About service
A gynecological swab for flora is a standard test that helps assess the state of the microflora of a woman's reproductive organs and is performed during almost every visit to the gynecologist.
What is a Swab for Flora?
A swab for flora (or vaginal smear) is an analysis in which biological material is collected from the mucous membranes of the genital organs (GO) to determine their microbial composition. The primary goal is to assess the state of the microflora and identify possible deviations, including inflammation, infectious diseases, or dysbiosis. Microflora refers to the totality of microorganisms inhabiting the mucous membrane of the GO. In a healthy woman, it is predominantly represented by Lactobacilli (Döderlein's bacilli), which provide protection against pathogenic flora.
In the laboratory, the biological material is examined under a microscope, assessing indicators such as: the quantity of squamous epithelium, the level of leukocytes, the presence of pathological microorganisms (cocci and diplococci, fungal spores or mycelium, motile bacteria).
Indications for the Analysis
A swab for flora is prescribed in the following situations:
• Preventive examination, which involves regular checking of the reproductive system's condition.
• Suspicion of infections.
• Lower abdominal pain. In this case, it is necessary to rule out inflammatory processes.
• Pregnancy planning. At this stage, it is important to assess the state of the microflora before conception.
• After treatment for infections to monitor the therapy's effectiveness.
• Before surgical procedures, to prevent infectious complications.
It is recommended that all sexually active women get tested at least once a year.
How is the Swab Taken from the Genital Organs?
The procedure is performed in the gynecological office using sterile instruments and includes three main stages:
• Patient preparation. The doctor asks the woman to take a comfortable position on the gynecological chair.
• Material collection. Using a disposable spatula or a special brush, the specialist gently collects biological material from the mucous membranes of the genital tract. It is then applied to a glass slide and sent to the laboratory.
How is the Analysis Taken from the Urethra?
The procedure may be slightly uncomfortable but is usually easily tolerated. The material collection is performed as follows:
• The doctor inserts a thin applicator 1–2 cm into the urethra.
• With delicate rotational movements, the biological material is collected, which is then applied to a slide and examined in the laboratory.
This examination allows the detection of inflammatory processes in the urethra, as well as sexually transmitted infections (STIs).
How is the Swab Taken from the Cervix?
Collecting material from the cervix is an important part of diagnosing infections and preventing oncopathology. A special cytobrush is used for this to collect cells. The procedure is as follows:
• The swab is taken from the vagina, cervical canal (cervix), and urethra (urinary canal).
• The collected biological material is applied to a slide or placed in a transport medium.
Epithelium in the Swab for Flora Analysis
The epithelium lines the mucous membrane of the vagina, cervix, and urethra. Its cells are constantly renewed, so their presence in the flora smear is normal. They perform a protective function, creating a barrier against infections and maintaining the health of the mucous membrane.
Normal Epithelium in the Swab
Normally, the number of epithelial cells ranges from 5 to 10 per high-power field (HPF) of the microscope. The epithelial level may depend on the menstrual cycle, hormonal background, and the woman's age.
Increased Epithelium Count
If an excessive amount of epithelial cells is found in the swab, this may indicate inflammatory diseases such as colpitis (vaginitis), cervicitis, or urethritis.
Absence of Epithelium
The complete absence of epithelial cells is less common and is often associated with atrophic changes in the mucous membrane. These are characteristic of the menopause period, when estrogen levels decline. This leads to the thinning of the mucous membrane and a decrease in its protective properties.
If the test results show deviations from the norm, it is necessary to consult a doctor. They will determine the cause of the changes and prescribe appropriate treatment or additional examinations.
Leukocytes in the Swab for Flora
White blood cells play a significant role in immune processes, protecting the body from infections and inflammation.
Normal Leukocyte Count
Depending on which part of the genital organs the swab is taken from, the normal number of leukocytes may vary slightly:
• In the vagina - up to 10 leukocytes per HPF.
• In the cervix - up to 30 per HPF.
