Abstract Six thousand six hundred seventy duplicate pairs of prothrombin time results were collected and analyzed to determine if replicate testing is necessary. The mean, mean difference between duplicates, and mean percentage differences were calculated, as well as the percentage of duplicate values that did not match. The mean percentage difference and the percentage of duplicates that did not match remained relatively constant throughout both the normal and the therapeutic range. Performance of the prothrombin time by single determination results in substantial cost reduction with a minimal increase in erroneous results.

Abstract Throughout this study, an acridine orange staining method was used to differentiate viable from nonviable phagocytized bacteria, and crystal violet was used to quench staining of extracellular organisms. Human polymorphonuclear cells (PMNs) were obtained from blood clots from adults or infants and neonates (capillary clots). The blood clots were then sectioned and overlayed on 2 drops of bacteria. Kinetic studies indicate that contact of 25 minutes is adequate to assure adherence of PMN to the glass, ingestion, and killing of bacteria. The test is fast, discriminating between the phases of phagocytosis, and most suitable for the clinical setting for adults, infants, and neonates.

Abstract Aldehyde fixation produces covaient bonding that tends to mask antigenic sites and therefore hampers the immunohistochemicai localization of antigen. Pretreatment with proteases (most commonly trypsin) is used to expose antigenic sites. Ficin, a wide-range protease of vegetable origin, is a satisfactory substitute for trypsin and can be purchased in a ready-to-use, stable solution. Pretreatment with proteases greatly increases the loss of sections during the staining procedures, but this untoward effect is practically eliminated when poly-L-lysine–coated slides are used.

Abstract Each of 41 donors underwent plateletpheresis on the CS–3000 (Fenwal), 2997 (IBM/Cobe), and V50 (Haemonetics) blood cell separators. Platelet collection efficiency was highest with the 2997. The fewest number of lymphocytes were present in products collected with the 2997. Procedures with the CS#x2013;3000 resulted in the least amount of change in donor ionized calcium levels and in the fewest number of donor reactions. Products collected with the 2997 had the largest volume and had the longest set-up time but shortest processing time to obtain the highest yields. These data may help apheresis services select equipment best suited to the particular needs of their staff, donors, and patients.

Abstract In the clinical diagnosis of anemia, red blood cell indices and related cell counts show distinguishing patterns that are characteristic of different types of anemias. A computer program called the Anema-Graph, developed in BASIC, makes it possible to suggest a diagnosis of anemia based on the pattern recognition ability of the program using the patients' blood cell indices and counts. This program saves valuable time when a patient diagnosis is being made and offers new possible diagnoses that may have been overlooked.

Abstract Faced with increasing educational costs, diminished financial aid, and a need in the professional community for part-time graduate and undergraduate medical technology education, the Department of Medical Technology of the University of Health Sciences/The Chicago Medical School sought to provide a flexible curriculum designed to meet the needs of the fully employed adult learner. A discussion of development and implementation of a part-time graduate program is discussed with emphasis placed on special considerations of the adult learner.

Abstract The purpose of this study was to assess the role of certified (ASCP) medical technologists in the production of quality laboratory results. The quality of laboratory results was represented by the proportion of satisfactory results on the College of American Pathologists (CAP) survey programs summarized into a Laboratory Quality Score (LQS). Data from Illinois state records for licensed laboratories provided the sample. When all tests were considered simultaneously, a significant positive correlation between the proportion of ASCP-certified medical technologists employed in the laboratory and the LQS was found. The strongest relationships were found in the laboratory areas of hematology/coagulation, microbiology, and diagnostic immunology/ syphilis serology. Even in an economic environment that demands cost containment, the quality of laboratory results must be maintained for delivery of appropriate patient care. The study confirms the influential role of certified medical technologists in producing quality test results, especially for tests in which judgment and interpretation are required for accurate reporting.
