Epic Code LAB2111533 Abbott multi-Collect Chlamydia Gonococcus, PCR, Genital Swab

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.

Test Name Alias

Chlamydia trachomatis | CT GC | 8227

Interface Order Alias

11222

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 Type: Genital Swab

Container/Tube: Abbott multi-collect specimen collection kit

Collection Instructions:

 

Female

Specimens should be obtained with a swab using a speculum moistened with sterile warm water to facilitate collection.

Lubricants other than water should not be used since they can be toxic to the organism.

  1. Discard disposable transfer pipette; it is not required for endocervical swab specimen collection
  2. Remove the sterile swab from the wrapper, taking care not to touch swab tip or lay it down on any surface
  3. Insert the white tip of the specimen collection swab into the endocervix canal.
  4. Gently rotate the swab for 15 – 30 seconds to ensure adequate sampling
  5. Withdraw the swab, carefully
  6. Handle the cap and tube carefully to avoid contamination, including the outside of the transport tube and cap. If necessary, change gloves.
  7. Unscrew the transport tube cap and immediately place the specimen collection swab into the transport tube so that the white tip is down.
  8. Carefully break the swab at the scored line on the shaft; use care to avoid splashing the contents
  9. Recap the transport tube. Ensure the cap seals tightly.
  10. Label the transport tube with sample ID, including date and time of collection.
  11. Transport to lab within 24 hours at room temperature or 14 days refrigerated.

Male

  1. The patient must be instructed not to urinate at least 1 hour prior to sampling.
  2. Insert small swab 2-4 cm into Urethra.
  3. Rotate swab for 3-5 seconds and withdraw swab.
  4. Insert swab into the Abbott multi-collect transport media. Snap off shaft of swab at the score line.
  5. Leave swab in tube. Cap tube and label specimen.
  6. Transport specimen within 24 hours at room temperature or refrigerate.
