Final Labeling- Segment Testing


Recommended Posts

I'm looking for some advice from some experienced Donor Centers.

 

We are recently taking over some "new" to us activies, which includes Final Labeling.

 

My question is whether ABO/Rh needs to be confirmed by a serological test from an attached segment AFTER labeling the product?

 

I can't find anything in the AABB standards that require additional serological testing from a segment after labeling.

 

As a matter of fact, I don't see anything that requires a collection facility to perform any segment testing.

 

Any advice would be greatly appreciated.

 

Thanks

Hi Stephanie,

 

I am not sure that you, as a collection facility, need to perform this test.  I suspect most donor centers do not.  We have a hospital based donor center and label our products in our component lab and then confirm their type in our transfusion service.

 

I have no idea if donor centers we purchase blood from do a confirm type, regardless, we always confirm the type of a product in our transfusion service before we make it available.

 

AABB

5.9.5 There shall be a method to confirm that the ABO/Rh label is correct. Confirmation shall be performed after the ABO and Rh label has been affixed to the units.

See Standard 5.12.  Before transfusion, the ABO of...component and the Rh type...labeled as Rh negative shall be confirmed by a serologic test from an integrally attached segment.......

Although this standard is in the transfusion service related activities section of the Standards, some donor centers perform this testing so the transfusion services do not need to repeat.  Note that the standard does not specify WHO does the test, only that it be performed.  If your donor center is not making these claims on the products distributed to transfusion services, then only 5.9.5 applies.

I think David is right, standard 5.12 is under the heading "Transfusion Service-Related Activities" which I think makes it pretty explicit that the transfusing facility is responsible for this confirmation prior to transfusion. Standard 5.12.1 states discrepancies must be reported to the collecting facility, implying that it is not the collecting facility that is performing the confirmation. All the computer systems I've seen for blood bank have a transitional status for red cells that requires the retype to be performed prior to the units being available for crossmatch.

Earlier this week at the 2015 AABB Annual Meeting "Ask the Standards" session, the AABB confirmed testing performed by the donor center as specified in this standard, DOES meet the intent since the Standard does not specify WHO does the testing, only that it be performed before transfusion.

My understanding is that when collecting the blood from the donor; several tubes are collected and sent off for testing at a BIG lab, this includes the ABO/Rh (as well as bacteria, diseases etc.). The donor center would only test ABO/Rh if the BIG lab determined a serological discrepancy or if the ABO/RH was a historical mismatch for the donor (these would be resolved by a tube not segment). The only time a donor center would need to confirm an ABO/Rh by a serological test from an attached segment AFTER labeling is if the donor center's reference lab was working as a transfusion service for a hospital.

For us blood grouping regarding the donor unit is done 

1- ( Segment ) after collecting upon recieving at separation area. 

2- Tube + Segment ( donor screening ) 

3- Segment with the Cross matching as final typings.
