Urinalysis and Body Fluids 6th Edition by Majorie DiLorenzo, Susan Strasinger

Exercise 25

In the laboratory, a primary consideration associated with pH is:

A. Identifying urinary crystals

B. Monitoring vegetarian diets

C. Determining specimen acceptability

D. Both A and C

Step 1 of 2

Urinary pH:

• Urinary pH is a tool to analyze metabolic or respiratory based acid-base disorders and to manage the urinary condition which requires specific pH.

• Inorganic chemicals dissolved in urine are precipitated and forms renal calculi and urinary crystals.

• This precipitation and crystal formation depends on pH of urine.

• Maintaining a controlled pH reduces the cause of calculi formation. Alkaline pH will not allow calculi formation.

• Specimen should be in acceptable in nature, contaminated or unpreserved specimen will cause false results in urine pH.

Therefore, “identifying urinary crystals” and “specimen acceptability determination” is the primary concern related with pH. Hence, the correct answer is option.
