Abstract
A method and apparatus to estimate the concentration of a non-fluorescent substance (e.g. haemoglobin) in a fluorescent assay by separately estimating the non time dependent alteration attributed to inherent filter effects from the time dependent alteration caused by the assay chemistry. Such a method obviates the requirement for a separate photometric or other measurement thereby simplifying the methodology and associated instrumentation.
