HELPING PATIENTS UNDERSTAND NONINVASIVE PRENATAL SCREENING (NIPS/NIPT)
As a healthcare provider, you know that offering NIPS (NIPT) is standard of care for all pregnant patients and that it’s important patients understand what their results may indicate, the possibility of false positive and false negative results and the importance of follow-up diagnostic testing, if clinically indicated.1
When patients are considering NIPS (NIPT) and have questions about the screening, we’d like to offer some insights that can help you educate your patients about the difference between screening and diagnostic tests and their respective benefits and limitations.
NIPS (NIPT) offers advances over older technologies because it’s much more sensitive and is accepted as standard of care as a screening test.1

All screening tests, including NIPS (NIPT), can result in rare false positive or false negative results.2,3 Since the sample obtained for an NIPS (NIPT) test includes DNA fragments from both the developing placenta and the pregnant patient, differences in either of these could suggest an increased risk to the developing fetus. However, there can be cases with:
Diagnostic testing, if clinically indicated, can help determine if the atypical fragments identified are truly reflective of a fetal condition.
For patients who are unsure of the difference between screening and diagnostic testing, it’s important to provide clarity. NIPS (NIPT) is a screening test, meaning it’s designed to identify whether your pregnancy is at increased risk to be affected with the condition being screened. Diagnostic tests, on the other hand, can provide a definitive “yes” or “no” diagnosis for the condition in question.
