Skin scraping. Prices, reviews, ratings
Skin (cutis) is the outer covering of the human body. It consists of the epidermis (five layers of epidermal cells), dermis and subcutaneous fat (hypodermis). The functions performed by this largest human organ in terms of area are: respiratory, protective, thermoregulation and water-salt metabolism, excretory, blood storage, endocrine
Skin (cutis) is the outer covering of the human body. It consists of the epidermis (five layers of epidermal cells), dermis and subcutaneous fat (hypodermis). The functions performed by this largest human organ in terms of area are: respiratory, protective, thermoregulation and water-salt metabolism, excretory, blood deposition, endocrine and metabolic, receptor and immune. Scraping is a type of diagnostic manipulation that consists of obtaining biological samples for differential diagnostics. Distinguish between superficial and deep scrapings.
General information
The number of these manipulations may vary, for some diseases it is necessary to perform five or more repetitions, with a maximum covering the body surface, including visually unaffected areas. Sample collection sites are usually selected depending on the suspected diagnosis.
Procedure
Facial skin scraping
Tools used: a set of glasses (object and cover), Vaseline oil with a pipette, scalpels and scissors. A few drops of oil are applied to the previously prepared glass, depending on the number of samples that are planned to be obtained. The surface is fixed with the thumb and forefinger, a drop of oil is applied and carefully scraping with a blade at an angle of 90 degrees is started strictly in the direction of hair growth. The scraped samples are collected and transferred to glass.
Skin scraping for fungi involves collecting scale particles, which are then placed in an eppendorf (sealed plastic container) and sent for subsequent analysis.
It is used to determine deep and superficial mycoses (rubrophytosis, trichophytosis, microsporia, favus, epidermatophytosis, candidiasis, keratomycosis, blastomycosis, sporotrichosis and chromomycosis) caused by contagious and infectious agents.
Skin scraping for demodex is a method for diagnosing tick infestations caused by ticks of the genus Demodex, the so-called tick-borne gland (conjunctivitis, blepharitis, keratitis and episcleritis). The most common habitat of the pathogen: nose, forehead, cheeks, chin and eyelid areas. It is also found in the nasolabial folds and external auditory canal.
Objects to be examined: scales, papules and vesicles, purulent discharge and eyelashes (four to six from each eyelid). They are placed on a glass slide with a few drops of glycerin solution and covered with a cover glass.
A nail scraping for fungus is obtained with a scalpel, scissors, a dissecting needle or a drill. To dissolve the horny masses and make them transparent, they are treated with KOH solutions (caustic potash). In some cases (for the presence of pathogenic fungal spores), thin scales are additionally removed from the edges of the nail folds.
Examination and analysis of skin scrapings
The obtained samples are sent for complex diagnostics with microscopic and cultural studies, the sensitivity and effectiveness of which reaches about 50%. If it gives a negative result, they resort to PCR diagnostic tests (polymerase chain reaction), which detects fungal DNA molecules with an accuracy of up to 94%.
In cytological studies of the cervix and cervical canal, the sample is obtained by aspiration - separately from the ectocervix and endocervix - with modified spatulas such as Eyre and Cytobrash, Cervix, Papette brushes. Then the biological material is applied to a glass slide (in a thin layer), dried and protected with a cover glass with mandatory marking and patient identification.
Indications
It is used to diagnose fungal and infectious diseases and identify various types of pathologies. It is prescribed during the initial appointment and precedes the diagnosis and the start of treatment. During the therapy, it is repeated at certain intervals.
Contraindications and complications
Microscopy is performed using a minimum of equipment and does not present any difficulties with interpretation. In most cases, it allows you to make an accurate diagnosis without resorting to more complex methods.
No special measures to prepare the patient are required.
On the eve of the collection, you cannot use decorative and medicinal cosmetics.
