Test Methodology

DNA Amplification by Strand Displacement Amplification

Test Usage

Detection of Neisseria gonorrhoea in male or female urine specimens.

Test Limitations

Adequate specimen collection is important. Test should be performed on a first catch random urine specimen. Some feminine sprays, powders, spermicidal agents, and lubricants may interfere with the assay and should not be used prior to specimen collection. A negative result does not exclude the possibility of infection. Predictive value of test will vary depending on disease prevalence. Nucleic acids may persist for up to 4 weeks following appropriate antimicrobial therapy.
