Test Methodology

DNA Amplification by Strand Displacement Amplification

Test Usage

Detection of Neisseria gonorrhoea in male or female urine specimens.

Reference Range *

Negative

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.
