ALANINE AMINO TRANSFERASE (ALT / SGPT)

The #1 Indicator of Liver Health

The SGPT (Serum Glutamic Pyruvic Transaminase) test, now more commonly known as ALT (Alanine Aminotransferase), is a blood test that checks for liver damage.

Think of SGPT/ALT as a "Leak Detector." This enzyme normally lives inside your liver cells, helping your body break down food. However, if your liver cells are damaged or inflamed, they "leak" this enzyme into your bloodstream. Therefore, high levels in your blood are a direct sign of liver stress or injury.

 Tthe liver is a silent organ, damage often occurs without pain. Doctors order this test to:

• Screen for Hepatitis: It is a primary marker for Hepatitis A, B, and C.
• Monitor Alcohol Impact: Regular heavy drinking damages liver cells, causing SGPT to spike.
• Check for Fatty Liver: Non-Alcoholic Fatty Liver Disease (NAFLD) is a leading cause of mild SGPT elevation.
• Monitor Medication Safety: Certain medications (like statins for cholesterol, or long-term antibiotics) can stress the liver. This test ensures your medication isn't harming you.
• Investigate Symptoms: If you have jaundice (yellow eyes/skin), dark urine, nausea, or abdominal swelling.
