AST important enzyme to detect abnormality in:
- A- Liver disease.
- B- Heart disease.
- C- Liver and heart disease.
- D- Non of the above.
The correct answer is C- Liver and heart disease.
Here's why:
AST (aspartate aminotransferase):
- AST is an enzyme found in various tissues throughout the body, including the liver, heart, muscles, and kidneys.
- When cells in any of these organs are damaged, AST leaks into the bloodstream.
- Measuring the level of AST in the blood can therefore help diagnose and monitor a variety of conditions.
AST as a marker:
- Liver disease: AST is particularly important for detecting liver disease. Elevated levels of AST are often seen in conditions like hepatitis, cirrhosis, and alcohol-related liver disease.
- Heart disease: While not as specific for heart disease as other markers like CK-MB, AST can also be elevated in cases of heart attack and heart muscle damage.
Therefore:
- Option A, Liver disease, is partially correct but doesn't capture AST's role in heart issues.
- Option B, Heart disease, is only partially true and misses AST's significance for liver health.
- Option D, None of the above, is incorrect as AST plays a role in detecting both liver and heart abnormalities.
Conclusion:
- AST is an important enzyme for detecting abnormalities in both liver and heart disease, making C the most accurate answer.
Additional notes:
- AST levels should always be interpreted in conjunction with other clinical findings and tests for a complete picture.
- Other enzymes, like ALT and CK-MB, can provide further information about the specific location of cell damage.
