Abstract
A pipettable detector comprises an aqueous suspension of particles which are essentially insoluble in a sample of a body fluid containing at least one target ion analyte of interest, the particles having uniformly distributed therein target and indicator ionophores which may be present in the same molecule or separate molecules. The indicator ionophore is capable of giving rise to a detectable signal following complexation of the target ionophore with the target ion from the sample. In a method of detecting an ionic analyte of interest in the sample of a bodily fluid, the sample is contacted with the detector. The indicator ionophore gives rise to a detectable signal following complexation of the target ionophore with the target ion from the sample, and the signal is then detected.
