Chlamydia is an infectious disease caused by chlamydia and often occurs in a hidden form. The symptoms of chlamydia are similar to those of many other diseases, so the main thing in diagnostics is conducting laboratory tests for the presence of chlamydia in the patient's body.

The clumsiness of chlamydia is due to the fact that chlamydia - not ordinary bacteria, and intracellular parasites. They can not be detected in a normal smear of secretions from the genital organs. To detect chlamydia, a special scraping or blood test for chlamydia is required. Laboratory studies of urine and sperm also serve as a good way of detecting them.

Diagnostic methods

The most reliable method for detecting chlamydia is the polymerase chain reaction (PCR). It is the PCR, as the statistics show, gives the best result. Material for its conduct is very small, and the specificity and sensitivity of the study are high enough to establish a definitive diagnosis. With the help of PCR, not only chlamydia is detected, but also related diseases that are sexually transmitted.

The immunofluorescence (RIF) reaction is carried out using a biological material taken from the urethra. The smear is painted with special reagents and then studied under a fluorescence microscope: Chlamydia are a special light.

The immunoassay (ELISA) allows the detection of antibodies in the blood, that is, immunoglobulins of classes M, G, A (IgM, IgG, IgA). It is they who enter into confrontation with Chlamydia. The appearance of these antibodies in the human body suggests that the patient is infected with chlamydia or transferred it in the past (the conclusion depends on the class of antibodies detected and their number).

The culture method (seeding) reveals the sensitivity of chlamydia to antibiotics in a particular patient. Biological material is sown in special media, grown and after a certain time determine the composition of the microflora and the influence on its growth of various antibiotics.

You can independently determine the presence of chlamydia with the help of a rapid test. Such a test is sold in any pharmacy without a prescription, but trust it is only partly: the percentage of error is very high. A positive result, as well as negative in the presence of clinical symptoms, is just an excuse for immediate referral to a doctor.
