Overview: Neisseria Gonorrhoeae PCR TestIntroduction: The Neisseria Gonorrhoeae PCR Test detects Neisseria gonorrhoeae DNA to diagnose gonorrhea, causing pain or discharge. Following 2023 CDC guidelines, it uses PCR for high specificity, supporting infection screening. This test is critical for guiding diagnosis, treatment planning, and improving outcomes in molecular pathology for patients with suspected gonococcal infections.
Other Names: Gonorrhea PCR Assay, Neisseria DNA Test.
FDA Status: Laboratory-developed test (LDT), meeting molecular pathology standards for diagnostic accuracy.
Historical Milestone: Gonorrhea PCR testing began in the 1990s with STI research. PCR methods improved in the 2000s, enhancing diagnostic precision.
Purpose: Detects Neisseria gonorrhoeae DNA to diagnose gonorrhea, guides treatment, and evaluates patients with pain or discharge.
Test Parameters: 1. Neisseria Gonorrhoeae DNA
Pretest Condition: No fasting required. Collect swab, urine, cervical swab, urethral swab, or saliva. Report history of pain, discharge, or STI exposure.
Specimen: Swab (sterile swab/transport medium, 1-2 swabs), Urine (sterile container, 5-20 mL), Cervical Swab (sterile swab/transport medium, 1-2 swabs), Urethral Swab (sterile swab/transport medium, 1-2 swabs), Saliva (sterile container, 1-2 mL). Transport in a biohazard container.
Sample Stability at Room Temperature: 24 hours
Sample Stability at Refrigeration: 48 hours
Sample Stability at Frozen: Not frozen
Medical History: Document pain, discharge, dysuria, or history of STI exposure. Include current medications, especially antibiotics.
Consent: Written consent required, detailing the tests purpose, gonorrhea implications, and risks of sample collection.
Procedural Considerations: Uses PCR to detect Neisseria gonorrhoeae DNA in specimens. Results are available in 3-5 days, supporting clinical decisions. Performed in laboratories, often for gonorrhea diagnosis.
Factors Affecting Result Accuracy: Low DNA yield or improper sample storage can affect results. Contamination may reduce specificity.
Clinical Significance: Positive Neisseria gonorrhoeae DNA confirms gonorrhea, guiding antibiotic therapy (e.g., ceftriaxone). Negative results may require culture testing.
Specialist Consultation: Consult an infectious disease specialist or primary care physician for result interpretation and treatment planning.
Additional Supporting Tests: Gonorrhea culture, chlamydia PCR, or STI panel to confirm gonorrhea diagnosis.
Test Limitations: Sensitivity depends on sample quality; clinical correlation is needed. False negatives may occur in low-burden infections.
