MLT ASCP Practice Questions: Urinalysis And Body Fluids with 100% Correct!! The indicator(s) used in the pH test region of the chemical reagent strips for urine is/are: (Choose ALL correct answers) A. methyl red B. methyl blue C. bromothymol blue D. bromothymol red - ANSWER-A & C; The indicator(s) used in the pH test region are methyl red and bromothymol blue. Typically on most chemical reagent strips for urine pH, with an increase in urinary pH, the indicators bromothymol blue and methyl red, changes from orange to green and blue. Which of the following is not a standard method for measuring the specific gravity of urine: A. Urine reagent strips B. Freezing point depression C. Refractometry D. Hydrometry - ANSWER-B; Osmolality can be measured by freezing point depression, but not specific gravity as specified in this question. The other methods are used to measure specific gravity in urine samples. The normal range for urine pH is: A. 4.6 to 8.0 B. 5.0 to 6.0 C. 5.5-6.6 D. 7.35-7.45 - ANSWER-A; Normal urine pH varies from 4.6 to 8.0. After meals, urine becomes more alkaline due to gastric acid secretion (alkaline tide). At night due to shallow breathing, it becomes more acid. A high meat diet results in a more acid urine than a vegetarian diet, due to excretion of phosphates and sulfates. Which two of the following crystalline elements are found in acid urine:
