Reflex? ABO/Rh confirmation (a one-time requirement) is required before blood products can be set up. To minimize delays in product availability, if the provider mistakenly places an order for a duplicate Type and Screen test, the Blood Bank will reflexively convert that order to an ABO/Rh confirmation test (test code CHEK).
Additional information Typing and screening of blood for transfusion. 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.
