Instructions Specimen: First-void urine (patient should not have urinated for one hour prior to specimen collection)
Volume: 2 mL of a 15 mL urine collection
Container: cobas(R) PCR Urine Sample Kit
Collection: URINE SPECIMEN PATIENT SELF-COLLECTION: Wash hands prior to collection. Patient should not have urinated for at least one hour prior to specimen collection. Direct patient to provide a FIRST-CATCH URINE (approximately 10 to 50 mL of the initial urine stream) into a urine collection cup. Female patients should NOT cleanse the labial area prior to providing the specimen. Close the lid of the urine cup securely, label and date. CARE PROVIDER SPECIMEN: Prior to sampling, the patient should not have urinated for at least one hour. Given that collection of larger volumes of urine may reduce test sensitivity, please direct patient to provide first-catch urine (approximately 10 to 50 mL of the initial urine stream) into a urine collection cup. Immediately transfer urine into the cobas(R) PCR Media tube using the provided disposable pipette. The final volume must be between the two black lines on the tube label. Tightly re-cap the cobas(R) PCR Media tube. Invert the tube 5 times to mix. The specimen is now ready for transport.
