The Gonorrhea Rapid Test is a rapid, direct binding test for the visual detection of gonorrhoea antigen, in the secretory specimen from urogenital system.
Test results are unambiguous and can be read in 10-20 minutes. The test kit is easy to operate and does not involve washing or comparison to standards.
Gonorrhea (colloquially known as the clap) is a common human sexually transmitted infection caused by the bacterium Neisseria gonorrhoeae. The usual symptoms in men are burning with urination and penile discharge. Women, on the other hand, are asymptomatic half the time or have vaginal discharge and pelvic pain. In both men and women if gonorrhea is left untreated, it may spread locally causing epididymitis or pelvic inflammatory disease or throughout the body, affecting joints and heart valves. Treatment is commonly with ceftriaxone as antibiotic resistance has developed to many previously used medications. This is typically given in combination with either azithromycin or doxycycline. There have been some strains of gonorrhea showing resistance to ceftriaxone.
Principle Of The Test
The Gonorrhoe Rapid Test is based on the principle of double sandwich immunoassay for the detection of gonorrhoea antigen in the secretory specimen. Monoclonal and polyclonal antibodies are employed to identify gonorrhoea specifically. Both sensitivity and specificity of the test are higher than those of the present methods, which often involve long hours of culturing the collected specimen. Test results are not affected by any medication that is being taken. Results are read visually without any instrumentation. This test is ideal for screening specimen samples containing at least 1 x10⁵ bacteria per ml. The assay is conducted by adding diluted swabbed discharge specimen to the test device and observing the formation of coloured lines. The specimen migrates via capillary action along the membrane to react with the coloured conjugate. Positive specimens react with the specific coloured antibody conjugates and form a coloured line at the test line region of the membrane. Absence of this coloured line suggests a negative result. To serve as a procedural control, a coloured line will always appear at the control line region if the test has been performed properly.
