Specimen Requirements

Collection

Use the APTIMA Urine Specimen Collection Kit. 1. The patient should not have urinated for at least 1 hour prior to sample collection. Female patients should not cleanse the labial area prior to collection. 2. Instruct patient to provide 20 to 30 mL of the initial urine stream (NOT midstream) into a urine cup free of any preservatives. Collection of larger volumes of urine may result in rRNA target dilution that may reduce test sensitivity. 3. Remove the cap and transfer 2 mL of urine into the Urine Transport Tube using the disposable pipette provided. The correct volume of urine has been added when the fluid level is between the black lines on the urine transport tube label. 4. Re-cap the urine specimen transport tube tightly and label with two identifiers. Store and transport at room temperature or refrigerated. See http://www.pathology.med.umich.edu/handbook/Tables/Aptima_Urine.pdf for collection procedure guide.
