“There can be no good result without a good sample”
This is a key step for the reliability of the results which is why our healthcare professionals are trained in taking this type of sample. A swab is taken from both the throat and nose (with the same swab bud) to increase the reliability of the examination. First the throat, then the nose, as recommended by the government.
The swab used is specifically designed to minimize the inconvenience caused to the patient: they are thin and flexible to ensure a test that is not painful.
