Abstract
The advancement of prenatal DNA technology and growing demand for early fetal sex determination have created a need for a simple and easy-to-use blood collection device that eliminates the pain and difficulty individuals encounter when utilizing traditional methods of blood collection such as venipuncture or lancet fingerstick. In this study, Gateway Genomics, the leading provider of fetal sex testing, introduces “SneakPeek Snap”, a novel microneedle-based, self-administered blood collection device that simplifies at-home blood collection for fetal sex testing. Our data confirms that, compared to lancet finger sticks, the SneakPeek Snap device provides users several advantages including significant reduction in perceived pain, greater ease of use, a shorter sample collection time, and a dramatic reduction in risk of sample contamination. Notably, blood samples collected using the Snap device were shown to be highly accurate for fetal sex determination — with an accuracy greater than 99%
