![]() ![]() Most laboratories relied on external sources to establish reference intervals for pediatric patients. Results.-Approximately half the laboratories reported conducting an internal study of healthy individuals to validate reference intervals for adults. Objectives.-To determine (1) methods used by clinical laboratories to establish reference intervals for 7 common analytes, (2) variation in intervals, and (3) factors that contribute to establishment of “outlier” intervals.ĭesign.-One hundred sixty-three clinical laboratories provided information about their reference intervals for potassium, calcium, magnesium, thyroid-stimulating hormone, hemoglobin, platelet count, and activated partial thromboplastin time. Context.-Standards have been developed for establishing reference intervals, but little is known about how intervals are determined in practice, interlaboratory variation in intervals, or errors that occur while setting reference intervals.
