Thank you for your reply. Do you acceptable even though it is a draft guidance?

The latest cdc map/guidelines indicate there is a small risk in Quintano Roo. Cancun and Cozumel are located there. There is no stipulation in the latest guideline regarding urban vs. rural travel. Previously there was a stipulation about small foci near the guatemala and belize borders. Does anyone have a guideline they would be willing to share regarding Quintana Roo? Thank you

Is anyone aware of a ISBT label for leukoreduced red cells from a low volume collection? Thank you

wow. That is quite a story. Congratulations on the investigation!

Currently we defer the donor for 8 weeks after the positive screen if the confirmatory is negative. After 8 weeks the donor is drawn and the testing is repeated. If the screen is positive again we defer permanently regardless if the confirmatory is negative. According the the 1987 FDA letter regarding this it sounds like a donor can continue to attempt to donate as long as the confirmatory continues to be negative (if the screen continues to be positive the units need to continue to be discarded). Thanks for any info you can provide.

What are your deferral policies for HBsAg? thanks, Dana Langsford Marquette General Health System U.P. Regional Blood Center

Are there any restrictions on the use of intended recipient label attached to the blood bag vs. the use of a tie tag?

today i spun cold units at 4200 rpm for 15 minutes. The highest hematocrit I got was 53%??? Does it matter what type of bag we collect it in. We use a 450 ml bag, 100 ml Additive solution and our anticoagulant is CPD. Not sure what is wrong. My RBC volumes after addition of ADSOL were all <350 and my plasma volumes were all 275 or greater. Thanks

I use a Beckman J6 series centrifuge. I have trouble obtaining a hct >55% consistently with our cold units although my plasma and packed cell volumes are good. What type of centrifuge do you use and what spin time and speed do you use. After the additive solution has been added, i mix the unit, strip the collection line, and obtain a sample for hematocrit. We run the sample on a Coulter cell counter. Any suggestions? Thanks

Standards says that the hematocrit of packed RBCs must be <=80%. The technical manual also says (pg.805) that after the addition of additive solution the hct should be within 55 and 65%. What are some of your packed RBC hematocrits? Thanks

We frequently process blood collected from the day before. Our Transfusion Service frequently says that these units have too much plasma still on the units. We obviously don't make platelets from units that have been refrigerated overnight. Has anyone ever calibrated a centrifuge for the purpose of processing cold units and what information are you trying to capture? I am not interested in platelet yields since we do not make platelets from these units. I just need the speed and time to be such that we are expressing the most plamsa possible. Thanks

If anyone has implemented the new Donor History Questionaire, I have a couple of questions. 1) The latest draft guidance for platelets, apheresis says we should not collect platelets from donors taking aspiring and also plavix, ticlid, and non-steroidal anti-inflammatories. How do you now if your donors are taking these since the questionairre doesn't ask a question about medications other than the specific ones listed in the medication deferral list? Have you added a question regarding other medications? 2) Doctor's care. Has anyone added a question about doctor's care in the last 12 months? Any insight would be very helpful. We are going to be implementing this new questionairre in the near future but I was concerned about these issues. Thanks.

What type of validation did you do for the chlorhexidine prep? We are looking at this as an alternative but am a little lost on how to validate it. Any help would be appreciated. Thanks Dana Langsford
