Clinical Performance of the MaterniT21 PLUS LDT in Multiple Gestation Pregnancies

A Retrospective Analysis of Fetal Outcome Compared to Massively Parallel Sequencing Test Results Obtained From Multiple Gestation Pregnancies at Increased Risk for Fetal Chromosomal Aneuploidy

This study will evaluate the clinical performance of massively parallel sequencing (MPS) using the MaterniT21 PLUS LDT in the detection of fetal aneuploidy in circulating cfDNA extracted from a maternal blood sample obtained from women pregnant with a multiple gestation who were at increased risk for fetal aneuploidy.

Inclusion Criteria:

• Subject was pregnant with a multiple gestation and received NIPT with the MaterniT21 PLUS LDT and a valid test result is available;
• Subject was 18 years of age or older at the time of NIPT;
• Subject provides signed and dated informed consent in English;
