You did not get a result from your non-invasive prenatal testing (NIPT). A small percentage of patients who have NIPT will get a “failed” or “no call” result.

Reasons for a “no call” NIPT

This can happen for various reasons, but the most common is:

• there is not enough DNA from the baby/placenta in the sample because of high maternal weight or because you had your blood drawn too early

How to avoid a “no call” NIPT result

• be sure to have your blood drawn at the correct gestation according to the requirements outlined by your health care provider and the NIPT lab.

Next steps

If you get a “failed” or “no call” result you will be contacted to have your blood drawn again. In the majority of cases, you will get a result from the second blood sample. If you paid for your NIPT (i.e. it was not funded by OHIP), you will not have to pay to have your blood redrawn.
