Hurray for p value - we use it every day too! We do not use the equation above but use the standard 3 postive and 3 negative reactions (from AABB Technical Manual).

Yes Kathy, I would challenge the deficiency. I consider blood removed from a validated 1-6 C cooler "in transport" not "storage" so a Safe T Vue 10 temp indicator should be acceptable. As far as taking temps every 4 hours when blood is in coolers -> there was a little blurb in AABB News a few years ago that specifically stated that validated coolers were exempt from the 4 hour requirement. (I wish I could find the article but I can't)

Is a recrossmatch by IAT a requirement in the UK? It is not in the US. At our facility we would not do this if the transfusion reaction workup is negative.

I agree with your techs. Do a transfusion reaction investigation and if negative continue to issue any previously allocated units.

We will continue to give AHG compatible units, even if it is not detectable. We may eventually start giving electronic crossmatch after review by pathologist. R1R2

Not to get off topic too much, is anyone including an immediate spin when doing a prewarm crossmatch?

I agree with Malcolm

Did your manual test include an immediate spin?

I agree with dlb, this is a complete waste of time, don't overthink this. R1R2

Pick the samples you use for the study carefully. Pick a postiive sample that will work with all methods, like a 4+ anti-D.

We do not accept a unit back if it was spiked. I encourage the RN to try to complete the transfusion within 4 hours of entry or discard the unit. I will update the BB records if unit was not transfused and discarded in the patient care area.

I agree with Dansket

I agree David, but I have seen this. It didn't make sense to me either.

Hi Brenda, Does the laboratory always have A2 cells? Some do not carry them anymore.

No, they do not ask. I don't know of any facility that does ask. R1R2

I like your idea!

We run ficin with IgG cards manually.

We do not follow Ortho's recommendation and run all ficin testing in IgG gel.

Sounds like a great challenge! Good Luck to you!

I agree with Liz

I agree with Terri. We like it a lot, and QC it annually.

I am just curious as to how most people are doing the cord DAT - tube or gel?

Hi Mohammed, Did you conduct your AHG tests strictly at 37 C, i.e. prewarm?

The Technical Manual may have some references. Have the doubting staff members review the literature. BTW, if I told my staff that they didn't have to do something like that anymore, they would be doing cartwheels! R1R2

I agree with Mable. We recommend RHIG unless we know, by molecular testing, that patient is a weak D.
