The minimum age required for gargle sampling goes from 6 to 5 years in screening clinics in the Laurentians

Offered in screening clinics for COVID-19, the gargle sampling method is now extended to children aged 5 and over. Less invasive, this new method is obtained by the saliva collected when the person gargles with spring water.

In order for the sample to be correct, it is strongly recommended to practice gargling at home before going to the clinic. To do this, 5 ml of water and a small cup are needed. As requested during screening, the person should gargle with water for 5 seconds in the mouth, then 5 seconds in the throat (head back). This sequence must be done twice. Whether for children or adults, a non-compliant gargle sample cannot be analyzed in the laboratory. The test will then be done using a swab from the throat and nose.
