BMC’s Yawkey building doors are now closed as an entrance as part of our ongoing efforts to enhance our campus and provide you with the best clinical care.

All patients and visitors on our main campus must enter our hospital via Shapiro, Menino, or Moakley buildings, where they will be greeted by team members at a new centralized check-in desk before continuing to the hospital. We are excited to welcome you and appreciate your patience as we improve our facilities.

Amniotic Fluid Test (AFT)

Select your language:

An AFT or Amniocentesis is a medical test performed when a woman is 20 weeks pregnant.  It is used to look for birth defects and genetic abnormalities in the fetus, and can also determine the baby’s gender.  For this test, a doctor uses a needle to remove a small amount of amniotic fluid, which contains fetal tissue. The tissue is then examined.
