  1. I agree with Ensis01. Sometimes gel can give a false positive - if there is a problem with the card/well or sample (bit of fibrin, etc) - which is resolved upon repeat and/or tube testing. Otherwise, yeah, if you can explain it = great, group specific (meeting all other policy, of course) If not = O. sandra
  2. Sorry - just saw this reply now. Canadian Blood Services tests all donor units for K. If K negative, the donor end label has K- on it. If K positive, the end label doesn't have any K antigen testing information listed - the K+ status is only embedded in the donor unit phenotype barcode. All donor units are treated the same - so the K+ units are available, as all other units are, but it is easy to select a K- unit for females of childbearing potential and who are on a drug like daratumumab. sandra
  3. Hey Nikki, You planning on an IH-1000 or two IH-500? Or a combination with or without the SAXO? sandra
  4. We require any request for blood component or blood product pickup to have the following: Patient Name Patient MRN (i.e. hospital number) Type of product required Location (for phone requests to send via pneumatic tube system) A sticker or other official paper is not required. The info can even be handwritten - but all is required and it has to be correct. sandra
  5. Same. We don't select K negative units once off the dara. Here in Canada, all our units are K typed by Canadian Blood Services. It wouldn't necessarily be more work to select K neg units, but we feel it isn't needed.
  6. We share an LIS with a couple of other hospitals. We allow those previous blood groups to be the confirmation sample. We have access to a validated computer system that pulls results from other hospital LIS systems and matches using a unique ID (here in Ontario Canada it is the OHIP number). Names/DOB are double checked. We allow those for the second blood group as well. All our labs are accredited. I'm not sure what the difference between using the other hospital result in the LIS vs the other validated computer system would be. Also... my experience has been that blood testing done recently is MUCH more reliable than testing from many years ago - even if in the same hospital. Use of automation and positive patient ID systems has greatly reduced the risk of error. sandra
  7. In Canada, all blood components and blood products (derivatives) require informed consent.
  8. Here in Canada, the same sample can be retested IF the sample was collected using positive patient identification. So, here in our lab, we are super lucky because we have MLA who perform phlebotomy on 95% of the patients (some are nurse collected in the ED and ICU). Our MLA use positive patient identification technology (Mobilab). We allow for the retesting of those samples. Anyone else needs a new sample - which we order for lab collection, thus avoiding the workarounds where a second sample is drawn at the same time as the first but tucked away until needed. We also allow the previous ABO to be from another lab. We have access to blood bank results from area hospitals. If the blood group from our hospital matches another hospital we don't need the restest. sandra
  9. I'm so jealous - all these labs where the KB is performed in hematology! Here ours are done in the BB. To be fair, we are a core lab, so the staff performing the test are the same. I would just rather not own the test and all the competency that comes with it
  10. We have been using a Bio-Rad IH-500 (and a SAXO as backup) for about a year now. Very happy with them. They work with the IH-Com that serves as a command centre for both and as middleware. We also use the antibody software and upload our QC to Unity. (We were manual gel/tube prior). sandra
  11. Thanks Ensis01! I haven't even gotten that far yet - so I didn't know that the concentration of DTT is different :) s
  12. When I was trained (many years ago!) we used +/- for microscopic tube reactions. Now, I encourage MLT to only use the microscope if they are looking to verify a mixed field or rouleaux. I suppose there could be other rare times to use a microscope - like an anti-Sda? But generally - no microscope. But they love the microscope...
  13. I'm also developing a procedure for DTT treated cells. Can I assume that the DTT treated cells can be used to help ID antibodies other than daratumumab without additional validation? I am intrigued by the use of DTT for differentiation between IgG and IgM antibodies but I don't think we will go forward with it here at our community hospital
  14. We do the same as Nikki. If an eluate is needed, an acid elution is done. No LUI freeze on the menu. sandra
  15. Nikki - my calendar says it is 4am to 5:30am here! I hope it is available as a recording! sandra
  16. Is it possible you have someone new who is not cancelling the units properly? s
  17. It's an interesting idea - one motivated I suspect to provide a more attractive product to the hospital? But retyping in the hospital also theoretically covers any errors in donor entry into the hospital LIS. sandra
  18. I've uploaded a Canadian Report from earlier this year that you may find interesting. Pages 11-12 have discussion and recommendations. Some of the discussion includes the following: Unnecessary testing:  Performing mid-pregnancy screens on Rh positive mothers  Testing DATs for all cords, or from all group O mothers or all Rh negative mothers, regardless of hemolysis indications sandra Obstetrical and Pedatric report -COPTN-Survey-Report-2019.pdf.pdf
  19. We have a log book and a white board. The log book is a daily calendar and it is for more date specific items (i.e. order a specific product on that day) The white board is for more general or urgent items - something that doesn't fit on a day or would span over a longer period of time (i.e. shortage of a product). sandra
  20. The reagent we use includes instructions that only specify a positive reaction is required. It does not give a minimum grade. I remember being taught 2+ many years ago, but we now only require macroscopic agglutination. sandra
  21. Same - we report the number and a %
  22. In our lab, the required additional testing is built into our procedures - which is authorized by the pathologist. If we have weak D results or something like an auto-anti-D in an Rh pos person we can send it out without asking for approval. We scan the report we get back into our LIS. I'm in Canada - so the testing is done by Canadian Blood Services at no additional cost the the hospital. sandra
  23. Here in Canada, the CSA standard 10.10.5 states: CSA 10.10.5 A blood component that has been returned to the blood centre or transfusion service shall not be rereleased unless a) for red blood cells, there is at least one remaining sealed segment of integral donor tubing attached to the blood bag or available to the transfusing site. Previously removed segments may be used after confirming that the tubing identification numbers on both the removed segment(s) and the blood bag are identical; b) there is documentation to a. indicate it is being re-released; and b. confirm that it has been visually inspected before release; c) a suitable temperature-monitoring system indicates that the blood component has not reached an unacceptable temperature since being released or, in the absence of a temperature-monitoring system, that the blood component has not been outside of a controlled environment for more than 60 min (measured per occurrence, not cumulatively); and d) the blood bag closure is undisturbed. I know that isn't necessarily helpful for you currently, but this was new in the last revision. Perhaps changes coming soon to other countries? sandra
  24. Here, a temp >1 degree Celsius over baseline AND any other symptom gets an automatic culture. Plus I suppose we would honour any direct request for a culture (not that I've seen that happen).
  25. We do that. Patients who come in through our pre-op program are good for 28 days if they are not pregnant and have not been transfused in the past 3 months. There is a query that must be completed in our LIS to confirm the answers to those questions. Any other patient that is not seen via pre-op is 96 hours. Rationale: patients seen through pre-op have sat down with a nurse or physician prior to their surgery and given an accurate medical history. Translators or family members are present as required for language or any cognitive deficit (dementia etc.). Any other patient? - who knows what their status is. This works very well for us. Sandra
