![]() ![]() Microdeletion Panel add-on ($425 USD) includes: Syndromes tested: Trisomy 21 (Down Syndrome), Trisomy 18 (Edwards Syndrome), Trisomy 13 (Patau Syndrome)Īdd-On Options: Fetal sex (no charge), sex chromosome aneuploidies (no charge). Vanishing twin pregnancies can still use Invitae with the knowledge that vanishing twin can affect the sensitivity and specificity of NIPS for the remaining fetus and may result in false positive or false-negative results. Invitae NIPS cannot be ordered for triplet (or higher multiple) pregnancies, miscarriage or pregnancy with a known fetal demise. Invitae NIPS can be ordered for those with a history of maternal malignancy and/or organ transplant or bone marrow transplant, though these samples may have an increased risk for inaccurate results or test failure. Analysis of sex chromosomes and five microdeletion syndromes can be added for singleton pregnancies. ![]() Invitae uses whole-genome sequencing (WGS) technology to quickly analyze cell-free DNA (cfDNA) and identify pregnancies at an increased risk for trisomy 21, trisomy18 and trisomy 13. Invitae NIPT can screen for fetal chromosomal abnormalities as early as 10 weeks for patients pregnant with singleton or twin pregnancies. This means fewer than 1 in 1,000 Harmony tests yields a false-positive result.” Length of time for results: 7-10 business daysĪccuracy: “Harmony has a less than 0.1% false-positive rate for trisomies 21, 18 and 13. Where to get it done: any hospital outpatient lab (no Lifelabs): Syndromes tested: Trisomy 21 (Down syndrome), Trisomy 18 (Edwards syndrome) and Trisomy 13 (Patau syndrome), sex chromosome abnormalities.Īdd-On Options: Fetal sex (no charge), 22q11.2 deletion syndrome
