How the gender blood test works
From around 6 weeks of pregnancy, small fragments of your baby's DNA (cell-free fetal DNA) cross the placenta and circulate in your own bloodstream. A simple venous blood sample is all that's needed to look for them.
- 1
Fetal DNA enters your blood
Cell-free fetal DNA passes through the placenta and mixes with your own DNA in the maternal bloodstream.
- 2
One small blood sample
Your phlebotomist takes a routine venous sample at our Widnes or Crewe clinic — nothing invasive, no risk to the pregnancy.
- 3
The laboratory looks for Y-chromosome DNA
If male (Y-chromosome) DNA is detected, you're expecting a boy. If none is found, you're expecting a girl — with 99.9% accuracy.
What this test measures
