We recommend blowing your nose prior to collecting your swab sample - especially if you are already congested. You’ll want to collect a sample without a large excess of mucus.
If you use nasal sprays, neti pots, or other nasal products, we recommend waiting at least one hour after using the product, as well as blowing your nose prior to testing. Ideally, you would use a nasal product only after collecting your sample.
Please avoid collecting swab samples from anywhere but the nasal cavity. Please do not include multiple samples or sample types in one test. Metrix is only authorized for use with either nasal swab or saliva. Any other use has not been validated, and results cannot be guaranteed.
