Anti-M 的劑量效應

又有一例血型 forward and reverse typing discrepency affected by Anti-M Ab.

Forward: anti-A(neg), anti-B(4+), anti-D(4+), interp(B+)
Reverse: A1 cell(4+), B cell(1+), interp(??)
Ab screeing(台塑生醫) with MP method: I(1+), II(2+), III(2+), Auto(neg)
Ab screeing(台塑生醫) with 4度C method: I(4+), II(4+), III(4+), Auto(4+), 室溫2分鐘後 I, Auto 會散開， II, III 不會

室溫 run panel cells, 反應價數從 neg, +/-,1+,2+,3+都有, 不能排除的有 M, Lea, E
續做 panel cells with AHG phase, 只剩3組cells 有反應，另外5組anti-M 該有的反應同時也是N(pos)，因為劑量效應，而在這裡測得 neg. 的結果。
