No.
It is a weak D red cells having a reduced amount of D antigen.
Rh blood type is determined by the presence or absence of the D antigen. People who are Rh positive have the D antigen and those that are Rh negative lack this. Some people have a variant of the D antigen, called Du. Presence of Du antigen causes lab results to report the blood type as Rh negative, although the patient behaves as an Rh positive would. Du negative means a "true Rh negative" result.
It is the equivalent to Rh negative blood. D is the antigen present on commonly termed Rh+ red cells, and the D antigen is missing on D-negative blood.
antigen D is the most important
There are about 45 different Rh antigens, the most important of which is the D-antigen.
The D antigen is considered the major antigen of the Rh system because it is the most immunogenic component, meaning it is the most likely to provoke an immune response when introduced into an Rh-negative individual. The presence or absence of the D antigen determines a person's Rh blood type, which is crucial for blood transfusions and pregnancy, as Rh incompatibility can lead to serious complications. Additionally, the D antigen's prevalence in the population makes it a key focus in blood typing and transfusion protocols.
Blood type D is not one of the four main blood type groups. There is a D antigen that is part of the Rh antigen system, but there is not a blood type group called blood type D.

The O antigen is not an antigen that may be found on the surface of an erythrocyte. A and B antigens are present in the ABO blood group system, while the Rh antigen is part of the Rh blood group system. O blood type individuals lack A and B antigens on their red blood cells.
