SGPT (Alanine Aminotransferase, ALT) Test
The SGPT Test, also known as the Alanine Aminotransferase (ALT) Test, measures the level of the ALT enzyme in your blood. ALT is primarily found in the liver, and elevated levels may indicate liver damage or disease. At Hindustan Laboratory, we provide accurate SGPT testing to assess liver health and support early diagnosis.
What is an SGPT (ALT) Test?
The SGPT test quantifies the amount of ALT enzyme in a blood sample. ALT is released into the bloodstream when liver cells are damaged, making it a key marker for detecting liver conditions such as hepatitis or fatty liver disease. The test is often performed alongside other liver function tests, such as SGOT (AST), for a comprehensive assessment.
Purpose of the SGPT Test
- Diagnose liver diseases, such as hepatitis, cirrhosis, or non-alcoholic fatty liver disease.
- Monitor liver function in patients with known liver conditions or risk factors like obesity or alcohol use.
- Evaluate the effects of medications or treatments that may affect the liver.
- Assess symptoms like jaundice, abdominal pain, or fatigue that may indicate liver issues.
- Support routine health checkups, especially for patients with liver disease risk factors.

Preparation for the SGPT Test
Minimal preparation is typically required for an SGPT test. However, consider these guidelines:
- Inform your doctor about medications (e.g., statins, antibiotics, or painkillers) or supplements, as they may affect ALT levels.
- Avoid alcohol consumption before the test, as it can elevate ALT levels.
- Fasting is usually not required, but follow any specific instructions provided by Hindustan Laboratory (e.g., fasting for combined liver function tests).
- Notify our team of recent conditions like liver-related symptoms or viral infections, which may influence results.
Procedure
The SGPT test is a simple and quick blood test:
- A healthcare professional cleans the site (usually your arm) with an antiseptic.
- A needle is inserted into a vein to collect a small blood sample.
- The sample is sent to our advanced laboratory, where ALT levels are measured using automated analyzers.
- The procedure takes less than 5 minutes and involves minimal discomfort.
Interpreting SGPT Test Results
Your SGPT (ALT) results are compared to standard reference ranges. Abnormal results may indicate:
- High ALT Levels:
- Causes: Liver damage (e.g., hepatitis, cirrhosis, fatty liver), alcohol abuse, viral infections, certain medications, or obesity.
- Symptoms: Jaundice, fatigue, abdominal pain, nausea, or swelling, depending on the underlying condition.
- Low ALT Levels:
- Causes: Typically not clinically significant; may occur in healthy individuals or with vitamin B6 deficiency.
- Symptoms: Usually none.
ALT is often interpreted alongside SGOT (AST) and other liver function tests. A high ALT/AST ratio may suggest liver-specific damage, while a low ratio may indicate other organ involvement (e.g., heart). Always consult your doctor for a detailed interpretation, considering your medical history, symptoms, and other test results.
