Second-Trimester Exams and Tests
Routine exams and tests
At each prenatal visit, you can expect to be weighed and have your blood pressure checked. Your urine may also be checked for bacteria, protein, or sugar.

Pregnant women and their partners can choose whether to have tests for birth defects. It can be a hard and emotional choice. You need to think about what the results of a test would mean to you and how they might affect your choices about your pregnancy. You and your doctor can choose from several tests.

Second-trimester tests for birth defects can be done between 15 and 20 weeks of pregnancy. The triple or quad screening checks the amounts of three or four substances in a pregnant woman's blood. They can also be done as part of an integrated screening test. Amniocentesis may also be done to find certain birth defects.
