Hello all. I am new at the forum. I've developed a computer blood bank application with ISBT 128 standard. Now I have a customer that do the following procedure: Has 450 ml Whole Blood unit. When he needs a pediatric unit he divide it into two units, one of 400 ml and another of 50 ml. When he needs another one he divide the 400 ml into two units, one of 350 ml and another of 50 ml. And so on... Example: Original unit: 00 (500 ml) First aliquot: 00 (500 ml) -> A0 (450 ml) and B0 (50 ml) Second aliquot: A0 (450 ml) -> Aa (400 ml) and Ab (50 ml) Third aliquot: Aa (400 ml) -> ??? (This is the problem) My question is, is this procedure correct? How ISBT 128 implements this procedure?
