Biological specimen collection: non-urogenital secretion / swab / scraping
Available with home visit Collection of biological material: non-urogenital secretion / swab / scraping is a medical procedure for obtaining biological samples from various non-urogenital mucosal or anatomical surfaces for laboratory investigations.
The procedure allows collection of material required for microbiological, microscopic, cytological, rapid immunological, and molecular biology testing, contributing to the diagnosis of infections, inflammatory conditions, and other disorders.
The service includes collection of nasal, pharyngeal, nasopharyngeal, tonsillar, oral, otic, conjunctival, wound, and other similar non-urogenital secretions, swabs, or scrapings.
The service does not include venous or capillary blood collection or collection of urogenital biological material.
Indications
- suspected bacterial, viral, or fungal infections;
- inflammation of mucosal surfaces or skin;
- pathological secretions;
- microbiological or cytological evaluation;
- PCR and other molecular biology investigations;
- treatment monitoring;
- screening or clinical assessment.
Procedure
Sample collection is performed by trained medical personnel using sterile instruments and techniques appropriate for the required biological material.
Depending on the investigated area, a secretion, swab, or scraping may be collected from the mucosa or affected surface.
The collected samples are subsequently transported to the laboratory for the requested analysis.
Contraindications
- severe acute lesions in the sampling area;
- significant active bleeding;
- inability to access the sampling site;
- situations in which the procedure may worsen the local condition.
The decision to perform the procedure is made by the medical staff or attending physician.
Recovery / restrictions
The procedure is minimally invasive and usually does not require special recovery.
Temporary effects may include:
- mild local discomfort;
- irritation sensation;
- cough or sneeze reflex depending on the sampling site.
Advantages
- quick and minimally invasive procedure;
- safe sample collection under sterile conditions;
- enables accurate microbiological and molecular diagnosis;
- supports appropriate treatment selection;
- applicable for multiple types of laboratory investigations.
Preparation:
Preparation depends on the type of biological sample and the recommended investigation.
- For nasal / nasopharyngeal swabs:
avoid nasal sprays, drops, or nasal irrigation for several hours before the procedure unless otherwise recommended by the physician. - For throat / oropharyngeal swabs:
avoid food, drinks, tooth brushing, and antiseptic mouth solutions for 2–3 hours before sample collection. - For conjunctival swabs:
if possible, avoid using eye drops or ophthalmic ointments before the investigation unless otherwise advised by the physician. - For ear sample collection:
avoid self-cleaning of the ear canal before the procedure. - For wound or skin surface samples:
avoid applying local antiseptics or treatments immediately before collection unless otherwise recommended by the physician.
Patients are advised to inform the medical staff about any medications being taken, including antibiotics and antifungal drugs.
