+Antepartum evaluation
Fetal karyotyping
Amniocentesis
Chorionic villus sampling
Maternal laboratory evaluation
Fetomaternal hemorrhage (e.g. Kleihauer-Betke test, flow
cytometry)
Urine toxicology
CBC Serologic testing for syphilis
Fasting blood glucose
Blood antibody screen to exclude alloimmunization

+Postpartum evaluation
Gross and histopathological information Often leads to new information that may change your original list of
differentials and change recommendations for preconception and
prenatal care Requires experienced pathologists to assist the autopsies
Estimating time of death
Brown or red discoloration of the umbilical cord = at least 6 hours
Desquamation of the face, back, abdomen = at least 12 hours Brown or tan skin = at least 24 hours
Mummification = at least 2 weeks
Histological changes of the placenta
