Fetal Risk Summary
No reports linking the use of Evans blue with congenital defects have been located. The dye is teratogenic in some animal species (1). Evans blue has been injected intra-amniotically for diagnosis of ruptured membranes without apparent effect on the fetus except for temporary staining of the skin (2,3). The use of Evans blue during pregnancy for plasma volume determinations is routine (4,5,6,7 and 8). No problems in the fetus or newborn have been attributed to this use.
