Summary

Prenatal testing provides information about yourbaby's health before he or she is born. Some routine tests duringpregnancy also check on your health. At your firstprenatal visit, your health care provider will test for a number of things, including problems with your blood, signs ofinfections, and whether you are immune torubella (German measles) andchickenpox.

Throughout your pregnancy, your health care provider may suggest a number of other tests, too. Some tests are suggested for all women, such as screenings forgestational diabetes,Down syndrome, andHIV. Other tests might be offered based on your:

  • Age
  • Personal or family medical history
  • Ethnic background
  • Results of routine tests

There are two types of tests:

  • Screening tests are tests that are done to see if you or your baby might have certain problems. They evaluate risk, but do not diagnose problems. If your screening test result is abnormal, it does not mean that there is a problem. It means that more information is needed. Your health care provider can explain what the test results mean and possible next steps. You may need diagnostic testing.
  • Diagnostic tests show whether or not you or your baby have a certain problem.

It is your choice whether or not to get the prenatal tests. You and your health care provider can discuss the risks and benefits of the tests, and what kind of information the tests can give you. Then you can decide which ones are right for you.
