title: Nonpredictive value of measurements of delta optical density at 450 nm in SS disease.
abstract: A case is reported of an elevation in values in the measurement of delta optical density at 450 nm in a patient with SS disease, mild hyperbilirubinemia, and anti-E antibody, with the birth of a nonsensitized infant. The role of maternal bilirubin in causing this spurious elevation is discussed.
