  • STABILIZED CHOLINESTERASE SUBSTRATE SOLUTION
    Publication number: 20070178546
    Abstract: The present invention relates to the use of a polar organic solvent for the stabilization of a cholinesterase substrate solution, wherein at least one substrate is stabilized by at least one species of a polar organic solvent in a buffered solution, and to the use of said solution for determining the activity of cholinesterase in a sample. Also within the scope of the present invention is a stabilized cholinesterase substrate solution for determining the activity of a cholinesterase in a sample, wherein at least one substrate is stabilized by at least one species of a polar organic solvent. Furthermore, the invention relates to a method for determining the activity of a cholinesterase in a sample, as well as a kit for determining the activity of a cholinesterase in a sample and a kit for conducting a method for determining the activity of a cholinesterase in a sample.

  • Methods for determining an analyte in a plasma or serum sample which may be contaminated with interfering substances resulting from hemolysis
    Patent number: 6268167
    Abstract: In order to analyze a medical sample while avoiding error contributions due to hemolysis, prior to the main reaction for a component present in the sample, a pre-reaction is produced and measured by which the degree of hemolysis in the sample is determined and the result of the sample to be determined that is subsequently obtained is corrected by this error contribution using the relationship (correlation) that has been found between the degree of hemolysis and the error contribution.
