Additional information Typing and screening of blood for transfusion. Prenatal and Maternal screens will automatically be typed for Du (weak D) at an additional charge if the mother appears to be Rh-negative and we have no previous record of Du testing. If antibodies potentially capable of causing Hemolytic Disease of the Newborn are found on the Prenatal screen, these will automatically be titered at an additional charge.
