All our tests offer fast results with a high degree of precision, however they differ in the way the sample is taken and the method of analysis. Nasal swab testing is less invasive, as it is not necessary to insert the swab deep into the nasal cavity, as in the case of nasopharyngeal swabbing, but instead collects some fluid from the nose, in the lower turbinate. This makes the tests ideal for children and people who are sensitive to pain.
