Abstract
A method for studying whole blood clotting that includes irradiating a specimen with light and recording light reflected into the hemisphere of the irradiating beam. The time course of reflected light intensity is divided into distinct regions, each of which is fit with a mathematical formula. The parameters from these formulas are used to assign values to each specimen. The assigned values identify disease states and quantify the effects of drugs on clotting.
Claims10
A method for studying whole blood clotting comprising the following steps:
- irradiating a clotting specimen with a beam of light and measuring a time course of intensity of the light reflected from the clotting specimen;
- dividing the time course of reflected light intensity into distinct regions;
- fitting each region with an appropriate mathematical formula in order to obtain parameters;
- using the parameters obtained from curve fitting to assign values to that specimen.
