If RhD typed weak positive with anti D at immediate spin, does this reaction required IAT (Du test) or only when the typing is negative at the immediate spin then IAT required ?! 

 

It depends upon the instructions that come with the reagent.

..........and on the result of the reagent control you put up with it and what is wrong with the patient, if it's a man or a woman,and how old................and why you were doing the test in the first place

Thanks all
