Questions and CORRECT Answers
Given the following dry reagent strip urinalysis results, select the most appropriate course of
action: pH = 8.0 Protein = 1+ Glucose = Neg Blood = Neg Ketone = Neg Nitrite = Neg Bilirubin
= Neg
A. Report the results, assuming acceptable quality control
B. Check pH with a pH meter before reporting
C. Perform a turbidimetric protein test, instead of the dipstick protein test, and report
D. Request a new specimen - CORRECT ANSWER- C
Highly buffered alkaline urine may cause a false-positive result on the dry reagent strip protein
test by titrating the acid buffer on the reagent pad. Protein should be measured by an alternate
method that is not subject to positive interference by highly buffered alkaline urine.
Given the following urinalysis results, select the most appropriate course of action: pH = 8.0
Protein = Trace Glucose = Neg Ketone = Small Blood = Neg Nitrite = Neg Microscopic
findings: RBCS = 0-2/HPF WBCS = 20-50/HPF Bacteria = Large Crystals = Small, CaCO,
A. Call for a new specimen because urine was contaminațed in vitro
B. Recheck pH because CACO, does not occur at alkaline pH
C. No indication of error is present; results indicate a UTI
D. Report all results except bacteria because the nitrite test was negative - CORRECT
ANSWER- C
A positive nitrite result requires infection with a nitrate-reducing organism, dietary nitrate, and
incubation of urine in the bladder. The test is positive in about 70% of UTI cases. Alkaline pH,
bacteriuria, and leukocytes point to UTI.
SITUATION: A 6-mL pediatric urine sample is processed for routine urinalysis in the usual
manner. The sediment is prepared by centrifuging all of the urine remaining after performing the
biochemical tests. The following results are obtained: SG = 1.015 Blood = Large Leukocytes =
Moderate Protein = 2+ RBCS: 5-10/HPF WBCS: 5-10/HPF Select the most appropriate course
of action.
, A. Report these results; blood and protein correlate with microscopic results
B. Report biochemical results only; request a new sample for the microscopic examination
C. Request a new sample and report as quantity not sufficient (QNS)
D. Recentrifuge the supernatant and repeat the microscopic examination - CORRECT
ANSWER- B
This discrepancy between the blood reaction and RBC count resulted from spinning less than 12
mL of urine. When volume is below 12 ml, the sample should be diluted with saline to 12 ml
before concentrating. Results are multiplied by the dilution (12 mL/mL urine) to give the correct
range.
Given the following urinalysis results, select the most appropriate course of action: pH = 6.5
Protein = Neg Glucose = Neg Ketone = Trace Blood = Neg Bilirubin = Neg Microscopic
findings: Mucus = Small Ammonium urate = Large
A. Recheck urine pH
B. Report these results, assuming acceptable quality control
C. Repeat the dry reagent strip tests to confirm the ketone result
D. Request a new sample and repeat the urinalysis - CORRECT ANSWER- A
Ammonium urate crystals occur at alkaline pH only. The pH should be checked, and if it is
below 7.0, the crystals should be reviewed for correct identification. The trace ketone does not
require confirmation, provided that the quality control of the reagent strips is acceptable.
Given the following urinalysis results, select the most appropriate first course of action: pH = 6.0
Protein = Neg Glucose = Neg Ketone = Neg Blood = Neg Bilirubin = Neg Other findings: Color:
Intense Transparency: Microscopic: yellow Clear Crystals, Bilirubin granules = Small
A. Repeat the dry reagent strip test for bilirubin
B. Request a new sample
C. Recheck the pH
D. Perform a test for urinary urobilinogen - CORRECT ANSWER- A
Bilirubin crystals cannot occur in urine without bilirubin. The dry reagent strip test should be
repeated, and if the result is negative, a new specimen should be requested as bilirubin may have
degraded due to storage. If a second sample yields a negative result, the crystals should be
reviewed before reporting. Abnormal crystals occur only in acid or neutral urine.
