How to check liver function at home?

At-home alternatives (limited utility): Some services offer home phlebotomy — a trained technician visits and collects blood for LFTs which are then processed by a lab. That gives accurate results without you going to a clinic. Search for accredited diagnostic providers in your city that offer home sample collection.

Short, responsible answer: You cannot perform a medically reliable full liver function test at home. Liver function is assessed with blood tests (LFTs) — AST, ALT, ALP, bilirubin, albumin, and others — done at a diagnostic lab. What you can do at home (screening / red flags): - Watch for symptoms: jaundice (yellowing of eyes/skin), persistent fatigue, dark urine, pale stools, abdominal pain or swelling. - Avoid alcohol, hepatotoxic drugs, and follow a healthy diet. - If symptoms or risk factors exist (hepatitis exposure, medications, fatty liver risk), see a doctor for formal blood tests and ultrasound.
