury."
- Water vs. Alcohol: Alcohol is a direct toxin. Hydration with water helps the liver flush out metabolic waste.
When to See a Specialist:
If your Bilirubin is above 2.0, or if your Albumin is dropping, these are signs that your liver is struggling to keep up. I recommend a consultation at Kauvery Hospital or Dhaara Speciality if your LFT remains abnormal for more than 3 months despite lifestyle changes.
