Jane12 25 Posted November 9, 2017 Share Posted November 9, 2017 Hello All, I am trying to revise our Blood bank policies and wanted to make some desirable changes in practice. We have been ordering " Antigen Tested Units " from our Blood supplier and have been repeating antigen testing in house to confirm them. I am not sure if we are required to repeat the testing because of regulations? I do not want my staff to repeat the testing. Can someone please enlighten me with details? Thanks in advance for your time. Link to post Share on other sites
Kathyang 50 Posted November 9, 2017 Share Posted November 9, 2017 When we order antigen testing, we don't re-test the unit. We do order historically tested units from our blood supplier and then we test it. exlimey 1 Link to post Share on other sites

We do order historically tested units from our blood supplier and then we test it. That's what we do as well. If the unit comes from the supplier with an antigen test result on a separate tag, we do not retype it. We also get a historical database from our supplier to test our own units. exlimey 1 Link to post Share on other sites
SMILLER 872 Posted November 9, 2017 Share Posted November 9, 2017 There are two types of "antigen negative" units we can get from our supplier here in Michigan. One is "historically negative" -- those have to be retested when they arrive. The other type is "confirmed" -- those units have been confirmed negative for a particular antigen at the supplier and do not need to be retested here.

Jane12 25 Posted November 10, 2017 Author Share Posted November 10, 2017 Thanks much for all the information. This Blood Bank community is of immense help & I really value your opinion. I am fairly new at my job as a Lead and counting on you for advice. Gnapplec and BBNC17 2 Link to post Share on other sites
Baby Banker 86 Posted November 10, 2017 Share Posted November 10, 2017 We test if the patient already has the antibody. We've had units come in that were marked one thing but were actually the opposite. BldBnker 1 Link to post Share on other sites

gagpinks 49 Posted November 11, 2017 Share Posted November 11, 2017 In UK we don't have to worry about retyping donor unit. Our national blood service give 100% assurance of their testing. Link to post Share on other sites

Marianne 66 Posted November 14, 2017 Share Posted November 14, 2017 AABB standard 5.13 states 5.13 Serologic Confirmation of Donor Blood Red Cell Antigen Other Than ABO/Rh Red Blood Cells products labelled as negative for red blood cell antigens other than ABO and RhD do not require repeat testing for the labeled antigens Link to post Share on other sites

Under collection facility standards, 5.8.4 says that untested units for "other" antigens may be labeled negative only if units from two previous donations were tested by the collection facility. Does anyone get this kind of information from their blood supplier? We just either get a "confirmed negative" or a "historical negative" label, with the historical label specifically stating that confirmatory testing must be done. So I guess we are stuck with that. Not really much of an issue here though! Scott Link to post Share on other sites

SMILLER 872 Posted November 14, 2017 Share Posted November 14, 2017 Right. They also have to include things like expiration date. product code, etc. So between the tag from us and they label already on the unit, I guess it is all covered. Scott Link to post Share on other sites
BldBnker 36 Posted November 14, 2017 Share Posted November 14, 2017 We do the antigen testing for units ordered from our blood service. We have found units that were supposedly negative for an antigen but actually positive. We also are required by our computer system to enter the antigen testing results for a unit before it will allow the selection of that unit to a patient with the corresponding antibody.

How do you handle those that you don't have antisera for - like Vel for example? Malcolm Needs and Carrie Easley 1 1 Link to post Share on other sites

SMILLER 872 Posted November 19, 2017 Share Posted November 19, 2017 Right. But please look at AABB standard 5.8.4. As I mentioned above, the donor processing facility can only label a unit as tested negative (far a particular antigen) if that has been done on two separate occasions. In that case, or if the unit in question was tested by the donor facility, the donor facility could indeed label the unit as "negative for RBC antigens". Otherwise, it would have to be tested, either by the donor facility or when it reaches your blood bank. After all, every donation by a donor is typed twice for ABO before a patient gets it.

Laurie Underwood 36 Posted November 20, 2017 Share Posted November 20, 2017 Same as Eagle Eye and we just had a patient with Anti-Vel last month. Would not have been able to retest the units sent by our blood supplier. tricore and Malcolm Needs 2 Link to post Share on other sites
BldBnker 36 Posted December 8, 2017 Share Posted December 8, 2017 We have the ability to program our system to accept "untested" units for selection for antigens that do not have available anti-sera, like Cob, Bga, or Vell etc. We use SoftBank. AMcCord 1 Link to post Share on other sites
Barb Thompson 28 Posted December 27, 2017 Share Posted December 27, 2017 We don't retest because we do not have the antisera. So far we have not had any issues. We only stock Rh, K, FyA and JkA. Link to post Share on other sites

I am hoping this was reported by the FDA by the blood supplier. Scary. @Baby Banker This should never happen ever. Edited January 24, 2018 by Gnapplec Link to post Share on other sites
