How do Healthyr’s at-home tests work?

Healthyr's at-home tests are simple and convenient to use. Once a few drops of blood are added to the ADX card, the specialized filtration paper separates the blood solids (red blood cells) from the blood serum, which is the clearish fluid visible in the rectangular section of the card. It's important to note that the lab actually tests the blood serum, not the red blood.
