Establishing ranges of clinical normal limits and comparison with adopted limits for adult population

Abstract

Abstract: It is important to know the normal limits for each test in each laboratory. In most cases the normal limits established by others have been adopted and used as reference values. In view of this an attempt is made in this paper to establish ranges of clinical normal limits for adults. Eight determinations SGOT, SGPT, ALP, BILD, BILT, FBS, UREA, and CREATININE were included in the study. Normal limits were established based on a validated statistical method. Comparision was made with adopted normal limits in use in laboratories. For most tests notable differences in limits, particularly from the side of abnormal values, have been observed which resulted in high misclassification of laboratory test values. [Ethiop. J.
