Question

Two blood screening tests can provide information about kidney function. One is the Blood Urea Nitrogen (BUN) and the other test is:

• A. Plasma Albumin
• B. Plasma Bilirubin
• C. Plasma Biliverdin
• D. Plasma Creatinine
• E.

Hint:

For kidney function, look at BUN and plasma creatinine together for an overall picture.

Answer 1

The Correct Option is D

Step 1: Understanding BUN and plasma creatinine.
Blood Urea Nitrogen (BUN) and plasma creatinine are both waste products filtered by the kidneys, and their levels indicate kidney function.
An increase in either or both suggests impaired kidney function.
Step 2: Why plasma creatinine is the other test.
Plasma creatinine is produced by muscle metabolism and filtered by the kidneys.
A rise in plasma creatinine levels occurs when the kidneys are not able to filter it efficiently.
Step 3: Analyzing other options.
- (A) Plasma Albumin: Albumin levels indicate protein levels in the blood, not kidney function.
- (B) Plasma Bilirubin: Bilirubin is a byproduct of red blood cell breakdown, not directly related to kidney function.
- (C) Plasma Biliverdin: Biliverdin is a precursor to bilirubin, not related to kidney function.
Step 4: Conclusion.
Therefore, plasma creatinine is the other test that helps assess kidney function.
