Here is a question from colleague, friend, and frequent contributor Larry Brace, PhD, Edward Hospital, Naperville, IL : Our (years-old) phlebotomy policy says to wait 4 hours after dialysis before venipuncture unless a doctor approves the draw. It makes sense but we can’t seem to find a reference. Can you suggest any? Also, is this policy pretty much standard?

From Heather DeVries, Indiana University: Greetings George! The labs within our system have been discussing our reportable range for D-dimers. Our vendor's stated limit is beyond what calculates from our AMR and maximum dilution. We are debating changing our reportable range to what we calculate, and stop using the vendor's limit so that we truly are within CAP regulations. What do other systems do? Would they choose to stay with the vendor's limit and refer to them if questioned by CAP, or would they change to what calculates out mathematically? I can give specific numbers if this doesn't make sense! Thanks, Heather

Dear Fritsma Factor, I am a hematopathology fellow evaluating the following patient for thrombocytopenia. History and laboratory results are listed in detail below. We have encountered a situation where the patient develops platelet clumps within citrate tubes but not in EDTA. I have found only limited information regarding this phenomenon and was wondering if anyone has encountered this during their practice or has references relating to this problem. Thank you for your assistance.
