We use Immucor for our reverse (back) type and the package insert indicates that we need to confirm the reactivity of the A1, A2, and B red blood cells, not the negative results. So, we only daily QC that they are reactive.

No Ensis, I'm only asking if there is a specific time between the drawing of the sample and the date of injection mentioned in any standards anywhere. Historically, we have always said it had to be 14 days between sample draw and injection. I'm just wondering if there was a reason. Thanks for your response.

Thank you Mabel. I understand the why of RhIg. I just wasn't sure if 30 days was an acceptable amount of time to have the sample for or if there was a worry of other antibody formation between the time of draw and the time of injection. Perhaps I am just not explaining myself well enough. Thanks for your response.

Does anybody know if there is documentation or requirements anywhere indicating the length of time a sample is good for on an Rh Negative pregnant woman who requires her 28 week RHIG injection? We have always said the injection must be within 14 days, but as with many other things, I'm not sure if there is a scientific reason for this or if it is one of those "That's the way it's always been things" Thanks for your time

I'm very glad you shared this wonderful news with us. We may have never met but you have helped countless people including me in my short time as a member of this forum. I am very excited for you and hope to one day be able to meet you in person. Congratulations! Please don't ever leave this forum, it wouldn't be the same without you. Nikki

　This is the Canadian Standard: A little vague....... 　 10.6.1.3 To provide ABO- group-compatible red blood cells, there shall be at least two determinations of the recipient’s blood group on record: one from a current sample and the second from the recipient’s previous records; 　 testing of a separate sample collection; or retesting of the same sample where positive patient identification technology was used at the time of sample collection. Note: Positive patient identification technology refers to a computerized system that uses a barcode, radio- frequency identification (RFID), or another electronically readable element on a patient’s identification band to confirm identity.

Poly Specific AHG is less expensive.

I eat cookies as much as possible AuntiS. Wish I could have been at ISBT.

And if you were going to be there Malcolm, I would have changed my plans around and driven 4 hrs to Toronto, just for the opportunity to shake your hand and the ability to say, "I met Malcolm Needs"

Always the BIG question. Was it drawn properly? I think you answered your own question there.

To further confuse the issue the National Advisory Committee in Canada has now said that as long as the unit of blood is returned within 60 minutes, temperature doesn't matter. This is from the Canadian Society of Transfusion Medicine Standards 5.8.7 Return of Blood Components and Blood Products 5.8.7.1 Blood components may be returned to the TS inventory if the following conditions have been met and documented: a. visual inspection of the blood component is acceptable b. the bag is intact, including ports c. at least one sealed segment of integral donor tubing is attached on red cell components. Alternately, an identified segment must be available to the transfusing site. d. the temperature of the blood component is acceptable or the blood component has not been out of the controlled environment for more than 60 minutes from the time of issue (per occurrence, not cumulative).10.10.2/10.10.5/11.4.7 We find this standard rather vague. What is the acceptable temperature and what would standards for our Quality Audit (like your AABB audits) consider a controlled environment? From what I have learned this was a very rigorous testing process at extreme high and extreme low temperatures and there was never any bacterial issues if the unit was returned to the refrigerator within 60 minutes regardless of the temperature of the unit upon 'return'.

I'm so glad I live in Canada. We don't bill for anything, we just do it.

Thank you Malcolm. I knew you would come through on this one. I am going to find that book straightaway.

I have to ask because we are getting pushback from our Pathologist about the clinical relevance of this very outdated test. Does anyone still perform Cold Panels to identify and determine the difference between Anti-H, -IH, -I, or do you just call it a cold antibody, warm the plasma and call it a day? Does anyone know anything about a hemolytic cold antibody? Thanks in advance.
