Effect of Quality Control on Interlaboratory Performance

[摘要] For 7 months, serum samples reflecting high, normal, and low physiologic values were distributed to five laboratories for sodium, potassium, and calcium analyses. Following recalibration of instruments and required repairs, quality control programs were initiated and additional serum samples were analyzed. The results were collected and statistics calculated to determine improvement, if any, in accuracy and precision. Improvement was demonstrated in some cases.
