Hello everybody, we had a case here in our blood bank,one OPD male patient age 25 years came to our hospital for arranging blood for his elective surgery,when we perform his blood group the reaction were as under, (we are using ortho Auto Innova in our blood bank glass beads technology) Anti A Anti B Anti D Rhc a1cells bcells Interp 0 0 4 0 0 4 ABO discrpancy. Blood group rechecked with tube technique and got the same result as above.Further ..... Two more sample were collected along with the XM sample at the same time for CBC and Urea, I checked both the samples and both were clear cut O positive with +4 with a1cells and +4 with bcells in reverse group.we asked for reacollection and with the new sample the result was group O Positive.this Patient came alone and all the three sample for XM ,Urea and CBC were collected at the same time.Anybody encounter a case like this,or is it possible?all the comments will be appreciated.
