MaterniT21 is a commonly utilized non-invasive prenatal test (NIPT) that many expectant parents consider during pregnancy. This test offers a method for early screening of certain fetal conditions. A frequent question among those undergoing this procedure is how long it typically takes to receive the results.
What MaterniT21 Screens For
MaterniT21 PLUS is a non-invasive prenatal test (NIPT) that analyzes cell-free DNA (cfDNA) circulating in the mother’s blood. This cfDNA originates from the placenta, which shares genetic material with the developing fetus. The test screens for chromosomal abnormalities, which are conditions caused by an extra or missing copy of a chromosome.
Specifically, MaterniT21 PLUS screens for common trisomies, including Trisomy 21 (Down syndrome), Trisomy 18 (Edwards syndrome), and Trisomy 13 (Patau syndrome). It can also detect less common trisomies like Trisomy 16 and Trisomy 22. Beyond trisomies, the test identifies sex chromosome aneuploidies, which involve abnormal numbers of X or Y chromosomes, and certain microdeletions, where small parts of chromosomes are missing.
Average Wait Time for Results
The typical turnaround time for MaterniT21 results can vary. Labcorp, the company that processes MaterniT21 PLUS, often states that results for the core panel are usually available within 3 to 5 calendar days after the sample arrives at their lab.
While the official turnaround time is often within a few business days, individual experiences may differ. Some individuals report receiving their results in as little as four days, while others might wait closer to a week or even up to two weeks.
Influences on Result Delivery Time
Several factors can influence how quickly MaterniT21 results are processed and delivered. The volume of samples being processed at the laboratory at any given time can affect turnaround times. National holidays or weekends may also extend the waiting period, as lab operations might be reduced or sample shipping could be delayed.
Occasionally, an initial blood sample might be insufficient, necessitating a re-draw. This can occur if there isn’t enough fetal DNA (fetal fraction) in the sample, which directly delays result delivery. Shipping times from the collection site to the processing laboratory can also impact the overall timeline, especially for samples collected in distant regions.
How Results Are Delivered
MaterniT21 results are typically sent directly to the healthcare provider who ordered the test. This usually includes obstetricians or genetic counselors. The provider then communicates these results to the patient, often during a scheduled follow-up appointment or a phone call. Patients who have signed up for the Labcorp Patient Portal may be able to view their results online once they become available. If results are not received within the expected timeframe, patients should contact their healthcare provider’s office for an update on the status of their test.
