What can monoclonal antibodies help detect that can cause disease?
Immunoassays use monoclonal antibodies to diagnose infections, such as human immunodeficiency virus (HIV) , malaria and chlamydia . This can make disease identification much easier. Monoclonal antibodies have been made for antigens found on: the bacteria chlamydia trachmatis which is the cause of the disease chlamydia.

What antigens are associated with red blood cell immunosuppression?
Red blood cell antigens include the Kell antigen and the Rh antigen. 1 If you have the Rh antigen, you are considered Rh positive. 2 If you are Rh negative and your unborn baby is Rh positive, your body may begin to make antibodies… 3 Both Kell antigens and Rh incompatibility may cause a mother to make antibodies against her baby’s…
Why did the NBS contact us about anti-Fy3?
The NBS contacted us later that evening to inform us that she had developed anti-Fy3 and that a search of the country had identified only four compatible RhD− units, two of which were in the frozen blood bank in Liverpool. None of these could be rapidly obtained and so overnight she was managed without transfusion.
