Collection Instructions

Collection Instructions:Neisseria gonorrhoeae by PCR Collection Instructions
Causes for Rejection:
Follow manufacturer's collection instructions on the collection kit package. The following specimens will not be tested:
  • Midstream and catheterized urine specimens
  • Overfilled or under filled urine transport tubes
  • Urine in the grey top aliquoted tube (with preservative)
  • Transport tubes containing a large, white cleaning swab
  • Transport tubes containing more than 1 swab
  • Transport tubes with the absence of a collection swab
  • Transport tubes containing a swab not included in the collection kit

Note: Specimen source must be approved for the collection kit used. See collection instructions above for suitable sources for each type of APTIMA collection kit.    

Contraindications:Per manufacturer's insert, the performance of the vaginal swab specimen has not been evaluated in pregnant women or teenage women less than 16 years of age.


Processing and Shipping

Specimen Processing:

Swab specimens:

After collection, transport and store swab in the swab transport tube at 2°C to 30°C. Specimens  must be assayed within 60 days of collection.

 

Urine specimens:

After collection, transport processed urine specimens in the APTIMA urine transport tube at 2°C to 30°C. Processed urine specimens must be assayed within 30 days of collection.

 

Urine samples that are still in the primary collection container must be transported to the testing lab at 2°C to 30°C. Urine must be transferred to the APTIMA urine specimen transport tube within 24 hours of collection.

 

Shipping Instructions:

Swab specimens:

After collection, transport and store swab in the swab transport tube at 2°C to 30°C. Specimens  must be assayed within 60 days of collection.

 

Urine specimens:

After collection, transport processed urine specimens in the APTIMA urine transport tube at 2°C to 30°C. Processed urine specimens must be assayed within 30 days of collection.

 

Urine samples that are still in the primary collection container must be transported to the testing lab at 2°C to 30°C. Urine must be transferred to the APTIMA urine specimen transport tube within 24 hours of collection.

 

Specimens should be sent in individual bags to limit the possibility of cross contamination.

 

Test Performed at or Referral Lab Infectious Diseases Diagnostic Laboratory  (UMMC East Bank)


Interpretive

Reference Range:

Negative for Neisseria gonorrhoeae by PCR.

 

Limitations:As is true for all urine test methods, a negative urine result for a female patient who is clinically suspected of having chlamydial or gonococcal infection does not rule out the presence of CT or GC in the urogenital tract. Testing of an endocervical specimen is recommended in such cases.
