The Purpose of SMA Carrier Testing

The purpose of SMA carrier testing is to see if a couple is at an increased risk of giving birth to a child who will have SMA. SMA carrier testing is a laboratory test done on a sample of blood. If testing shows that a couple is at high risk, additional testing can be done during pregnancy to see whether or not the baby will have SMA. However, most women's test results are normal.
