How To Prepare
You will be asked to empty your bladder just before the
test.
You will need to sign a consent form that says you understand the
risks of amniocentesis and agree to have the test done. Talk to your doctor
about any concerns you have about the need for the test, its risks, how it will
be done, or what the results will mean. To help you understand the importance
of this test, fill out the
medical test
information form
(What is a PDF document?).
If you have premature labor or problems with this pregnancy, such
as
placenta previa or
placenta abruptio, an amniocentesis will probably not
be done because of your higher chance for problems.
