Hepatogram

What is a Hepatogram?

Patients often receive a referral from their doctor to have a hepatogram and then ask us what it is, as the term “hepatogram” may not be listed in the price catalog of tests. A hepatogram is a group of tests used to assess the condition and function of the liver. This group of tests is named based on the organ being evaluated (hepato – comes from the Greek word for liver).

What Tests Are Included in a Hepatogram?

A hepatogram includes tests for liver enzymes and bilirubin:

1. ALP (Alkaline Phosphatase)
2. ALT (SGPT, Alanine Aminotransferase)
3. AST (SGOT, Aspartate Aminotransferase)
4. GGT (Gamma-Glutamyl Transferase)
5. Total Bilirubin

Why is a Hepatogram Performed?

When liver cells (hepatocytes) are damaged, liver enzymes are released into the blood, causing their concentration in the blood to increase. Elevated levels of alkaline phosphatase and total bilirubin are often due to obstruction of the liver and bile ducts. Causes can vary, with some being transient, such as the use of certain medications, prolonged alcohol consumption, and viral infections. Impaired liver function can also be due to serious conditions, such as liver cirrhosis and malignancies.

Special Patient Preparation

No special preparation is required, but it is preferable to take the sample in the morning before eating (“fasting”).
