Transport: Deliver the specimen to the laboratory as soon as possible.
Refrigeration: If a delay is necessary, refrigerate the specimen for up to 24 hours. Refrigeration is also recommended if the sample cannot be delivered within 4 hours, to prevent bacterial overgrowth.
Temperature: Specimens for bacterial culture should be transported at room temperature, but refrigeration is acceptable for delays up to 24 hours.

Bacterial overgrowth: Leaving the sample at room temperature for more than 4 hours can lead to bacterial overgrowth, which may affect results.
PCR inhibition: Certain substances in the urine can inhibit the PCR reaction. This is why proper collection and prompt delivery are critical to avoid a “”PCR inhibition present”” result.
Contamination: External contamination from skin flora or improperly collected samples can lead to inaccurate results.
Patient instructions: Instruct the patient to cleanse the genital area before collection, especially for a clean-catch midstream sample.
Sample type: Midstream clean-catch is preferred for a clean sample. The first voided urine of the morning is also often ideal.
Patient identification: Label the container clearly with the patient’s full name, date of collection, and time of collection.
Communication: Clearly communicate with the patient about the collection procedure to ensure they provide a proper sample.
Clinical information: Ensure the requisition form contains all necessary information, including the patient’s clinical diagnosis, to aid the laboratory in correctly interpreting the results.
