The most specific indication in case of cirrhosis of liver cells is the increase in the level of which enzyme?

biology human health and disease drug, tobacco and alcohol consumption addiction and dependence community health and hygiene

  1. CoA

  2. SGPT

  3. LDH

  4. CPK

Show answer
Correct Option: B
Explanation:

Alanine aminotransferase (ALT) or serum glutamate pyruvate aminotransferase (SGPT) is the enzyme produced by liver cells. It helps the body metabolize proteins. Cirrhosis is the disease in which normal liver cells are replaced by scar tissue caused by alcohol and viral hepatitis B and C. If the liver is damaged as in cirrhosis, SGPT is released into the blood and this causes SGPT levels to increase.
Thus, the correct answer is option (B), 'SGPT'.
