The quantity of DNA required for the analysis is obtained with an oral swab. The procedure to obtain the sample is simple, painless and can be carried out at home or in the clinician’s office. The sample collection kit contains all necessary materials and instructions in a very detailed way.
Before taking the sample;
Hands must be washed properly, or disposable gloves should be used.
Patients should avoid eating, smoking, alcohol, drinking (water is the exception) or brushing teeth at least 1h before scraping.
Patients are advised to rinse the mouth with water before scraping.
Informed consents must be filled and signed by the clinician and the patient.
Removal of the swab from the swab tube.
The inside part of one of the cheeks must be scraped energetically with the scraping end of the swab for 1 minute, while rotating the swab. The scraping end of the swab should only be in contact with the inside of the cheek.
The swab must be left to dry for 10 minutes, out of the tube, avoiding contact with any surface.
The swab should be stored back in the tube and closed.
The process must be repeated using the other swab, scraping the inside part of the other cheek.
