Abstract
Analytes [13] were presented in the Urine Chemistry Survey Program during 1978. These included amylase, Ca, P, Na, K, creatinine, osmolality, total protein, glucose and urea N as regular constituents. Optional analytes included 17-ketosteroids, 17-ketogenic steroids, and vanillylmandelic acid. Certain samples elevated Na, K, Ca, and P concentration to stimulate human disease states, and to test consensus results in ranges heretofore not possible. Serious loss of precision performance was not noted although some methods are noticeably affected. Improvement in interlaboratory precision has slowed as compared with previous years.
