Mix and Match - High Incidence Antigens

A Blog from Eric Ching:

Hope you are enjoying this hot summer unless you live in the BC interiors☹.

Just to follow up my last entry on the “allo’s to hi’s”, my wish to you is that you won’t encounter any one of the following antibodies. When you encounter an alloantibody to a high incidence antigen, the ethnic origin of the patient may give you a clue to the possible identity of the antibody.

Enjoy the rest of the summer!

Eric
