We have a system called bloodtrack. Basically crossmatched units for named patients and 2 O neg units for emergency use (labelled with dire warning about uncrossmatched red cells) are kept in a locked fridge. To access this fridge the user who comes to collect units has to scan their barcode then the barcode on the blood pack(s). Bloodtrack saves the information regarding personnel, unit details and time removed from temp. controlled storage.
There is an audit form with the emergency units which the medic has to fill in and return to the lab. so that we know which patient has received which emergency unit.
We keep a line segment from these units if case we need to retrospectively crossmatch (eg. for transfusion reaction investigation).
So, in conclusion, we rely on a paper based system to inform us that a specific emergency unit has been transfused to a certain patient.
I wish we could afford BloodTrack.

Hi everyone-
We are a bit late to the game here - we had been keeping our thawed FFP at 24 hour expiration date and now with the Convalescent Plasma build I wanted to have it expire in 5 days - well the reason why we never went to 5 day originally was that it required some sort of FDA registration to do so? Can anyone update me as to the process to convert from 1 day to 5 days other than the obvious LIS build out, labels etc - is there an FDA requirement still? Thank you!
FDA inspectors have told me that they have jurisdiction over all transfusion services. They just choose to restrict themselves to sites that perform certain modifications (e.g. washing and/or irradiating).

We've been converting FFP to TP directly for some time now. All of our thawed units start with a 5-day outdate.

We do this as well. Instead of going to 24 hour plasma at the time of thaw, and then to five day plasma the next day, we go directly to five day plasma at the time of thaw. Any time you relabel a unit is an opportunity to mislabel a unit (product code and expiration date especially), and eventually someone will do that.

30% albumin hasn't been available for years - I think we saw it last in the early 90s.
I don't think I've ever used the Lui Freeze Thaw on a patient. I keep a copy of the ancient procedure around for students.
The Lui Freeze Thaw method is good for demonstrating anti-A, anti-B, and anti-A,B from small samples. We used it to confirm that an infant had ABO HDN. I'm not sure if we still have a procedure for it. I work primarily with the Blood Bank Computer system now.

Why is bovine albumin used as a potientior in a lui freeze elution. Most procedures I have read does not require it. Thanks
It has been eons since I did one of these, but I don't remember using albumin. I looked at a couple of procedures online, and it was not listed as a reagent.

I work at a blood center and I can tell you that though super rare, mislabeling does happen. Not sub-groups, or variants, but actual wrong blood in the wrong bag situations. I have only seen a very small number of these and they always involve the most unbelievable, bizarre, "were they TRYING to mess up" situations. These situations usually result in 2 first time donors having their blood drawn into a bag labeled with one number and the tubes labeled another number, now both bags have the wrong blood/label. First time donors do not have history to catch these discrepancies. I would never suggest the confirmation step at the hospital be removed, especially with electronic XM so prevalent now. I guess it's been at least 6 or 7 years since we had one of these.
I've been active in blood banking for a while, and I've seen just a few of these. Most of the ones I have seen involved two units being swapped. The first one I remember was an AB unit that was labelled as an O. The unit had come in as part of a shipment for our neonatal stock; when we retyped it, we found that it was actually an AB.

I realize what you say is correct Malcolm, but that is what my supervisor called it and that is the way it was reported back in then.
And it is a whole lot easier to say.
By the way, the U stands for Underwood; this is the name of one of the early patients identified with a partial D.

I am told that they work best in environments with moderate to low turnover.

We keep blood on the nursing unit when we have an ECMO. It is in case of emergency decannulation. It is tagged for the ECMO patient and kept in a blood refrigerator on the nursing unit. We check the temperature in the refrigerators every day.

We give Hb S negative rbc components to known sickle patients.

we have SafeTrace Tx. I built modifications for Pgd tested plts that changes the product code and expiration dates of the tested plts.

We had a patient with anti-Jk3. We were able to find units for him once the blood supplier started looking at Polynesians and Pacific Islanders.

WOW, don't see anti-JK3 too often!
Have you already pursued family members and extended family members? Also, is there a ethnic group you may want to screen? We have had some success in the past in our area with Native Americans whom have had some members with a antibodies to a high antigens.
Certainly would want that patient and or other family members start donating and freezing their donations for their and others' future.
Technically, I agree with Mr. Needs approach with trying to resolve your immediate requirements.
Good luck and best wishes for your patient's recovery.

I THINK THE CLOSEST THING IS ANTIGEN TYPING.

We stick with O until we get a second type.

Our system does not allow us to pool across product types, so we treat a reconstituted whole blood unit as two units (RBC and plasma) in one bag. We label with both product codes and both DINs.

I was going to suggest that you check with the manufacturer. If you haven't already, look at the package insert.
