What is the multiple marker screening test
The multiple marker test is a blood test offered to all pregnant women. Doctors use it to screen for chromosomal disorders and neural tube defects. Test results can be combined with first trimester screening tests to give more accurate results (this is called an integrated screening test).
What is Multiple marker screening and what is its purpose?
Multiple Marker Screening (MMS) measures specific substances in a pregnant woman’s blood originating from the fetus, the placental tissue, or a combination of both. MMS determines your risk for having a child with Down syndrome, trisomy 18 and neural tube defects (spina bifida and anencephaly).
