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.

How should I prepare for a drug and alcohol screening/test coming up soon?

How should I prepare for a drug and alcohol screening/test coming up soon?

Depends: I assume you are using drugs since you asked this question. Stop using.

Some drugs, particularly marijuana, may stick around in fat cells for weeks or even a few months. There is no way to flush drugs out of the body, and masking it doesn't work. ...Read more

Does a negative westernblot for HIV1&2 (as a screening test) @ 16weeks post exposure rule out hiv1&2 100%? Do I need repeat test at 6 months? Thanks!

Does a negative westernblot for HIV1&2 (as a screening test) @ 16weeks post exposure rule out hiv1&2 100%? Do I need repeat test at 6 months? Thanks!

Wrong test, too long: The HIV Western blot test is not intended for screening and could miss some infections. You need a 4th generation (duo, antigen-antibody) test, which is conclusive any time 4 weeks or more after exposure; or a 3rd gen antibody test at least 8 weeks after exposure. Nobody needs testing as long as 6 months; even 3 month is longer than needed with modern tests. Discuss with an NHS GUM clinic. ...Read more
