Clinical Info

The Verifi Prenatal Test with Microdeletions is a non-invasive screening option for chromosomes 13, 18, and 21, and fetal sex chromosome aneuploidies in both singleton and twin pregnancies.
It is a non-invasive screening option for standard chromosome aneuploidies, certain microdeletions, and all autosomes. Expanded panels (microdeletions or all autosomes) are optional add-ons for singleton pregnancies.
