The Full Story

I’ve previously had a boy. Will that skew my results? Clinical studies have shown that fetal DNA clears from mom’s bloodstream between a few hours to 2 days after birth.  

I’m having twins. Can Sneak Peek determine fetal sex for each one? In the case of identical twins, if male DNA is found, then both babies are boys. If no male DNA is found, then both babies are girls. For fraternal twins (or more!), finding male DNA will confirm at least one baby is a boy, but can not distinguish if the second is a boy or girl.


Do hormone disorders such as PCOS affect my results? Sneak Peek is a DNA-based test, so hormones do not impact results. 


Do blood thinners affect my results? Sneak Peek looks only for the presence of Y chromosomes and is extremely sensitive and accurate. No blood thinners or other drugs are known to impact Sneak Peek gender results.


Is this test safe? Sneak Peek Clinical is a non-invasive prenatal test (NIPT), and it’s safe for both mom and baby.
