Sudden Infant Death Syndrome (SIDS): Exams And Tests

Exams and Tests

No diagnostic exam or test can predict whether a baby is likely to die of sudden infant death syndrome (SIDS).

A thorough investigation is conducted after every suspected SIDS incident. The baby's funeral can be held before the report is complete. Exams and tests related to the investigation include:

• An autopsy performed by a medical examiner (preferably one experienced in identifying diseases and causes of death in babies). This may include X-rays, blood tests, and tissue cultures to rule out other causes of death.
• Questions regarding the parents' and the child's medical histories.
• A careful examination of where the baby died.

Early Detection

There are no known tests that can determine whether a baby may die of SIDS, even for those who are suspected of having a higher risk.

Machines called apnea monitors have been used on some babies believed to be at high risk for SIDS. These machines sound an alarm when they detect a lapse in breathing. But monitoring a baby's breathing while asleep has not been shown to prevent SIDS.
