SGPT (Alanine Transaminase)

SGPT, also known as alanine aminotransferase (ALT), is an enzyme involved in amino-acid metabolism. It is found predominantly in the liver, with smaller amounts present in other tissues, including the kidneys, heart, and skeletal muscles. When liver cells are damaged or inflamed, ALT can be released into the bloodstream, causing its blood level to increase. Therefore, the SGPT or ALT test is commonly used to assess possible liver cell injury.

An SGPT test may be performed if you experience symptoms or clinical findings that may suggest liver disease, such as loss of appetite, abdominal pain, nausea, vomiting, itching, dark-coloured urine, or yellowing of the skin and eyes (jaundice). It may also be used to monitor changes in ALT levels in people with known liver conditions or during follow-up, and to assess possible liver effects of certain medicines. However, an ALT test alone cannot determine the cause or extent of liver damage. Usually, no special preparation is required for an SGPT test when performed alone. Eat and drink as per your usual routine unless your doctor or laboratory provides specific instructions.

Test result ranges are approximate and may differ slightly between labs depending on the methodology and laboratory guidelines. Talk to your doctor about your specific test results. Narrate your complete medical history to help the doctor correlate your clinical and laboratory findings. The test results will help them determine your medical condition, make recommendations for lifestyle modifications such as diet and exercise, decide whether or not medication will be required to manage your liver health, and formulate your overall treatment plan.
