Clinical chemists as clinical consultants

One of AACC's goals is to promote the role of the clinical chemist as a consultant on questions of laboratory clinical practice such test ordering, test selection, result interpretation etc. in the context of individual patients. There are many opportunities to promote what we do such as going on rounds, attending clinical conferences, and generally getting visibility outside the lab as content experts in the ever-expanding domain of lab diagnostics.So my hope in starting this thread is to generate discussion of this topic and learn about what my colleagues are doing in their institutions. What are the limitations to expanding the role of the clinical chemist, what can be done to overcome them? Are we near a point where information science can help us filter through the deluge of data that we ourselves generate every day? Is the lack of reimbursement a stumbling block? Is this beyond the comfort zone? What do you think?

Ultracentrifugation procedure and validation

Hello, I have the impression that a lot of institutions ultracentrifuge/air fuge lipemic samples for chemistry tests. In our system, a special comment is appended to results from an ultracentrifuged sample. I wonder whether anybody can share a validation procedure for the practice.;I am also curious about the list of analytes that can undergo the ultracentrifugation process. At one lab in our system, the list includes CMP, Amylase, D bili, Cholesterol, CK, CRP, HDL, Iron, Lipase, LDH, Magnesium, Phosphorous, Transferrin, Triglycerides and Uric acid. Contribute online

Specimens frozen in gel separator tubes during transport

This question concerns specimens collected in gel separator tubes and spun on site, then transported to a central laboratory. In the upper midwest, it is not uncommon to receive specimens with frozen or slushy plasma/serum (on top of the separator gel). We evaluate these events case by case, but depending on circumstances, we sometimes do proceed with testing if the specimen meets these criteria: 1. Gel barrier is intact (no visible hemolysis and below HIL threshold) 2. Plasma/serum is removed from tube and respun. 3. Test ordered is not for a drug level. 4. A frozen serum/plasma specimen would otherwise be acceptable for the test(s) requested. If anyone has a policy/criteria for accepting serum/plasma specimens that were frozen on gel, please share with us if you can. We are also interested in whether you use a disclaimer when reporting results. Reply online
