D variant Ag [Presence] on Red Blood Cells
Active
Part Description
LP412025-1 D variant
D antigen is part of the Rh blood group system. Most people have red blood cells that either express the D antigen (D+) or don't (D-), but there are some people that have a phenotype that does not strictly fall into either the D+ or D- category. There are many types of D variants. "Weak D" is a D variant in which all epitopes of the D antigen are expressed, but in smaller quantity than usual. Patients with the weak D variant do not typically have anti-D antibodies. "DEL" is a variant in which D expression is low enough that it cannot be identified using typical serology. "Partial D" is a variant in which only some epitopes of the D antigen are expressed. Patients with the partial D variant may have anti-D antibodies, specifically to those epitopes that are not expressed. Testing for D variants is especially important in patients who need chronic transfusions and pregnant women. PMID: 23432139
