MaterniT21 PLUS Core + SCA
The following information must be provided with the test request form: patient's date of birth, gestational age, additional patient demographic information, pregnancy type (singleton or multiple), donor egg status and the clinical indications (including advanced maternal age, abnormal ultrasound, history suggestive of increased risk for aneuploidy, positive serum screen, or other indications).
Expected Turnaround Time
4 - 7 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.

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, and sex chromosome aneuploidies.
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 for whole chromosome abnormalities (including sex chromosomes) and for subchromosomal abnormalities could lead to the potential discovery of both fetal and maternal genomic abnormalities that could have minor or no clinical significance.
Evaluating the significance of a positive or non-reportable test result may involve both invasive prenatal testing and additional studies on the mother. Such investigations may lead to a diagnosis of maternal chromosomal or subchromosomal abnormalities, which on occasion may be associated with benign or malignant maternal neoplasms. cfDNA testing may not accurately identify fetal triploidy, balanced rearrangements, or the precise locations of subchromosomal duplications or deletions; these may be detected by prenatal diagnosis with CVS or amniocentesis. The ability to report results may be impacted by maternal body mass index (BMI), maternal weight, and/or maternal systemic lupus erythematosus (SLE). The results of this testing, including the benefits and limitations, should be discussed with a qualified health care provider. Pregnancy management decisions, including termination of the pregnancy, should not be based on the results of this test alone.
This test was developed, and its performance characteristics determined, by LabCorp. It has not been cleared or approved by the US Food and Drug Administration (FDA).
Cell-free DNA is isolated from the sample and analyzed using massively parallel sequencing technology.
