Msafp Screening Test (Overview)

Alpha-fetoprotein (AFP) is a protein that is normally produced by the fetus' liver. AFP is present in the fluid around the fetus (amniotic fluid) and a small amount crosses the placenta and moves into the mother's blood stream. As the baby grows and produces more AFP, the amount in the mother's blood increases. Between weeks 15 and 20 of a pregnancy, a maternal serum alpha-fetoprotein (MSAFP) screen may be offered. It's usually as part of a set of tests, which screen for genetic problems, called the quad screen. The AFP blood test determines how much AFP is in the mother's blood. The other tests measure the levels of other pregnancy hormones, including estriol, human chorionic gonadotropin (HCG), and inhibin A.

Do I need to have down's screening tests?

Screening can help: There is no requirement for a patient to have an invasive diagnostic test like amniocentesis to determine if a fetus has trisomy 21. However, most OB providers offer the screening test to pregnant women. Both should be accompanied by counseling so that couples can discuss them and the pregnant woman can decide what testing, if any, to undergo. ...Read more

Is a drug screening easier to pass than a regular drug test?

No difference : I'm not sure if there is really any difference. I am not sure I understand your question. Screening tests have room for error and false positives.
