Liver Function Test(LFT)

Liver Function Test(LFT) is used to measures liver enzyme levels to detect liver damage, hepatitis, or fatty liver disease. It is clinically indicated for people with jaundice, dark urine, persistent fatigue, abdominal pain, or history of hepatitis or alcohol use. GetVisit provides access to this test with transparent pricing, NABL-accredited labs, and cashless OPD from major insurers.
What is a Liver Function Test(LFT) Test in Noida ?
What is Liver Function Test(LFT)?
Liver Function Test(LFT) is a liver function test that evaluates the health of the liver by measuring the level of specific enzymes or proteins in the blood. The liver plays a central role in filtering toxins, producing bile for digestion, metabolising drugs, and synthesising proteins. When liver cells are damaged, they release enzymes into the bloodstream that can be detected and quantified through this test.
What does Liver Function Test(LFT) measure?
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. The degree of enzyme elevation correlates roughly with the severity of liver injury: mild elevations (2 to 3 times the upper limit of normal) typically suggest early or reversible changes; elevations above 10 times normal indicate significant acute liver injury. The test processes a standard blood sample through NABL-accredited laboratory equipment, with results typically available on the same day.
What do the results of Liver Function Test(LFT) mean?
Results are reported in units per litre (U/L) or milligrams per decilitre (mg/dL) alongside the laboratory's reference range. A value within the reference range indicates the liver is functioning normally. Mild elevations (up to 3 times the upper limit of normal) often indicate reversible changes such as fatty liver or medication effect. Moderate to severe elevations (above 5 to 10 times normal) suggest significant liver cell injury and require urgent clinical review, including imaging and additional blood tests.
Liver Function Test(LFT) Test Preparation in Noida
Fasting and dietary instructions:
Do not eat or drink anything except plain water for 8 to 12 hours before the test. Drinking water freely is encouraged , it keeps you hydrated and makes venipuncture easier. Avoid tea, coffee, juice, milk, and chewing gum during the fasting window even if they are taken without sugar.
Medication guidance:
Continue taking all regular prescribed medication unless your doctor has specifically asked you to stop before this test. Inform the lab staff about all medications, supplements, and herbal remedies you are currently taking. Some substances affect specific test values, and this information helps your doctor interpret results accurately.
What to bring:
Carry your doctor's test order, a photo ID, and your corporate OPD insurance card to the appointment. If you have had this test done before, bring your previous reports , comparing values over time is clinically more meaningful than interpreting a single reading in isolation.
Timing:
The best time for blood tests is in the morning after an overnight fast and a night of normal rest. Stress, poor sleep, and strenuous activity can affect several hormonal and metabolic markers. Booking a morning slot minimises these variables.

Why Take a Liver Function Test(LFT) Test in Noida ?
When does a doctor order Liver Function Test(LFT)?
Gastroenterologists order Liver Function Test(LFT) when liver disease is suspected based on symptoms, physical examination, or abnormal findings on a previous blood test. Common triggers include new-onset jaundice, a diagnosis of hepatitis B or C, metabolic syndrome, heavy alcohol use, or elevated liver enzymes found incidentally during a health check-up. It is also ordered at regular intervals to monitor patients already on treatment for liver disease.
Who should get Liver Function Test(LFT) done?
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. Regular liver enzyme testing is especially valuable for people with fatty liver disease (NAFLD or NASH), patients recovering from hepatitis, those in recovery from heavy alcohol use, and anyone with unexplained prolonged fatigue, nausea, or abdominal discomfort that has not yet been investigated. Early detection of rising enzyme levels allows doctors to intervene before significant, irreversible damage accumulates.
What happens after the results are ready?
Your doctor will interpret the results in the context of your symptoms, medical history, and risk factors. Results outside the normal range do not automatically indicate disease , they are a signal that requires clinical interpretation. GetVisit's digital report is saved to your health timeline and remains accessible and shareable at any time, making follow-up consultations more efficient.
