Alanine Transaminase (SGPT) is part of liver assessment. It helps detect inflammation, fatty liver, hepatitis and other conditions, often before symptoms appear.
Alanine Transaminase (SGPT/ALT) is an enzyme found almost exclusively in the liver. It’s the most liver-specific marker in the standard Liver Function Test panel and is usually the first value doctors check when investigating possible liver damage.
Why is the Alanine Transaminase (SGPT) done?
Ordered as part of liver function testing, to investigate symptoms of liver damage, and to monitor known liver conditions.
It can help your doctor assess
Liver cell damage from viral hepatitis, fatty liver disease, alcohol use, or drug-induced liver injury.
Who may need this test?
This test may be considered for:
Anyone undergoing liver function testing
Regular alcohol drinkers
People with risk factors for fatty liver disease
Those on medicines that can affect the liver.
Whether this test is right for you depends on your symptoms, medical history and the reason for testing - your doctor can advise.
What does this test measure?
The concentration of ALT enzyme in the blood.
SGPT/ALT
Liver Enzyme
The most liver-specific of the standard LFT enzymes - a raised ALT is a reliable signal of liver-cell inflammation or damage.
Understanding your Alanine Transaminase (SGPT) results
How to read your result
Your report should be read using the reference interval, unit and method shown by the performing laboratory. A result outside a reference interval does not automatically establish a diagnosis, and a result inside the interval does not rule out every health problem. Clinical interpretation depends on symptoms, history and other findings.
Marker
Result
What it may be associated with
SGPT/ALT
High
A reliable marker of liver-cell damage - common causes include fatty liver, viral hepatitis, alcohol use, or certain medicines.
If a result is outside the range
If the Alanine Transaminase (SGPT) is reported as high, low, positive, negative or otherwise outside the laboratory's stated interval, the meaning depends on the specific test and the reason it was ordered. Your clinician may consider repeat testing, related investigations or other clinical information before deciding what the result means.
Limitations of this test
A raised ALT signals liver-cell stress but not the specific cause - further tests (viral hepatitis panel, ultrasound) are often needed to pinpoint it.
An abnormal result does not by itself mean you have a particular disease. Your doctor interprets results together with your symptoms, history and other tests.

How should I prepare for the Alanine Transaminase (SGPT)?
No fasting is needed - you can eat and drink normally.
Drink water as usual - being well hydrated makes the blood draw easier.
Tell the collection team about any medicines and supplements you take.
Do not stop prescribed medicines unless your doctor tells you to.

Laboratory processing
Your sample is processed in our laboratory and reviewed by a pathologist.
05
Report
Your report is shared on WhatsApp and email, usually within 24 hours.
For a blood-based test, a small blood sample is collected by a trained healthcare professional, usually from a vein in the arm. The collection normally takes only a few minutes; mild temporary discomfort or bruising can occur at the puncture site.
What can affect the result?
Alcohol in the past 24-48 hours and certain medicines can raise ALT without indicating chronic disease.
When should you talk to a doctor?
Laboratory results are interpreted together with your symptoms, medical history and other investigations. If your results are significantly abnormal, or you have symptoms that worry you, discuss them with a qualified doctor promptly.
