[US blood bankers: How often are neonate exchange transfusions done at your hospital?]

Level 3 NICU and we have done 1 in the last 6 years.

[Is there still a good serological centrifuge out there?]

We use the Hettich and have separate programs set up so only the wash program has the longer break time included. We also have a site that set two wash programs (one for larger cell suspensions and one for cell button only) allowing only one program to be affected by the increased break time. 

[Weak D test quality control]

We have found some variation across our Transfusion Services departments who perform Weak D testing for Cord ABO/Rh testing ordered for Rhophylac work ups.  I am curious to know if testing commercially available Weak D cells is required for quality control for this test.  We all perform a DAT if the Weak D is showing a positive result and use check cells when the Weak D is showing negative results. Any feedback is appreciated, thanks!
