We will not process haemolysed samples from A/E but phone them and ask for a re bleed. This serves several functions. The retake the sample early rather than waiting for half the results to be done, saving up to 2 hrs in their process, review who took the blood and retrain. By the second week of new SHO's starting we have very few haemolysed samples.

Having examined the tip of a venflon, the plastic is exceedingly flimsy, and would to my mind allow collapse of the tip under vacuum or flexion of the arm. Transfer of blood from syringe to vacutainer via original needle is also a culprit. This seems to be standard so-called 'training' among doctors, and it is hard to de-train them in spite of H&S and sample quality persuasions. A properly observed study needs to be undertaken with collection of real data to include : +/- venflon Location of venflon on arm Who took blood (really) +/- syringe +/- needle into vacutainer I found that many people were unwilling to admit to reality of practice which negated the findings - hence observed status required rather than self-reported. with best wishes Richard Richard Mainwaring-Burton Consultant Biochemist Queen Mary's Hospital Sidcup, Kent 020-8308-3084 -----Original Message----- From: Jordaan Marieke [mailto:[log in to unmask]] Sent: 08 February 2007 17:05 To: [log in to unmask] Subject: Haemolysis in blood samples The large % haemolysed samples that we receive from our A&E Department came under discussion again recently when we introduced the use of the Haemolysis Index on our routine Biochemistry analysers to reject tests that are affected by haemolysis to a significant degree. We would be very interested to know what the experience is elsewhere, since it is our impression that our A&E is not unique in this respect. Has anyone done comparisons with samples collected under other circumstances and/or by phlebotomists? If I receive a number of replies, I'll collate the results for the Mailbase.
