Questions: If an individual's erythrocytes exhibit surface antigen D, the person is said to be Rh negative.
True or False
Transcript text: If an individual's erythrocytes exhibit surface antigen $D$, the person is said to be $R h$ negative.
True or False
Solution
The answer is False: If an individual's erythrocytes exhibit surface antigen $D$, the person is said to be $Rh$ positive.
Explanation:
The presence of the $D$ antigen on the surface of erythrocytes (red blood cells) indicates that the person is $Rh$ positive. This is a key factor in determining the $Rh$ blood group system.
If the $D$ antigen is absent, the person is considered $Rh$ negative.
Therefore, the statement that having the $D$ antigen makes a person $Rh$ negative is incorrect.
