Exercise 30

The primary cause of unsatisfactory results in an unpreserved routine specimen not tested for 8 hours is:

A. Bacterial growth

B. Glycolysis

C. Decreased pH

D. Chemical oxidation

Step 1 of 2

Preservation of specimen:

The specimen must be preserved for the best analysis and to avoid the infection of pathogens.

• Various preservative methods like refrigeration, adding preservatives are applied in laboratory.

• If the specimen is not preserved, it tends to give a chance to bacterial growth and the results will be false or unsatisfactory.

• The specimen should be checked before 8 hours in case of non preservation. If not it gives false result.

Therefore, the unpreserved routine specimen not tested for 8 hours in which the primary cause of unsatisfaction result is “bacterial growth”. Hence, the correct answer is option.
