Test Code
Alias/See Also
Includes
Chlamydia trachomatis

Preferred Specimen
Specimen Type: Urine
Collection Container: Urine COBAS media
Specimen Volume: 5.5 mL (sample volume must be between the two indicator lines on the tube)
Minimum Volume
5.5 mL
Instructions
- Prior to sampling, the patient should not have urinated for at least one hour.
- Direct patient to provide first-catch urine (approximately 10 to 50 mL of the initial urine stream) into a urine collection cup.
- Immediately transfer the urine into the COBAS® PCR Media tube using the provided disposable pipette.
- NOTE: If the urine specimen cannot be transferred immediately, it can be stored at 2°C to 30°C for up to 24 hours.
- The correct volume of urine has been added when the fluid level is between the two black lines on the tube label. Do not over or under fill.
- Tightly re-cap the cobas® PCR Media tube.
- Invert the tube 5 times to mix. The specimen is now ready for transport.

Limitations
A vaginal swab is the preferred specimen type for Mycoplasma genitalium testing in females due to higher sensitivity compared to endocervical swabs and urine. If the preferred specimen type is not used, further testing with the preferred specimen type may be indicated if M. genitalium infection is strongly suspected. Testing with this instrument is not available for patients <18 years old.
This test is not recommended for evaluation of suspected sexual abuse and for other medico-legal indication
Reference Range
Chlamydia trachomatis: Negative
Trichomonas vaginalis: Negative
Mycoplasma genitalium: Negative
Clinical Significance
This test should not be used to determine therapeutic success as nucleic acids may be present, and detected, after antimicrobial therapy.
A negative result does not necessarily rule out infection. Specimens containing mucus, gels, lubricants, or creams may give invalid or false negative results.
