The recommendations of the Ministry of Health indicate that the biomaterial must be taken from two locations: the oropharynx and the nasopharynx, otherwise there is a possibility of getting a false negative result. When taking a smear, the sterility of the probes and tubes where the sample is placed is important. In addition, the healthcare provider must wear clean, disposable gloves. To correctly take a sample, the physician must first treat gloved hands with an antiseptic, and then spread a napkin on the table, on the right side of which the spent consumable is placed, on the left - unused. After that, he must put on a second, non-sterile pair of gloves over the first and collect the biomaterial with a probe, pressing the patient's tongue with a sterile spatula. When a patient takes a swab himself, there is a high chance that not enough cells will reach the probe. This can be due to the wrong location for the collection of cells, cough or gag reflex. Before the analysis, it is recommended not to eat, drink, brush your teeth, rinse your mouth, chew gum, or smoke for at least an hour. You can also not rinse your nose or instill medicine.
