Guidelines for Establishing a Maternal Serum Alpha-Fetoprotein Screening Program

Abstract

Maternal serum alpha-fetoprotein (MSAFP) screening of all pregnant women between 15 and 20 weeks gestational age is generally recognized as a standard of care in current obstetric practice. There are many factors to consider when deciding to establish MSAFP testing as an in-house procedure versus ship-out testing by a reference laboratory at fee-for-service cost. In this report, we review clinical and analytical aspects of MSAFP testing, along with appropriate guidelines for establishing an on-site MSAFP screening program.
