Intended Use

Presumptive detection of Neisseria gonorrhoeae based on the detection of gonococcal DNA in female endocervical and male urethral specimens. Because of some crossreactivity with DNA from N. meningitidis and some other members of the genus Neisseria, the test cannot be used with rectal or throat specimens.

Device Story

GONOSTAT® Gonococcal Detection Kit is an in vitro diagnostic test for presumptive detection of Neisseria gonorrhoeae. Device utilizes DNA detection technology to identify gonococcal DNA in clinical specimens. Intended for use by laboratory professionals to assist in clinical diagnosis of gonococcal infection. Output provides presumptive identification, aiding healthcare providers in determining appropriate patient treatment. Modification from predicate device involves updated labeling based on additional clinical study data supporting performance in low prevalence female populations.

Clinical Evidence

Clinical study conducted at five sites using endocervical specimens (N=3318). Results: 98.3% sensitivity, 99.3% specificity, 94.4% positive predictive value, and 99.8% negative predictive value.

Technological Characteristics

DNA-based detection reagent kit. Technological characteristics are identical to the predicate device. No specific materials, energy sources, or software algorithms are detailed in the provided documentation.

Indications for Use

Indicated for presumptive detection of Neisseria gonorrhoeae in female endocervical and male urethral specimens. Contraindicated for use with rectal or throat specimens due to cross-reactivity with N. meningitidis and other Neisseria species.

Regulatory Classification

Identification

Neisseria spp. direct serological test reagents are devices that consist of antigens and antisera used in serological tests to identify Neisseria spp. from cultured isolates. Additionally, some of these reagents consist of Neisseria spp. antisera conjugated with a fluorescent dye (immunofluorescent reagents) which may be used to detect the presence of Neisseria spp. directly from clinical specimens. The identification aids in the diagnosis of disease caused by bacteria belonging to the genus Neisseria, such as epidemic cerebrospinal meningitis, meningococcal disease, and gonorrhea, and also provides epidemiological information on diseases caused by these microorganisms. The device does not include products for the detection of gonorrhea in humans by indirect methods, such as detection of antibodies or of oxidase produced by gonococcal organisms.

GONOSTAT® Gonococcal Detection Kit Name: DNA Reagents, Neisseria Classification Name: GONOSTAT® Gonococcal Detection Kit III. Predicate Device: ### IV. Description of the Device: The device is a modification of the predicate device which is also marketed by Sierra Diagnostics, Inc. The device labeling was changed to reflect the results of additional clinical studies that support claims for the use of the device in low prevalence female populations. ### V. Intended Use: Presumptive detection of Neisseria gonorrhoeae based on the detection of gonococcal DNA in female endocervical and male urethral specimens. Because of some crossreactivity with DNA from N. meningitidis and some other members of the genus Neisseria, the test cannot be used with rectal or throat specimens. ### Technological Characteristics of Device Compared to Predicate VI. Device: The technological characteristics of the two devices are identical {1}------------------------------------------------ ### Summary of Clinical Data VII. An additional clinical study was performed using endocervical specimens at five study sites. The results of this study support the following changes and additions to the product labeling: - A new table of female endocervical specimen results obtained from the a) new study has been added. A summary of the table contents is provided below (N=3318): | Sensitivity: | 98.3% | |----------------------------|-------| | Specificity: | 99.3% | | Predictive value positive: | 94.4% | | Predictive value negative: | 99.8% | - c) Deletion of statements concerning lack of data in low prevalence populations. - d) An analysis of prevalence by sample type and clinical site has been added. - e) A chart of hypothetical predictive values at different prevalence rates has been added. {2}------------------------------------------------ Image /page/2/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
