    Contraction Stress Test



    Why It Is Done

    A contraction stress test is done to check:

    • If your baby will stay healthy during the reduced oxygen levels that normally occur during contractions during labor.
    • If the Reference placenta Opens New Window is healthy and can support your baby.

    A contraction stress test may be done when results from a nonstress test or a biophysical profile are not in the normal range.
