What is a Liver Function Test(LFT) Test in Visit Clinic?

Liver function tests measure enzymes, bilirubin, and proteins that tell how well the liver works. Common measures include ALT, AST, ALP, GGT, bilirubin, albumin, and total protein. The liver processes nutrients, makes important proteins, removes toxins, and produces bile for digestion. Abnormal results can suggest hepatitis, nonalcoholic fatty liver disease, cirrhosis, bile duct blockage, alcohol or drug-related injury, or hemolysis. Doctors order LFTs for routine health checks, when patients have jaundice, abdominal pain, dark urine, or unexplained fatigue. They also use them to monitor known liver disease and to check safety before surgery or when starting medicines that affect the liver. Patterns of test changes guide further tests and treatment.

  • total and direct bilirubin
  • albumin
  • total protein
  • prothrombin time/INR

Why Take a Liver Function Test(LFT) Test in Visit Clinic?

The Liver Function Test panel is a common blood profile used when doctors suspect liver disease, during routine health checks, or before starting medicines that can affect the liver. Symptoms like jaundice, abdominal pain, dark urine, or unexplained fatigue often prompt testing. Abnormal results can come from infections, fatty liver, alcohol or drug damage, blockages, or other illnesses and medications. A family history of liver disease also makes testing important.

What is LFT in liver function test in Visit Clinic?plus

LFT stands for liver function tests, a panel of blood tests measuring liver enzymes (ALT, AST, ALP, GGT), bilirubin, albumin and clotting (prothrombin time). They assess liver cell injury, bile flow and the liver’s synthetic ability. LFTs help diagnose, stage and monitor liver disease or medication effects; abnormal results require clinical correlation and further evaluation.

What is a normal LFT level in Visit Clinic?plus

A normal liver function panel includes typical reference ranges: ALT 7–56 U/L, AST 10–40 U/L, alkaline phosphatase 44–147 U/L, gamma‑GT about 9–48 U/L, total bilirubin 0.1–1.2 mg/dL, and albumin 3.5–5.0 g/dL. Prothrombin time/INR is usually about 11–13.5 seconds (INR 0.8–1.2). Ranges vary by lab, age, sex and clinical context—interpret with your clinician.

What is a liver function test in pregnancy in Visit Clinic?plus

A liver function test in pregnancy is a blood panel measuring enzymes and proteins — typically ALT, AST, alkaline phosphatase, GGT, bilirubin and albumin — to assess maternal liver health. It detects pregnancy-related problems (intrahepatic cholestasis, preeclampsia/HELLP) and other liver disease. Results are interpreted with normal pregnancy-related changes in mind; testing is done for symptoms or risk factors.

What are four warning signs of a damaged liver in Visit Clinic?plus

Four warning signs of liver damage are: 1) Jaundice — yellowing of the skin and eyes; 2) Persistent abdominal pain or swelling, especially in the upper right side or with fluid buildup; 3) Unexplained fatigue, weakness, or confusion; 4) Easy bruising or bleeding, and changes in urine/stool color (dark urine, pale stools) indicating impaired bile processing.

What is a bad LFT result in Visit Clinic?plus

A bad LFT result shows abnormal liver enzyme or function markers: significantly raised ALT and AST (hepatocellular injury), high ALP and GGT (cholestasis), elevated bilirubin (jaundice risk), low albumin and prolonged prothrombin time (reduced synthetic function). Severity depends on how far values deviate, their pattern and trends; marked or worsening abnormalities warrant urgent clinical assessment to identify causes and guide treatment.

Is LFT need fasting in Visit Clinic?plus

Most liver function tests (ALT, AST, ALP, GGT, bilirubin, albumin) do not require fasting. However, labs may ask for an 8–12 hour fast if LFTs are ordered alongside lipid or glucose tests or if your clinician requests it. Avoid alcohol for 24–48 hours beforehand and tell staff about medications and supplements, as these can affect results.
