With our microneedle test you don’t have to worry about the DNA contamination issues than can offer with finger-prick home test kits. When pricking your finger at home, it’s easy to get male DNA contamination in the sample, resulting in getting false “boy” results. That happens a lot with the “at home finger-stick kits” you mail off because DNA gets on your hands from just being around males, changing baby boy diapers, even shaking hands & touching things that males have touched. Then when you prick your finger, the male DNA ends up in the blood sample. Because the lab is testing the blood for the Y (male) chromosome, this can result in false-boy results with the at-home kits. But you don’t have to worry about that problem with the microneedle tests done at 4D Sprouts.
