  1. Criteria for Pathology Review

    Hi kholshoe, I would agree that the slide review criteria is set primarily by the medical director/ pathologist and as each may help to treat varying patient demographics and each pathologist has their own manner of practice, the criteria for the slide review would, indeed, be somewhat subjective. I have practiced in a number of hematology labs with each having their own criteria for slide review based on the practice of the pathologist signing off on the procedure. The establishment of the criteria seems to be mostly a top down decision with some influence by the supervisors who are closer to the actual work flow. In other words, the work flow of the lab, and technical staff practicing, may have some influence on this decision as well. I hope this helps.
  2. Strong Cold Agglutinins and CBC results

    Thank you for the info kimannez. I was not sure if the strong cold agglutinin would alter the distribution of rbc's prior to the lysing step significantly enough as compared to the diluted aliquot specimen. But I can see where a "harsh lyse" would be more useful. Can I ask, what instrument was in use for this testing?
  3. Strong Cold Agglutinins and CBC results

    Hi Kimmannez, I was curious to know what your acceptable range is between the neat hgb result and the diluted hgb result. Given that the strong cold agglutinin would significantly alter the rbc distribution of the neat specimen as compared to the diluted specimen my guess is that your range is broad. How was this range established and do you know of any references? Thanks for any info.
  4. anion gap reference ranges and to use K+ or not

    Scott, do you know the reason why the K result is considered negligible in the anion gap calculation? Is it because the K result is usually a much smaller number in comparison? And if this is the case then when the anion gap is at the border of the range, would the K result not make a difference there, at least numerically, but with questionable clinical relevance?
  5. Chronic Reactive Lymphocytosis

    Thank you Scott. Multiple Myeloma is what I was thinking of.
  6. Chronic Reactive Lymphocytosis

    If these cells are Lymphoma cells, and if I am not mistaken, would a follow-up Urine Electrophoreses be in order to detect Bence/Jones proteins?
  7. BB saline

    Hi kblewett, Happy New Year. While I am no expert I would say, from a practical perspective, that I can not see how throwing away 90% of a perishable product, of the larger volume size, would be less expensive then buying less of the smaller volume size of the same product at higher cost initially but would allow for use of greater volume of the bottle, once opened, and sustain a longer shelf life, with the exception of unexpected storage environmental mishap, enabling you to absorb the higher cost. In other words, buy less quantity of the smaller volume size at an initial higher cost, but be able to use near 100% of the volume and because it is the smaller size you would be able to store it, unopened, for a longer period. These to benefits may help absorb some, or all, of the higher cost. I hope this helps some.
  8. To BB (ASCP) or Not

    I did the same except the other department for me was Hematology. I realized after taking the BB ASCP and passing it the first time out that what helped me the most was my practical experience and not so much book study. As far as concern as to whether I should take the exam or not, I was concerned with any impact on my current position at the time if I did not pass this exam; but I am happy to say that those concerns were not warranted at all. So you should take this exam and any other exam that you are qualified to take.

    I just answered this question. My Score FAIL  
  10. Stago Compact Max vs ACL Top 350

    Hi Kimg, I have used both for many years. The bench top Stago appears to be a more reliable instrument. The means by which it tests the plasma, movement of magnetic ball in reaction cup stops when clotting occurs, gets around most HIL (Hemolysis, Icterus, Lipemia) issues, which is a big plus. The only draw back, for some, is the loading of specimens one at a time. The TOP instrument uses specimen racks that hold ten specimens each and have eight rack bays for loading; so one can load eighty specimens consecutively. However it's means of detection is spectrophotomic, light transmittance I think, which can be altered do to HIL; the degree of which differs for each assay.
  11. Not withstanding the need for completing this vital work by chosen means available, if the transfusion of this patient becomes a life or death issue, as determined by the patient's physician, then the patient's physician would sign for uncrossmatched ABO/Rh compatible PC's.
  12. Return of issued products

    We go thirty minutes although it seems well known that the rbc unit will exceed 10C well prior to thirty minutes.
  13. Return of issued products

    Does this unit have to be reissued or transfused before this new four hour expiration?
  14. FDA reportable Question

    Is there a way to ask the FDA directly? Does the FDA offer accessible public information as to the specifics of what is and is not reportable?
  15. Beckman DxH

    Hi Scott, I guess you have a better service package than what I currently work with. But you say that you run one level of control each shift and does that mean that you never have a need to run all three levels of QC consecutively in a 24hr period? How long have you had your DXH's? As far as the slide-maker-stain is concerned, I have worked with both Beckman/Coulter and Sysmex instruments and from my experience the Sysmex SMS is a better and more reliable choice. I had the opportunity to learn about the new line of Sysmex instrument in a one-on-one, four hour lesson with a technical rep and I think that the Sysmex is the better of the two instruments. I in no way connected to Sysmex or DXH from a sales perspective or any other perspective other than being an end user. From the direct experiences I have had with both of these instruments I think that the Sysmex comes out on top.
