Non-stress is only an indirect test, so caution is needed when drawing a conclusion about the results obtained, in which the absence of an increase in the rate and the loss of intrinsic oscillation of the fetal heart rate can have a pathological meaning of the fetal condition and is more of an alarm sign than a real diagnosis.

Non-stress test is one of the tests that pregnant mothers need to perform during pregnancy, especially 1-2 months before the expected date of birth. This is a prenatal test that helps doctors monitor the fetal heart rate when the baby is resting and when the baby is active (fetal movement).

Rh incompatibility occurs when a pregnant mother with Rh-negative blood comes into contact with Rh-positive blood from her fetus, resulting in the development of Rh antibodies in the mother's body. This causes the fetus to become anemic, which can lead to hemolytic disease of the newborn. In severe cases, it can lead to death. Therefore, all pregnant women need to be tested for Rh during pregnancy.

When a mother and her fetus carry different Rhesus (Rh) protein factors, the condition is called Rh incompatibility or Rh factor incompatibility. This condition occurs when the mother is Rh negative and the fetus is Rh positive.

Pregnancy is a very important but also a worrying time for women. Most babies are born healthy, but prenatal testing (including prenatal screening and prenatal diagnostic testing) can provide valuable information about the baby's condition while it is still in the womb.
