Silly question...,but I'd really like to know,what is the difference in choosing between human and monoclonal reagents for ABO/D testing? Is it a first choice from these two?Is it the price? I work with Bio-Rad reagents and I know they have cards with human reagents but also identical cards with monoclonal reagents.Our lab use only monoclonal ones. -
We are in the process of choosing new Coag. analyzers and have narrowed it down to IL and Siemens. I was hoping to get opinions on the liquid protime reagent for the Top 350s that IL says is available. Also how is their Heparin Xa reagent. We have a CA1500 now and would change to the CA2500 but I have been having some QC issues lately but my instrument is only 12 years old. -
Hi everyone, I just received a notification from Ortho about recently transfused patients and interpretation guide. "Following centrifugation of a freshly collected patient sample drawn from a recently transfused patient, the potential exists for the donor's transfused red cells, which are denser and heavier, to concentrate at the bottom of the sample tube in a layer below the patient's own red cells, which are less dense and lighter. If the cell suspension used for testing contains a majority of transfused donor cells, unexpected patient results could be observed due to the patient cells being an absent or minor population in the prepared cell suspension. The unexpected patient result could be a result associated with the transfused donor cells, or it could be due to a mix of patient and donor cell populations" Currently I use gel for antibody screening and id and gel crossmatches only...no antigen typing or ABO typing. Do you think that I would have to change anything in my SOP's? Thank you. -
Greetings, We use the Ortho Confidence system to QC our wet reagents. I have been alerted that there will be a delay in the next lot number shipment due to the (US) government shutdown. The current lot that we are using expires 10/29/2013 and the new lot # is set to ship on 10/30/2013. My question is, can I use patient samples that have established values for QC testing for the couple of days that I am without unexpired QC material? If so, how many examples of a particular value do I have to have in order for it to be a valid QC evaluation? For instance, if I want to use a group A patient to QC the anti-A reagent, how many times does that patients blood group have to have been tested? Thanks for the input.
