Prenatal paternity and twin zygosity.
Non-invasive testing during pregnancy, and zygosity testing for twins who have already arrived.
Prenatal paternity.
A blood sample and a cheek swab
A blood sample from the mother and a cheek swab from the alleged father. Nothing is taken from the pregnancy itself.
No risk to the pregnancy
Because nothing invasive is done, there is no procedural risk of the kind carried by 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.
