Maternal Serum Alpha Fetoprotein (MSAFP)

This procedure is usually done around the 16^th to 18^th week of pregnancy. You will be given a blood test that detects low levels of MSAFP and information telling you what the results could mean. Before having the test done, it is best to realize false positives are common.

The test can indicate the following things:

Spina Bifida (opening in the spinal column)
Anencephaly (missing part of the brain)
Down Syndrome
Other Chromosomal Abnormalities

What if the test indicates low levels of MSAFP?

Usually the doctor will tell you that false positives are common and you can have some other tests to backup the MSAFP. They may do an ultrasound, amniocentesis (increases chance for miscarriage) or other testing procedures.

This calculator predicts ovulation dates based on the date of your last period and the length of your menstrual cycle. It provides approximate dates only. Having intercourse during the few days before ovulation will give you the best chance of becoming pregnant. Since sperm can survive for several days, keep in mind that these are not the only days to become pregnant.

Remember: If your periods are irregular, this calculator is not a good way to predict your ovulation dates. Speak to your doctor about other ways to help you identify when you can conceive.
