MaterniT21 PLUS Core + ESS + SCA
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, sex chromosome aneuploidies, and an enhanced sequencing series that examines seven clinically relevant microdeletions and two additional chromosomal regions, trisomies 22 and 16.
Special Instructions
The test request form must include the patient's date of birth, gestational age, additional patient demographics, pregnancy type (singleton or multiple), donor egg status, and clinical indications for testing, such as advanced maternal age or abnormal ultrasound findings. Only specific collection kits can be used for sample collection, ensuring proper sample handling and transport.
Limitations
Although the results are highly accurate, discordant outcomes can occur due to biological factors like placental, maternal, or fetal mosaicism, maternal organ transplants, or vanishing twins. The test does not replace the precision of prenatal diagnosis with CVS or amniocentesis. It may not accurately detect fetal triploidy, balanced rearrangements, or the precise locations of duplications or deletions, and the results could be impacted by maternal BMI, weight, or systemic lupus erythematosus. Further genetic counseling and invasive prenatal testing might be necessary for evaluating positive or nonreportable results.
