Answer to Question 1

ANS: C
Cold-reactive autoimmune hemolytic anemia caused by anti-A or anti-D is sometimes secondary after infections such as M. pneumoniae and infectious mononucleosis.

Answer to Question 2

ANS: B
When red cell agglutination is noted on a blood film, the blood should be warmed to 37 C for 15 minutes and the automated analysis of the specimen repeated while the blood is warm. This patient most likely has a cold agglutinin, and it will disassociate from the red cell membrane and agglutination reverse when the specimen is warmed. Valid results can thus be obtained.
