Parents - Expanded Newborn Screening. Expanded newborn screening uses a new technology called tandem mass spectrometry (MS/MS) to screen newborns for over thirty disorders. Only a few drops of the baby's blood are needed to do this expanded newborn screening test. Many people are excited about expanded newborn screening because it can screen a baby for many disorders without needing more blood collected than for the current newborn screening test. Expanded newborn screening is also fast, accurate, and cheap. While expanded newborn screening using MS/MS is relatively new, tandem mass spectrometry technology has been used for many years. Scientists have used MS/MS technology to measure all kinds of different substances. For example, MS/MS technology is used in drug tests to determine what type of drug a person has taken.
