Red blood cells with partial D antigen type as D-positive, but individuals often produce anti-D when stimulated by transfusion or pregnancy. Some partial D, similar to weak D, result from point mutations in RHD that cause single amino acid changes. Historically, weak D red blood cells were defined as having decreased D antigen levels that required the indirect antiglobulin test for detection. Weak D phenotype most commonly results from a single point mutation in the transmembrane domain of the RHD gene.
No special preparation is needed for DU Test. Inform your doctor if you are on any medications or have any underlying medical conditions or allergies before undergoing DU Test. Your doctor depending on your condition will give specific instructions.
