Trimester NIPT

The only Non-Invasive Prenatal Testing Service provided from one of our clinics, or the privacy and comfort of your own home.

Trimester is a nationwide service for pregnant women. We supply NIPT and other laboratory tests for single and twin pregnancy. We can even arrange an ultrasound scan for reassurance purposes and to provide a calculated due date for your baby's birth.

Taken from just a simple blood test. Using the most advanced screening methods on a small maternal blood sample, our non-invasive prenatal tests are used to identify genetic disorders such as Down’s Syndrome and other significant chromosome conditions. This safe method of testing does not replace routine NHS antenatal screening tests however, it is the next step if, a 'higher chance' result is found. Therefore, Trimester results can be provided to you often weeks before NHS screening occurs. We hope this reduces unnecessary anxiety and NIPT carries no risk to your unborn baby.


We go the extra mile
