Important Note

Spectrum Health Regional Laboratory's Chlamydia and Gonococcus testing is not validated for performance on pediatric patients under the age of 14 years old.  Testing for these patients must be collected in either an APTIMA Multi-Test Swab collection kit or the APTIMA Urine collection kit and will be sent out to a reference laboratory.  Please order a Reference Miscellaneous Test (#LAB848) and indicate complete test name when pediatric testing is necessary.

Interface Order Alias


Clinical Information

The predictive value of an assay depends upon the prevalence of disease in any population. In populations where the prevalence of sexually transmitted diseases (STD) are high, a positive test result is more likely to be a true positive than in populations of low prevalence of disease.

In cases where a patient’s clinical symptoms or risk factors are inconsistent with GC or CT urogenital infection, positive results should be carefully assessed and retesting using another procedure such as culture may be necessary. Additional testing is recommended in any circumstance when a false positive or false negative result could lead to adverse medical, social or psychological consequences. Samples containing blood may give false positive results.

A negative test result does not exclude the possibility of infection which may be due to improper specimen collection, specimen mix-up, technical error, concurrent or previous antimicrobial therapy or a low number of organisms present in the specimen below the sensitivity of the test. The presence of inhibitors to polymerase chain reactions such as lubricants and cervical secretions may result in a false negative test result.

This method is approved only for male and female urines, female endocervical swabs, female vaginal swabs and male urethral swabs. Specimens from the respiratory tract, eyes, and rectum are not acceptable.

This method is not approved for use in young children.

In medical-legal cases, culture for GC and CT should also be done.

Collection Instructions

Specimen Collection: Urine (First void)

Container(s): Sterile urine cup (with lid) or Abbott multicollect kit

Preferred Volume to Collect: 30.0 mL

Minimum Volume to Collect: 10.0 mL

Neonate Volume to Collect: 10.0 mL


Collection Instructions:

  • First void ("dirty") urine is included in this collection, this is collected before a UA specimen, if both are needed.
  • Do not cleanse the genital area prior to specimen collection.

  • Patient should not have urinated for at least one hour prior to sample collection
  • Patient Collection Instructions are located in the menu on the left.
  • Specimen should not be submitted with orders for culture.

Abbott multicollect kit instructions

  • Follow directions above to obtain a first void urine specimen.
  • Discard specimen collection swab, it is not required for urine specimen collection.
  • Unscrew the transport tube cap, taking care not to spill the transport buffer within.
  • Handle the cap and tube carefully to avoid contamination.
  • Use the plastic transfer pipette to transfer urine from the collection cup into the transport tube until the liquid level in the tube falls within the clear fill window of the transport tube label or else a new specimen should be collected.

  • Do not overfill. Slightly more than one full squeeze of the transfer pipette bulb may be required to transfer the necessary volume of urine specimen.

  • Recap the transport tube carefully. Ensure the cap seals tightly.

  • Label the transport tube with sample identification information, including date of collection. Take care not to obscure the fill window on the transport tube.

NOTE (for either collection): Failure to collect a urine specimen, including the first part of the voiding, may decrease the sensitivity of this test. If the specimen cannot be delivered to the laboratory within a few hours after collection it should be stored and refrigerated until it can be delivered. Specimen must be received in laboratory for analysis within 24 hours of collection.
