MaterniT21 PLUS Core (chr21,18,13,sex)
Use
For pregnancies at increased risk of fetal abnormalities, the MaterniT21 PLUS test delivers a comprehensive NIPT for the analysis of chromosomal regions including trisomies 21, 18, and 13, fetal sex.
Special Instructions

Limitations
While the results of these tests are highly accurate, discordant results, including inaccurate fetal sex prediction, may occur due to placental, maternal, or fetal mosaicism or neoplasm; vanishing twin; prior maternal organ transplant; or other causes. Cell-free DNA (cfDNA) testing does not replace the accuracy and precision of prenatal diagnosis with CVS or amniocentesis. A patient with a positive or high-risk score test result should be referred for genetic counseling, and tests are not intended to identify pregnancies at risk for neural tube defects or ventral wall defects. cfDNA testing may not accurately identify fetal triploidy, balanced rearrangements, or the precise locations of subchromosomal duplications or deletions. It may be impacted by maternal body mass index (BMI), maternal weight, and maternal systemic lupus erythematosus (SLE).
