Correct option is C
Sol. Serum transaminases like ALT (alanine aminotransferase) and AST (aspartate aminotransferase) are enzymes released into the blood when liver cells are damaged. These are key indicators in Liver Function Tests (LFTs) and help detect conditions like hepatitis, cirrhosis, and liver damage due to toxins or drugs.
Explanation of each option:
· (a) Glucose tolerance test – Used to evaluate blood sugar metabolism and screen for diabetes, not liver function.
· (b) Creatinine clearance test – Assesses kidney function by measuring filtration rate; not related to liver assessment.
· (c) Serum transaminase – Correct Answer. ALT and AST levels are elevated in most liver diseases. Used widely to monitor hepatitis, fatty liver, and liver toxicity.
· (d) Serum electrolytes – Reflect fluid balance and kidney function but are not specific indicators of liver damage.
