Abstract:
1. A method for analyzing at least one constituent of a biologic fluid sample quiescently residing within an analysis chamber, and which sample is mixed with at least one colorant that is operable to reside within the constituent and emit fluorescent light upon exposure to predetermined first wavelengths of light, the method comprising the steps of: illuminating at least a portion of the sample containing the constituent at one or more first wavelengths for a period of time; periodically imaging the at least a portion of the sample, including producing image signals, which signals are indicative of fluorescent emissions from the sample; determining one or more fluorescent emission values using the periodically produced image signals, and a rate of change for the fluorescent emission values between a plurality of periodic image signals; and analyzing the constituent using the determined rate of change of the fluorescent emission values for the constituent.
