Prime Time for Enzymatic Creatinine Methods in Pediatrics

Autor: Cas Weykamp, H. Baadenhuijsen, Christa M. Cobbaert

Publikováno v: Clinical Chemistry. 55:549-558

Background: The literature regarding the nonspecificity of applications of the Jaffe (alkaline picrate) reaction for creatinine is generally outdated. We conducted a specificity study to update the nonspecificity information for current Jaffe and enz

Autor: M H, de Keijzer, R A, Koene, H, Baadenhuijsen, J L, Willems

Publikováno v: Nederlands tijdschrift voor geneeskunde. 143(13)

The anion gap is used to evaluate disturbances in the acid-base balance, in particular metabolic acidosis. Due to the introduction of new clinical chemical techniques and modern analysers the reference range of the anion gap has changed. Clinical che
