Neisseria gonorrhoeae PCR
| Abbrev Code: | NGPCR | ||
| Order Code: | LAB3497 | Order Name: | Neisseria gonorrhoeae PCR |
| Synonyms: | Chlamydia/Gono Amplified | ||
| Methodology: | Transcription-Mediated Amplification The Hologic assays combine the technologies of target capture, transcription-mediated amplification and dual kinetic assay. The detection of ribosomal RNA amplification product sequences is achieved using nucleic acid hybridization. Single-stranded chemiluminescent DNA probes are labeled and combine with amplicon to form stable RNA:DNA hybrids. Light emitted from the hybrids is measured as photon signals in a luminometer. |

Collection Instructions
| Collection Instructions: | Chlamydia trachomatis, Neisseria gonorrhoeae, and Mycoplasma genitalium by PCR Collection Instructions |
| Causes for Rejection: | Follow manufacturer's collection instructions on the collection kit package. The following specimens will not be tested:
|
| 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. |
