Use

A recent American Congress of Obstetricians and Gynecologists (ACOG) practice bulletin made recommendations as to the appropriate use of laboratory tests that should be performed as part of the investigation of the cause of late term (greater than 20 weeks) fetal demise.6 The authors suggested that maternal testing for thyroid stimulating hormone (TSH), human parvovirus B19 IgG and IgM, lupus anticoagulants, and anticardiolipin antibodies could provide useful information for future pregnancy management.
