Retrieved Dec 25 2018 from Q Occasionally, we hear complaints from pediatricians that we report too many bands in our manual differentials. Our laboratory adheres to the CAP classification criteria that require seeing a filament in order to call a seg, a seg. If the nucleus is folded on itself and it's hard to see what's underneath, we go with the more mature cell.

This request, although triggered by a physician inquiry, is primarily based on our performance on New York State Cytohematology proficiency testing, where we regularly fall in the upper end of the acceptable range for bands. I have not been able to find a reference for classifying segs and bands that is not based on the CAP criteria. Crackerbox race boats sale. In order to retrain our techs it would be very helpful to cite a reputable source. Any assistance with this request would be greatly appreciated. A Neutrophils dominate the normal adult peripheral blood and may be found in two forms: segmented neutrophils (1,800-7,800/pL) and band neutrophils (0-700/pL). (1) Though traditionally counted as two separate categories, there is growing controversy as to their utility in clinical patient management. (2) The College of American Pathologists defines a band neutrophil (stab or staff cell) as follows: 'Bands are the same size or slightly smaller than metamyelocytes. The nucleus is centrally or eccentrically placed and indented to more than half the distance from the farthest nuclear margin. The nucleus may appear in the shape of a band, sausage, letters C or U, or may be lobulated. If lobulated, the bridge or isthmus between the lobes must be wide enough to have two distinct parallel dark margins with light nuclear material in between.' Other sources define bands in a similar manner. (2,4-6) And yet others offer a more relaxed definition: 'a constriction greater than one half to two-thirds of the nuclear breadth as adequate evidence of lobulation and classify such cells as polymorphoneuclear.' (7) Regardless of the definition or how bands have traditionally been classified, current thinking is that 'a band count is a nonspecific, inaccurate, and imprecise laboratory test.' (2) Furthermore, in a recommendation, the Clinical and Laboratory Standards Institute (CLSI) states that 'the inclusion of 'bands' as a separate category of leukocyte is not supported by medical data.' (8) The CAP Hematology and Clinical Microscopy Resource Committee does not support the idea of using band counts as part of patient management. Yet, band counts in infants under the age of three months are still often requested by pediatricians and neonatologists when dealing with a risk of infection. (9) Reference intervals can vary greatly due to inter- and intra-laboratory variations and the statistical limitations related to cell count sampling (100-200 cells). Though increased presence of band neutrophils may be seen in a variety of diseases such as bacterial and viral infections, inflammatory processes, neoplasms, and other diseases, the WBC and the absolute neutrophil count may serve as a better diagnostic tool. (2,10,11) It should also be noted that when it is uncertain whether a cell is a segmented neutrophil or a band, it is recommended that it be assigned to the former classification.
