Question:

What happens if the result is inconclusive?

Our answer:

If the result is deemed inconclusive, then we offer to repeat the test on one occasion.

Aside from the replacement kit or any sampling fees, this will be free of charge.

The most likely explanation for this will be that there was not enough foetal DNA in the mother’s blood stream for us to conduct the assay.  Generally, this is because the sample has been taken too early in the pregnancy.  We realise that it is not always easy to predict the “10 weeks” and generally, a repeat sampling a few weeks later will solve this problem.

If on the second attempt the assay still fails and we are sure the sampling has been at or after the 10 week cut off, then we will be providing additional advice.
