false positive chlamydia culture

It may show false results. I googled if UTI's produce false positives for Chlamydia, and in a study 47% of the UTI samples came back false positive. The positive Group B test did not interfere with the ELISA chlamydia screen. These tests are very good at identifying chlamydia. A test that is positive almost always means the problem is there and is unlikely to be a false-positive test result. You are right, the ELISA test does have about a 5 % false positive rate. An early morning urine NAAT test or direct cervical culture would be my recommendation. A Chlamydia blood test is done which shows the presence of the antibodies for the chlamydia trachomatis bacteria in your blood. Chlamydia, Group B Streptococcus, Cytomegalovirus (CMV) ... the clinician should be aware that rapid tests will have both false-positive and false-negative results when compared with cultures. C.trachomatis DNA was investigated by commercially available PCR (Chlamydia trachomatis 330/740 IC; Sacace, Italy) method. Because some of the other assays perform better on certain specimen types, it is important for … The NAAT tests are very accurate, even if -- like any test -- false results can occasionally occur. A false-negative result can result from poor specimen Lower genital tract infections with Chlamydia trachomatis are predominantly asymptomatic in men and women. More than two million new cases of chlamydia, gonorrhea, ... a false positive is incredibly rare (99 percent of the time tests that come back negative are accurate). Best to go for testesting. In our study, 4 (8%) of the 50 swab samples were found positive with DFA, 1 (2%) was positive with cell culture, and 1 (2%) was positive with PCR. False-positive or false-negative results are more common in these assays, especially for those specimens that have a tested value near the cut-off or the so-called ‘gray zone’area. He was tested at the same time as seeing the doctor about a really bad UTI. False-positive results can be due to cross-reaction with other bacteria from the genital tract. The results obtained demonstrate a nonspecific reaction that gives rise to false-positive results in the presence of culture media, including simple 2% agar, using the Abbott IMx SELECT C. trachomatis EIA test. It is accepted that less sensitive tests (i.e., culture and immunoassays) should not be used to confirm the results of more sensitive nucleic acid amplification tests (NAATs). This test can also be done on a urine sample. The test may come out false positive and can show the presence of antibodies which may be due to a … The Centers for Disease Control and Prevention recommended confirming positive screening tests for Chlamydia trachomatis when positive predictive values are <90%. However, the results are not conclusive. (1,2) In 2010, 1.3 million documented cases were reported to the CDC. MCRNA : Chlamydia is caused by the obligate intracellular bacterium Chlamydia trachomatis and is the most prevalent sexually transmitted bacterial infection in the United States. A polymerase chain reaction (PCR) test is an example of a nucleic acid amplification test. Diagnostic technology has provided several approaches to the diagnosis of C trachomatis.Outside of cells, Chlamydia can die or degrade without optimal storage and transportation.
