How should an individual be designated if they test negative for C, D, and E antigens in complete Rh typing?

In complete Rh typing, individuals are classified based on the presence or absence of specific Rh antigens on their red blood cells. The primary antigen of concern in the Rh system is the D antigen, which determines whether a person is classified as Rh positive or Rh negative. If an individual tests negative for the D antigen, they are categorized as Rh negative.

In this question, since the individual tested negative for C, D, and E antigens, the absence of the D antigen solidifies their classification as Rh negative. The testing does not affect the overall designation, as the key determinant of Rh status is whether the D antigen is present. Thus, an individual who is negative for the D antigen is consistently labeled Rh negative regardless of the status of the other C, c, E, or e antigens.

This classification is critical because understanding an individual's Rh status helps guide blood transfusions and can affect pregnancy care, especially in cases where Rh incompatibility is a concern.
