Answer :
Answer:The correct answer is d. Specimen dilution.
The discrepancy between the reagent strip and microscopic results can be attributed to specimen dilution. Here's why:
- The reagent strip shows a specific gravity of 1.010, which indicates a diluted specimen.
- The microscopic examination shows a high number of red blood cells (>100) and white blood cells (25-50), which is inconsistent with the reagent strip results.
- The reagent strip shows negative or trace amounts of protein, glucose, ketones, and blood, which is inconsistent with the microscopic findings.
Specimen dilution can cause:
- False-negative results on the reagent strip
- Incorrect specific gravity readings
- Inconsistent results between the reagent strip and microscopic examination
The other options are less likely to cause the discrepancy:
a. Instrument out of calibration: This would affect all results, not just the discrepancy between reagent strip and microscopic results.
b. pH is too alkaline: The pH is within the normal range (7.0), and an alkaline pH would not typically cause this discrepancy.
c. Microscopic accidentally performed on a different specimen: This is unlikely, as the results are from the same urinalysis test.
Note: This question requires knowledge of urinalysis and laboratory testing. If you have any further questions or need clarification, feel free to ask.
