A previous study indicated that the API 230E system can identify coagulase-negative Staphylococcus species. A study was devised to evaluate the use of the API 20E system for this purpose. Because of the current interest in Staphylococcus saprophyticus the relationship of the API 20E results to novobiocin susceptibility was also examined. One hundred forty-nine isolates of coagulase-negative staphylococci from urine cultures were tested with the API 20E system. The identification of 49 isolates was confirmed by Kloos and Schleifer method. We found that the routine API 20E system did not provide more information than novobiocin susceptibility studies alone, and that there was good but not absolute correlation between novobiocin resistance and identification of S. saprophyticus.

The Beckman Instruments' Automated Immunochemistry System, the Auto ICS is a fully automated version of the ICS. This evaluation examines several analytical and cost parameters for five representative assays: IgG, IgA, IgM, phenytoin, and phenobarbital. Correlation with more established methods was excellent, with the coefficients of correlation being 0.9880, 0.9948, 0.9862, 0.9812, and 0.9618 respectively. Intra- and interassay precision was on a par with other immunoassays, with CVs varying from 1.8% to 9.5%. Linearity of each assay was verified. The instrument can be cost-effective, if the simultaneous assay feature is used on batches of at least six samples. The instrument requires very little operator maintenance.

Red cell distribution width (RDW) on the Coulter S-Plus has many limitations. Normal values (mean +/- 2 SD) were found to be sex dependent: 10.7 +/- 2.4 for males, and 9.8 +/- 1.8 for females. These ranges are broader than the normal range of 10.0 +/- 1.5 given by Coulter. When these broader ranges were applied, none of 29 patients with iron deficiency anemia showed an elevated RDW. Furthermore, a decrease in RDW with room temperature storage was observed and may contribute to erroneous results. The Coulter S-Plus RDW may not be as useful in quantitating anisocytosis as other methods of measuring the dispersion of the red cell volume histogram.

When the ASMT Board of Directors approved the conduct of a new laboratory management survey, they believed that the data from the survey would have value to the Society and its constituents. Indeed, it did. These data illustrated to federal health policy makers just how much of a role nonphysician clinical laboratory practitioners play in laboratory administration and day-to-day management. The results of this survey were extremely valuable to ASMT during recent federal regulatory and legal proceedings regarding the role of clinical laboratory scientists in laboratory services delivery and medicare payment policy for hospital clinical laboratory services.
