Before collecting your DNA sample, please create a Circle account and register your barcode so that we can connect the DNA sample with your personal information.
It is also important to take note to refrain from eating, drinking, smoking or chewing of gum 30 minutes before providing your DNA sample. This is to prevent contamination that may cause inaccurate results.
If you find that your cheeks are too dry to swab, we recommend gurgling with a little plain water prior to collecting your sample.
