4011. Urogenital smear for the microflora (on glass)

A urogenital smear (flora smear) is a laboratory test that assesses the state of the microflora in the vagina, urethra, and cervical canal, as well as detects signs of inflammation and certain microorganisms that may be associated with its development..

A urogenital smear analysis for microflora is a laboratory test that involves examining a biological specimen under a light microscope. This bacterioscopic examination makes it possible to assess the presence and nature of an inflammatory process in the genitourinary organs, determine the state of the normal microflora, and detect potentially pathogenic bacteria. This method is one of the basic methods used for the initial laboratory assessment of the urogenital tract.

Microscopic examination of a smear for microflora is used to assess the microflora of the urethra, vagina, and cervical canal. The test determines the amount of mucus, leukocytes, and squamous epithelial cells, as well as detects microorganisms that may cause infectious and inflammatory diseases of the genitourinary system. The test is one of the main laboratory assessment methods that can raise suspicion of bacterial vaginosis and is part of a standard gynecological examination.

Bacterioscopy is widely used both during routine gynecological examinations and when symptoms may indicate an inflammatory or infectious process. It may be recommended in cases of changes in the nature of vaginal discharge, itching, burning, unpleasant odor, discomfort, or pain, as well as when planning a pregnancy or monitoring the state of the microflora after treatment. The results of a urogenital smear are interpreted by a physician comprehensively, taking into account the clinical presentation, examination findings, and results of other laboratory tests.

Under normal conditions, the vaginal microflora consists of a variety of microorganisms, among which lactobacilli predominate in most healthy women of reproductive age. They produce lactic acid and other biologically active substances that maintain the acidic vaginal environment (pH approximately 3.8-4.5), provide natural protection of the mucous membrane, and inhibit excessive growth of opportunistic and pathogenic microorganisms.

In addition to lactobacilli, other microorganisms may also be present as part of the normal microflora, including anaerobic bacteria, fungi of the genus Candida, Gardnerella vaginalis, staphylococci, and other representatives of the opportunistic flora. Under normal conditions, they do not cause disease; however, if the balance of the microflora is disrupted or the number of lactobacilli decreases, they may multiply excessively and contribute to the development of an inflammatory process. Such changes may be associated with fluctuations in hormone levels, the use of certain medications (particularly antibiotics), reduced immune defenses, concomitant diseases, or other factors.

Normal gynecological smear findings

Normally, a urogenital smear contains lactobacilli, mucus, squamous epithelial cells, and leukocytes within the reference (normal) ranges, which depend on the site from which the specimen was collected – the vagina, cervix, or urethra. A predominance of lactobacilli indicates a balanced state of the vaginal microflora, whereas an increased number of leukocytes may indicate an inflammatory process.

The detection of spores or mycelium of fungi of the genus Candida may indicate candidiasis, while the detection of trichomonads, gonococci, or other microorganisms characteristic of an infectious process requires further assessment by a physician. The presence of erythrocytes in the smear is also evaluated in the context of the clinical situation, as it may be associated with the specimen collection procedure or physiological conditions, as well as with pathological changes.

A general flora smear is one of the basic laboratory diagnostic tests that allows assessment of the vaginal microflora and detection of signs of inflammation. At the same time, this method has certain diagnostic limitations: it cannot detect all infectious pathogens or accurately identify their species. If abnormalities are found in the results or relevant clinical symptoms are present, a physician may recommend additional laboratory tests, including bacterial culture, PCR testing, or other modern diagnostic methods, to clarify the cause of the changes and select the optimal treatment approach.

A urogenital smear analysis for microflora may be performed as part of a routine preventive examination or when symptoms or clinical indications are present.

Indications for a flora smear

The main situations in which the test may be recommended include:

• a routine gynecological examination to assess the state of the microflora, even in the absence of symptoms;
• pregnancy planning or preparation for assisted reproductive technology procedures;
• unusual vaginal discharge (changes in color or consistency, the appearance of curd-like discharge, or an unpleasant odor);
• itching, burning, or discomfort in the external genital area;
• lower abdominal pain, pain or burning during urination or sexual intercourse;
• suspected infectious and inflammatory diseases of the genitourinary system;
• preparation for gynecological procedures or surgical interventions (hysteroscopy, cervical biopsy, intrauterine device insertion, etc.);
• monitoring the state of the microflora after treatment;
• long-term use of certain medications that may affect the balance of the vaginal microflora;
• pregnancy – as recommended by a physician to assess the state of the microflora and detect signs of inflammation or infectious changes at an early stage.

Conditions detected by a flora smear

The results of microscopic examination may reveal signs of the following pathological conditions:

• bacterial vaginosis – an imbalance of the natural vaginal microflora characterized by a decrease in the number of lactobacilli and predominance of anaerobic bacteria;
• candidiasis – a fungal infection of the vaginal mucous membrane associated with excessive growth of fungi of the genus Candida;
• vaginitis – inflammation of the vaginal mucous membrane;
• cervicitis – inflammation of the cervical mucous membrane;
• urethritis – inflammation of the urethral mucous membrane;
• certain sexually transmitted infections, including trichomoniasis or gonorrhea, when characteristic microscopic findings are present.

Important: A flora smear has certain diagnostic limitations and cannot detect all sexually transmitted infections. In particular, chlamydial infection, mycoplasmosis, ureaplasmosis, and most viral infections cannot be detected by conventional microscopy. If necessary, a physician may recommend additional tests, including PCR testing or bacterial culture.

• Smear on glass slide (various types depending on the test)
