Also known as: LFT, Liver Function Test, Fatty Liver, Jaundice
Understanding liver function tests — SGPT, SGOT, bilirubin, and what fatty liver really means.
How MedFast.AI helps with liver health reports
MedFast.AI reads your LFT report and explains each enzyme in context — SGPT vs SGOT, direct vs indirect bilirubin — with practical lifestyle guidance.
Tests & values you'll see
Click any term to open its plain-language explainer.
SGPT / ALT
An enzyme inside liver cells. Elevated levels mean the liver is stressed or inflamed — common causes are fatty liver, alcohol, or medications.
SGOT / AST
Another liver enzyme, also found in muscles and heart. Usually rises alongside SGPT/ALT when the liver is stressed.
Bilirubin
A yellow waste product the liver clears from your blood. High levels cause jaundice (yellow skin/eyes).
Albumin
The main protein in your blood, made by the liver. Low albumin suggests advanced liver disease, malnutrition, or kidney protein loss.
Total Protein
The sum of albumin + globulin in blood. Doctors use it to screen for liver, kidney, and immune problems.
GGT
A liver enzyme especially sensitive to alcohol use and bile-duct problems. Often rises before other liver enzymes in early damage.
Frequently asked questions
My SGPT is 65. Is that dangerous?
Mildly elevated (upper limit is usually 40–56 U/L for men). Very common in India due to fatty liver, alcohol, or medication. Not immediately dangerous, but your doctor will want to find and treat the cause before it progresses.
What is fatty liver and can it be reversed?
Fat deposits inside liver cells — extremely common in India (~30% of adults). Grade I and II are fully reversible with weight loss, better diet, reduced sugar/alcohol, and treating diabetes if present. Advanced stages can cause permanent damage, so don't ignore early findings.
My SGPT and SGOT are both high but bilirubin is normal. Should I worry?
This is a common pattern with fatty liver, medication effects, or viral hepatitis. Bilirubin only rises later when liver damage is more advanced. Your doctor will investigate the cause — usually with an ultrasound and viral serology.
