The Alt SGPT blood analysis, also known as serum pyruvic glutaminase, is a medical diagnostic tool used to evaluate the health and function of the liver. The liver is a vital organ responsible for detoxification, nutrient storage and the production of important proteins. Understanding the implications of an abnormal result in an ALT blood analysis can provide valuable information on liver health.
What is the Alt SGPT blood analysis?
The Alt blood analysis measures the SGPT levels, an enzyme present in liver cells. When liver cells are damaged or inflamed, as in cases of disease or liver lesion, the SGPT is released to the bloodstream. Therefore, high levels of SGPT in a blood test may indicate liver damage or dysfunction. Alt’s blood analysis is usually done as part of a complete panel of the liver function, which includes other enzymes and liver markers to provide a more complete evaluation of liver health.
- Causes of high levels of SGPT:
- Hepatitis: The most common cause of high levels of SGPT is viral hepatitis.
- Alcohol consumption: excessive alcohol consumption can cause liver inflammation and increase in SGPT levels.
- Fatty liver disease: the accumulation of fat in the liver, known as no n-alcoholic fatty liver disease (NAFLD), can lead to high levels of SGPT.
Interpretation of the results of the Alt blood analysis:
SGPT levels are measured in units per liter (U/L). Normal ranges may vary slightly between laboratories, but usually, a healthy individual will have SGPT levels below 40 U/L for men and below 35 U/L for women. High levels of SGPT, often called SGPT elevation or lift of liver enzymes, should lead to a deeper investigation of the underlying cause. A healthcare professional will take into account the patient’s medical history, symptoms and other diagnostic tests to determine the appropriate course of action.
| Causes of high levels of SGPT | SGPT level (U/L) |
|---|---|
| Hepatitis | It varies, often increases significantly |
| Alcohol consumption | Elevated, it depends on the degree of liver damage |
| Fatty liver disease | Mild to moderately high |
