Prenatal paternity and twin zygosity.
Non-invasive testing during pregnancy, and zygosity testing for twins who have already arrived.
Prenatal paternity.
Paternity can be determined using a simple blood-draw from the mother and a buccal-swab collection from the alleged father. This non-invasive prenatal test is completely safe for both mother and unborn child.
A blood-draw and a buccal swab
A blood sample from the mother and a buccal swab from the alleged father. Nothing is taken from the pregnancy itself.
Completely safe for mother and child
The test is non-invasive, so it carries none of the procedural risk of amniocentesis or CVS.
Ask how early it can be done
It can be performed well before birth, but the earliest point depends on the laboratory’s requirements. Call and we will confirm before you book.
Twin zygosity.
Whether twins are identical or fraternal is not always obvious, and a hospital does not always establish it.
Identical or fraternal
A straightforward cheek swab from each twin. Families ask for it out of interest, and for medical history where it matters.
Early gender
Available from the same kind of maternal sample as the prenatal test. Ask when you book.
