The challenge was sent to category A, B, C, and C1 laboratories. Participants were presented with the following scenario:
A midstream urine sample with a requisition and a note arrives at the laboratory. On the note, there is a request for the laboratory to process the sample. It also indicates that the sample had been found in the patient’s fridge and had been collected at least 7 days ago. Please select the one option that best describes your lab’s protocol.
A. Process the sample and report the results as requested.
B. Reject the sample and request a new sample (if possible).
C. Process the sample and report the results with a disclaimer.
D. Process the sample and report the count and identification of the organism(s) in the culture. Susceptibilities are not reported.
MAIN EDUCATIONAL POINTS from PC123
- While refrigeration will reduce the incidence of contaminated urine samples, colony counts in refrigerated samples are considered reliable for only 24 hours.
- A patient with a serious condition benefits from the most accurate and timely information and delayed testing provides neither.
