J Clin Microbiol. To find out if you have a Chlamydia, you need to undergo a chlamydia test. Prevalence of C. trachomatis, sensitivity, and specificity were estimated by latent class analysis using all test results available. 2003, 361: 1792-10.1016/S0140-6736(03)13398-3. If test results aren’t immediately available, your provider will call you to discuss a positive result, offer treatment options, and make a follow-up appointment, if needed. Most C. trachomatis infections are asymptomatic. Preferred method when testing for Chlamydia trachomatis or Neisseria gonorrhoeae using a NAAT (PCR) 1 Asymptomatic females – self-collected vaginal swab A self-collected vaginal swab is the preferred testing method for chlamydia and gonorrhoea in asymptomatic females—a first catch urine should only be considered if a self-collected swab cannot be taken. Less stigma. Urine tests for chlamydia were only slightly less effective, identifying a correct positive result 87 percent of the time and a correct negative result 99 percent of the time. Table 2 shows the results of the additional tests and the conclusion (presence or absence of C. trachomatis infection) for these 28 women.

On the other hand, substantial differences in specificity between the two tests are unlikely. There were no significant differences in diagnostic outcome between cervical swabs and urine samples using the SDA technique. Similar trends are reported from Sweden, Denmark, England and the US [2–7]. The limitations of this study are mainly related to the potential bias of a discrepant analysis approach. At present, nucleic acid amplification tests (NAATs) provide unsurpassed sensitivity and high specificity when applied on cervical and urethral swabs and male urine samples. 2004, 80: 335-341. PubMed  According to investigators, “availability of new assays such as the cobas CT/NG v2.0 test provides laboratories with a comprehensive approach to genital tract [C trachomatis and N gonorrhoeae] infection testing.”.

Of the 523 C. trachomatis negative women, BDPT identified 519 as negative based on cervical swabs, and 514 based on urine samples. A total of 15 women were excluded; ten due to lack of an adequate urine sample, three due to use of antibiotics, and two because of inadequate gynaecological examination (one woman had painful genital herpes, one did not want an examination). The cervical swabs were stored at room temperature and tested within 48 hours with BDPT and within 10 days with Cobas TaqMan CT and in-house PCR. Pull back the swab without touching your skin. The present study was based on a growing request to examine urine as a supplementary or primary specimen in screening for Chlamydia trachomatis in women, with the Becton Dickinson ProbeTec (BDPT) Strand Displacement Assay (SDA). With online-only tests, you collect your own sample. Thus, both urine and cervical samples are useful for diagnostic purposes. Expel the swab from the bundle deliberately; don’t lay it down. A small brush or swab is used to take a cell sample from the vagina.

Norvegian Institute of Public Health: MSIS Report 8/2008. Uncover/unclothe yourself starting from the waist.

Comparing urine samples and cervical swabs for Chlamydia testing in a female population by means of Strand Displacement Assay (SDA). The estimates of sensitivity for C trachomatis in women ranged from 91.2% to 97.6%, depending on sample type, and 95.6% to 100.0% for N gonorrhoeae. Detection of Chlamydia trachomatis and Neisseria gonorrhoeaewith the cobas CT/NG v2.0 test: performance compared with the BD ProbeTec CT Qx and GC Qx amplified DNA and Aptima AC2 assays [published online August 20, 2018]. 1993, Boca Raton: Chapman & Hall/CRC. 2005, 142: 914-925.

Essential by WEBMD: Do not touch the delicate tip of the swab or lay the swab down. Still, it’s normal to feel a little bit anxious about the test. With both traditional in-office tests and home-to-lab tests, a trained healthcare professional collects the sample. - Case Studies There are two main ways the sample can be collected: Men will usually be asked to provide a urine sample, while women will usually be asked to either swab inside their vagina or provide a urine sample. Thus, it is important to offer sampling procedures which lower the threshold for screening and diagnostic testing in the younger age groups as well as being cost-effective. From a clinical perspective, the positive predictive value (PPV) of a test determines the proportion of patients with positive test results who are correctly diagnosed as having the infection. 2005 Dec;32(12):725-8. doi: … Of the 523 C. trachomatis negative women, BDPT identified 519 as negative based on cervical swabs, and 514 based on urine samples. On this basis, confirmation of a positive test, by sampling both urine and cervical swabs and retesting of positive tests, should be considered in screening low-prevalence groups. PubMed  Sex Transm Dis. Among these, 13% are positive for C. trachomatis. Specific testing options.

Several laboratory methods are available for direct detection of C. trachomatis, such as cell culture, immunofluorescense microscopy and enzyme immunoassays (EIA).
