The STD - Basic panel contains 3 tests with 5 biomarkers.
The STD - Basic panel contains the following tests:
- Chlamydia/Neisseria gonorrhoeae RNA, TMA
- RPR (Monitor) with Reflex to Titer
- Herpes Simplex Virus 1/2 (IgG), Type-Specific Antibodies (HerpeSelect®)
Due to the consultation and reporting requirements, we are unable to offer HIV testing at this time.
Chlamydia/Neisseria gonorrhoeae RNA, TMA
Urine specimen: The patient should not have urinated for at least one hour prior to specimen collection. Female patients should not cleanse the labial area prior to providing the specimen.
Urine: Patient should not have urinated within one hour prior to collection. Female patients should not cleanse the labial area prior to providing the specimen. Direct patient to provide a first-catch urine (a maximum of 20-30 mL of the initial urine stream) into a urine collection cup free of any preservatives. 2 mL of urine specimen must be transferred into the APTIMA® specimen transport within 24 hours of collection and before being assayed. Use tube provided in the urine specimen collection kit for urine specimens. The fluid (urine plus transport media) level in the urine tube must fall within the clear pane on the tube label.
C. trachomatis infections are the leading cause of sexually transmitted diseases in the United States. C. trachomatis is known to cause cervicitis, pelvic inflammatory disease (PID), epididymitis and proctitis. It is also the most frequent cause of non-gonococcal urethritis in men. Among women, the consequences of Chlamydialinfections are severe if left untreated. Approximately half of Chlamydial infections are asymptomatic.
Neisseria gonorrhoeae (gonococci) is the causative agent of gonorrhea. In men, this disease generally results in anterior urethritis accompanied by purulent exudate. In women, the disease is most often found in the cervix, but the vagina and uterus may also be infected.
Herpes Simplex Virus 1/2 (IgG), Type-Specific Antibodies (HerpeSelect®)
HSV 1 IGG, TYPE SPECIFIC AB
HSV 2 IGG, TYPE SPECIFIC AB
Diagnose HSV infection when lesions are absent; determine HSV type
This assay utilizes recombinant type-specific antigens to differentiate HSV-1 from HSV-2 infections. A index positive result cannot distinguish between recent and past infection. If recent HSV infection is suspected but the results are negative or equivocal, the assay should be repeated in 4-6 weeks. The performance index characteristics of the assay have not been established for pediatric populations, immunocompromised patients, or neonatal screening.
Individuals infected with HSV may not exhibit detectable IgG antibody in the early stages of infection.
Herpes Simplex Virus (HSV) is responsible for several clinically significant human viral diseases, with severity ranging from inapparent to fatal. Clinical manifestations include genital tract infections, neonatal herpes, meningoencephalitis, keratoconjunctivitis, and gingivostomatitis. There are two HSV serotypes that are closely related antigenically. HSV Type 2 is more commonly associated with genital tract and neonatal infections, while HSV Type 1 is more commonly associated with infections of non-genital sites. Specific typing is not usually required for diagnosis or treatment. The mean time to seroconversion using the type specific assay is 25 days. The performance of this assay has not been established for use in a pediatric population, for neonatal screening, or for testing of immunocompromised patients.
Syphilis RPR ( RPR (Monitor) with Reflex to Titer)
This is a non-treponemal screening test for syphilis. False positive results may occur due to systemic lupus erythematosus, leprosy, brucellosis, atypical pneumonia, typhus, yaws, pinta, or pregnancy. Monitoring of RPR is helpful in assessing effectiveness of therapy.
A positive RPR screen must be followed by a specific treponemal antibody test (e.g., FTA-ABS):
A positive result on the second method confirms the screening result and the affected person is diagnosed with syphilis.
A negative result on the treponemal test may mean that the initial RPR test was falsely positive. Further testing and investigation may be done to determine the cause of the false positive.
False-positive results have been associated in patients with infections, pregnancy, autoimmune disease, old age, Gaucher disease, and malignancy.
