Question

A lab technician added few drops of antigenD to a blood sample. what is the aim of him by doing so?

Answer 1

The correct answer is - To check the presence of a Rh antigen.

Antigen D, also called the Rhesus (Rh) factor, is a type of an immunoglobulin which is found in the human blood. Anti-sera D provides the antibody component for the antigen D in the human blood.

When the Rh factor is present in the blood, it is called as Rh-+ and when it is absent, it is called as Rh-. So, if the antigen is present in the blood, upon addition of the antiserum, the antibody and antigen for the Rh factor will react and agglutinate to form a complex.

Answer 2

To check the presence of a Rh antigen, the lab technician added few drops of Antigen D to the blood.

Antigen D is also called the Rhesus (Rh) factor, is basically a type of an immunoglobulin which is found in the human blood. Anti-sera D provides the required antibody component for the antigen D in the human blood.

When the Rh factor is present in the blood, it is called as Rhesus positive and when it is absent, it is called as Rhesus negative. So, if the antigen is present in the blood, upon addition of the antiserum, the antibody and antigen for the Rh factor will react and coagulate to form complex.
