Gateway Genomics Products

The SneakPeek Early Gender DNA Test by Gateway Genomics is designed to specifically focus on fetal sex and return just one answer – male or female. This enables the test to be run on magnitudes smaller volumes of blood than the typical non-invasive prenatal test. When maternal blood samples arrive at SneakPeek Labs, extracted cell-free fetal DNA is run through real-time quantitative PCR to detect with a sensitivity down to a single Y chromosome. If Y chromosomes are found, the result is a boy. If they are absent, the baby is a girl. The test is run in 3 hours with 99.9% accuracy¹.
