Exercise 33

Bacterial growth in an unpreserved specimen will:

A. Decrease clarity

B. Increase bilirubin

C. Decrease pH

D. Increase glucose

Step 1 of 2

Bacterial growth:

Bacteria are microorganisms, which multiply rapidly and cause disease to human beings and other organisms.

• In an unhygienic condition, the bacteria multiply.

• The bacterial growth is high in an unpreserved specimen.

Clarity of specimen:

• The clarity is more important in the specimen for urine analysis.

• The clear sample without any cloudy appearance means it has no bacterial growth in it.

• The bacterial growth in the specimen gives a cloudy look, so decreases the clarity of specimen.

Therefore, in an unpreserved specimen, the bacterial growth leads to “decrease in clarity” of specimen. Hence, the correct answer is option.
