Thanks, vwuite useful information. I remember the genetic counsellor talking about blood test that checks the tris but I did not investigate. I wish many people who are going through invasive procedures knew about it. Thank you
Here is some info from the company that offers it:
We are proud to offer our patients an exciting new testing option called MaterniT21 Plus. This prenatal screen is a new blood test offered through Sequenom Center for Molecular Medicine. This screen is designed to detect increased amounts of material from chromosome 21 (Down syndrome), chromosome 13 (trisomy 13) and chromosome 18 (trisomy 18) and requires only a maternal blood sample after 10 weeks of gestation. At this time MaterniT21 Plus screening is available to patients meeting one or more of the following criteria:
•Advanced maternal age (35 years or older at the time of delivery)
•Family history
•Abnormal prenatal ultrasound findings
•Increased risk based on screening results
The benefit of this screen is the high detection rates and low false-positive rates for these chromosome abnormalities with no risk to the pregnancy.
•99.1% detection for Down syndrome
•99.9% detection for trisomy 18
•91.7% detection for trisomy 13
Hope this helps! And thanks!
And congratulations on reaching the 12 weeks and hoping all goes well.
Can youbrxplain the test please. Am a bit clueless.
