Do any labs perform weak d testing on Rh negative units, if intended for an Rh negative patient with Anti-D?  We also obviously do a full crossmatch.  We currently do this, and I just don't see the point when the blood supplier has to do the weak d in order to mark the bag as Rh neg.  

Just wanted to see if I was missing something.

Certainly, in the UK, I would be amazed if any hospital did this.  The reason I say this is because the anti-D reagents used in hospitals (according to BCSH Guidelines) should NOT detect such types as Partial D Category VI.  On the other hand, the anti-D reagents used by our Testing Departments in NHSBT are specifically designed to detect such types as Partial D Category VI, and the NHSBT "guarantees" that "what is on the tin is what is in the tin" or, to put it another way, NHSBT "guarantees" that, if we say the blood in the bag is D-, it is D- (with the possible exception of DEL, for which we do not test).

Have never tested for Weak D to confirm the Rh type of donor units labeled Rh negative in over 40 years in US.  The only reason we test with anti-D today is to detect donor center labeling errors.

I suppose it depends a bit on how much you trust your supplier........

It's not a regulatory requirement to test Rh Neg units for weak D.

Thanks everyone just needed a little validation, I'm catching some heat for trying to get rid of that policy.

Extra work with no value added - dump it!
