Gynecological analyzes: smear on the flora and culture of bacteria

most popular analysis in gynecology - a smear on the flora or bacterioscopy.A smear taken from three sections: the vagina, cervix, the external opening of the urethra using a disposable spatula (plastic rod with widened end).The material of each segment is placed on a separate slide, and then examined under a laboratory microscope.In the study determined the presence of pathogens (Enterobacteriaceae, diphtheroids mycelium, staphylococci, trichomonas, chlamydia, gonorrhea and others). quality and results of the analysis depend on the correctness of taking the material and skills laboratory.

Bacteriological examination can be carried out by seeding.In this case, the c
ultivation is performed on nutrient mediums bacteria.This method is much more effective, thanks to him, the infectious agent can be detected even at low concentrations.The method allows to calculate the number of pathogens to determine their sensitivity to antibiotics.Analysis for bacteriological examination are taken from the cervical canal using a special sterile swab.In the laboratory, seeded bacteria for this relate swab culture medium (agar-agar or gelatin).

Why do DNA diagnostics

doctor may also diagnose the DNA by polymerase chain reaction (PCR).With this method, the study of the material reveals the DNA of the pathogen, which is all the information about the cell.DNA diagnostics can detect the infection is not detectable in the smears (genital herpes, chlamydia, urea- and mycoplasmosis).The material for DNA diagnostics taken from the cervical canal sterile disposable brush.Before taking a cotton swab analysis is required to isolate and remove mucus.Despite the effectiveness of this method can not be used to determine the quality of treatment of diseases. undesirable to use PCR for the diagnosis of bacterial vaginosis.

serological diagnostic methods

In order to distinguish the disease from an acute exacerbation of a chronic infection, produces an additional method of diagnostics - detection of antibodies in the blood (serum or method).Often this analysis is prescribed to pregnant women to determine the probability of infection of the child if the pathogen is detected by DNA diagnostics.Also, women are encouraged to donate blood on this analysis when planning pregnancy.

to the unborn child is most dangerous primary infection.If a primary infection in the body develop antibodies - immunoglobulin M. Their presence in the blood indicates the presence of a hidden disease that requires treatment.If found immunoglobulins G, then the body has already developed immunity against infection, treatment in this case is not required.The simultaneous presence in the blood of both types of immunoglobulin indicates an exacerbation of chronic infection with assigned needed therapy.
