Title Components of variability in blood cholinesterase assay results.
Bibliographic information Apr. 1976, Vol.18, No.4, p.242-244. 3 ref.
Abstract Use of blood cholinesterase as an index of organophosphate pesticide exposure presents the problem of variability among individuals and from day to day. This article describes attempts to use commercially available lyophilised control sera as laboratory standard. However, results showed that the control sera used cannot serve as laboratory controls for red blood cell enzyme essays, and that they are unsatisfactory for determining day-to-day variability. It appears that different factors account for daily variability in plasma and red blood cell assay results.
