SGPT (Alanine Transaminase)

SGPT, also known as alanine transaminase (ALT), is an enzyme produced by the liver and has various functions. When the liver is damaged or inflamed due to certain medical conditions or lifestyle factors, it releases the enzyme ALT into the bloodstream. The SGPT or ALT test measures the level of this enzyme in your blood. Aside from the liver, ALT is also found in other body parts, such as the kidneys.

An SGPT test may be done if you experience symptoms such as loss of appetite, stomach pain, nausea, vomiting, itching, and the yellowing of the skin and eyes (symptoms of jaundice). This test may also help to monitor any ongoing liver disorders or evaluate the side effects of certain medicines affecting liver health and function; however, it does not tell the extent of liver damage. Usually, no special preparation is required for an SGPT test. You may eat and drink normally as per your daily routine.

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.