• In the urethra - up to 5 per HPF.
If these values are not exceeded, it indicates the normal state of the mucous membrane and the absence of active inflammation.
Increased Leukocyte Count
If a significant increase in the leukocyte level is found in the swab, this may indicate the presence of inflammatory diseases. For example:
• Vaginitis – inflammation of the vaginal mucous membrane, often caused by infection or microflora disruption.
• Endocervicitis – an inflammatory disease of the inner cervical canal, which may also be associated with infections.
• Urethritis – inflammation of the urethra, often associated with STIs.
An increase in the number of white blood cells can also occur due to mucosal trauma, after sexual intercourse, or medical procedures. In any case, this requires additional examination to identify the cause. The doctor may prescribe PCR for infection detection, ultrasound of the genitourinary system, or a bacteriological culture (bacterial smear/culture) to clarify the diagnosis.
Monitoring the leukocyte level helps to timely detect inflammatory processes, which prevents the development of complications such as chronic infections or infertility.
Mixed Flora in the Swab
This is a condition where both beneficial microorganisms and opportunistic pathogens are simultaneously present in the biological material. Normally, Lactobacilli dominate the vagina, maintaining a normal acid-base balance and protecting against infections. However, in case of microflora disruption, cocci, fungi (Candida), Gardnerella, and other opportunistic bacteria may appear, for example.
Mixed flora in the swab can arise for various reasons, including:
• Hormonal imbalance, for example, when taking oral contraceptives, during pregnancy, or menopause.
• Antibiotic use: by killing both pathogenic and beneficial microorganisms, antibacterial drugs can lead to dysbiosis. This happens especially often with their prolonged use.
• Presence of bacterial or fungal infections, including STIs (syphilis, gonorrhea, chlamydia, and trichomoniasis).
In the case of the predominance of opportunistic microorganisms (cocci, Gardnerella, etc.), diseases such as:
• Bacterial Vaginosis – a disruption of the normal microflora, in which the number of Lactobacilli significantly decreases, and the quantity of anaerobic bacteria, such as Gardnerella, increases.
• Candidiasis (Thrush) – a fungal infection caused by the overgrowth of Candida fungi.
When mixed flora is detected, it is important to conduct additional diagnostics to identify the cause of the imbalance.
Pathological Microorganisms in the Swab for Flora Analysis
Their detection requires special attention, as it may indicate the development of the following diseases:
• Gonococci - bacteria that are the causative agents of gonorrhea. This is an STI that affects the mucous membranes of the genital organs and can also affect the eyes, throat, and rectum. Symptoms include painful urination, copious discharge, and lower abdominal pain. If gonococci are found, antibiotic therapy is necessary to prevent complications such as infertility or chronic inflammation.
• Trichomonads. These are microorganisms that cause trichomoniasis, one of the most common STIs. Trichomoniasis can be asymptomatic but often causes itching, burning, foul-smelling discharge, and painful intercourse. Trichomonads can also lead to cervical inflammation (cervicitis) and an increased risk of infertility. This disease is treated with antimicrobial drugs.
• Microscopic fungi, for example, of the genus Candida, are the cause of candidiasis (thrush). This is a fungal infection that usually manifests as curd-like discharge. Candidiasis can occur with decreased immunity, after antibiotic therapy, and also during pregnancy or menopause due to hormonal changes. Therapy usually involves the use of antifungal drugs, both topical and systemic.
• Coccal flora - a group of bacteria, mainly consisting of streptococci and staphylococci, which can cause vaginal dysbiosis. When it develops, cocci very often come to the forefront instead of Lactobacilli, which can lead to various inflammations (vaginitis, cervicitis). Antibiotics, drugs to restore microflora, and lifestyle adjustments are used for therapy.
The detection of pathological microorganisms in the swab for flora requires immediate response and correct treatment. Untimely treatment can lead to the development of chronic diseases, as well as negatively affect reproductive function.
