Plasma fibrinogen, cholinesterase activity, and anemia: utility of fibrinogen in multiphasic screening and in assessing the activity of diseases.

I present the general pattern relationship between (a) plasma fibrinogen and cholinesterase activity and (b) plasma fibrinogen and hemoglobin, in 250 and 310 hospitalized adults, respectively. Although responses of cholinesterase were often unrelated to fibrinogen, when its activity in plasma was depressed, above-normal fibrinogen concentrations were present in about 90% of the subjects. Further, despite the observed independence of hemoglobin and fibrinogen concentrations, whenever frank anemia was present (hemoglobin less than 110 to 120 g/liter), hyperfibrinogenemia was also present in about 75-85% of such anemic patients. Thus, these studies affirm that fibrinogen determination would be an appropriate component of tests on hospital admission and also that hyperfibrinogenemia is a very sensitive "acute phase" reactant, and an important reaction for gauging the course of numerous disorders.

Improved biuret procedure for routine determination of urinary total proteins in clinical proteinuria.

This communication describes and evaluates an improved routine methodology for quantitating clinical proteinuria. Based on investigations of Piscator and of Savory et al., a modified Tsuchiya's reagent (ethanolic HCI-phosphotungstic acid) is used to precipitate proteins at 56 degrees C, followed by biuret spectrophotometry at 540 nm. The accuracy of the proposed procedure was assessed by comparisons with results obtained by using an ultrafiltration membrane that retains solutes with an average molecular weight in excess of 10 000 for separating of urinary proteins before they are measured with the biuret reaction. Precision of the method (coefficient of variation) is typically 2-3%.
