ABO and Rh typing

ABO  Forward Group		ABO Reverse Group		Rh*		Interpretation
anti-A	anti-B	A1 cells	B cells	anti-D	Rh control	A Neg
4+	0	0	4+	0	0

High protein anti-D used requiring manufacturer's Rh control.

Antibody screen and crossmatch

Cells	PEG IAT	CC	Donor Number	PEG IAT	CC
Screen Cell I	0	2+	450559	0	2+
Screen Cell II	0	2+	450575	0	2+
Screen Cell III	0	2+
autocontrol	0	2+

PEG = polyethylene glycol    IAT = indirect antiglobulin test    CC = IgG sensitized red cells
w+ = microscopic positive; SOP requires adding sensitized red cells to IATs that are w+

 Donors are group A Rh negative
