TypesofBloodTransfusionAllergicReactions:

1.AcuteTransfusionReactions:Thistypeofreactionoccurswithin24hoursoftransfusionandcanmanifestasfever,chills,rash,anditching.

2.DelayedHemolyticTransfusionReactions:Thesereactionsoccurdaystoweeksaftertransfusionandarecausedbyanimmuneresponsetodonorredbloodcells.

3.Anaphylaxis:Thisisasevereandpotentiallylife-threateningallergicreactioncharacterizedbydifficultybreathing,rapidheartrate,lowbloodpressure,andlossofconsciousness.
