Liver health blood tests, at home

No fasting required for an LFT alone. If you're combining with a lipid profile or fasting blood sugar, then 8–12 hours of fasting is needed. Avoid alcohol for at least 24 hours before to avoid temporary enzyme elevation.

Mildly elevated SGPT (40–80 IU/L) is often due to fatty liver, recent alcohol or some medications. Persistent elevation needs further evaluation — ultrasound, hepatitis serology and clinical assessment. Always interpret values with a clinician.

LFT screens for it (often SGPT > SGOT). An ultrasound of the abdomen confirms it. There is no specific blood test that says "you have fatty liver" — the diagnosis is clinical. Treatment is weight loss, exercise and diabetes control.

Yes at least once as an adult — India has a 2–4% chronic hepatitis B prevalence. If positive, you may need antiviral treatment to prevent liver damage. Vaccination is also available for those who have never had hepatitis B and are negative.

Yes. A single binge can elevate SGPT, SGOT and GGT for several days. Stop alcohol for at least 24–48 hours before the test for a reliable baseline. GGT in particular is sensitive to recent drinking.
