  1. What are your issuing policies regarding issuing products with regards to product / specimen outdate? Let's say the specimen is going to expire at midnight, the red cell is still good for a couple of weeks, will you issue the product at 11:45pm knowing they will not infuse it before the outdate of the specimen? Let's say you have a specimen that is good for a couple more days. The patient requires a washed platelet. It only has a four hour outdate from the time you start washing it. It's going to outdate in 10 minutes, do you still issue it? Now think of this with the mindset of issuing hundreds of products a day, so you can't work closely with the nurse who requested the thawed cryo to ensure they infuse it before the 6 hour limit.
  2. Gel testing case

    Wild guess here, but did she get RhIG somewhere else?
  3. FDA reportable events

    It's very easy (and preferred by FDA) to do it online. https://www.accessdata.fda.gov/scripts/cber/CFApps/Login/Index.cfm?CFID=40907533&CFTOKEN=d53320b604cd5b33-CA2F5DED-DE8D-E592-8495BFDE2A8C4673 The form can be found here: https://www.fda.gov/BiologicsBloodVaccines/SafetyAvailability/ReportaProblem/BiologicalProductDeviations/default.htm
  4. Liquid Nitrogen Freezer

    We have LN2 here, we used to have a lot when we processed bone marrows. LN2 won't consume oxygen, it will displace it with nitrogen, which already makes up most of the air we breath. If it's going to be stored in a tiny room, you may want an O2 sensor. Our storage unit and supply tank are in our lab. We've never had an issue. The supply tank is usually pretty big and needs to be replaced regularly. Who will be responsible for the tissue? That's what worries me the most.
  5. Return of used blood

    Yikes, can't imagine. We issue about 25k red cells a year. I have no idea where we'd keep the returns. We save a segment.

    You're very welcome. And there's no Dr in front of my name.

    I suspect it does not matter. For the filtering, you need to follow the manufacturers instructions from the timeline for filtering. Most require the product to be filtered early in its life. If it were me, and this is based on preference, not any rules, I would: Filter Irradiate Wash Filtering is likely required early in the products life, irradiating releases potassium, washing will help remove some of that potassium.

    Filtering is to remove white blood cells. They are not useful in transfusion and often cause transfusion reactions. Irradiating "inactivates" the white cells by destroying the DNA within the cells and preventing them from engrafting in the recipient. Washing removes plasma proteins, these can also cause transfusion reactions. http://www.aabb.org/resources/marketplace/Documents/Primer.pdf I'm not sure, possibly, but unlikely.

    Most leukoreductions systems have times limits. You want to get as many of the WBCs out as soon as possible to prevent them from breaking down and releasing cytokines. I would see what your manufacturer requires for leukoreduction. Once it is washed, it is an open system and only has a 24 hour expiration. You could wash / irradiate in either order. Irradiating will release potassium from the cells, but even if you irradiate after washing, the release during that 24 hour period will be minimal. Can you sterilely dock on the bag instead?
  10. FDA 30 minute rule

    We have these. https://www.hampshirecontrols.com/rapid-response-temperature-verification-system.htm
  11. FDA 30 minute rule

    There is no 30 minute rule, I do not believe there ever has been. An old AABB Accreditation Requirements Manual referenced it once. I do not believe anyone supports this any longer. We validated a time to return products in our organization. We have recently changed our policy to using a Temp Check to measure each red cell upon return.
  12. FDA reportable events

    @John C. Staley, this may be true, but the FDA does actually review each file. They notify us a couple fo times a year that an event is not reportable.
  13. Pooled Cryoprecipitate

    We get ours pre-pooled from ARC. Far too much QC needed to do it in house. Also, I your LIS may not play well with a mixed ABO.
  14. FDA reportable events

    Many variables there, might be hard to compare. We transfuse about 35k products a year and have a small donor center. We send FDA 50 - 75 reports a year.
