Question

Serum creatinine level helps in measuring the function of

• A. Liver
• B. Heart
• C. Kidney
• D. Lung

Hint:

Creatinine = Kidney; it is the most common "renal function test."

Answer 1

The Correct Option is C

Step 1: Concept
Creatinine is a waste product produced by muscle metabolism that is primarily filtered out of the blood by the kidneys.

Step 2: Meaning
Measuring the concentration of creatinine in the serum provides an indication of the glomerular filtration rate (GFR).

Step 3: Analysis
If kidney function is impaired, the organs cannot effectively filter creatinine, leading to an increase in serum levels. Other organs like the liver or heart use different biomarkers (e.g., ALT or Troponin).

Step 4: Conclusion
Therefore, serum creatinine is a standard diagnostic marker specifically for assessing kidney health and function.

Final Answer: (C)
