ABSTRACT
Laser-assisted Optical Rotational Cell Analyser LORCA is a precise instrument capable to investigation of aggregations and deformability of erythrocytes. In the paper the action principles of the instruments is presented and the measured quantities such as the aggregation amplitude, aggregation half time, aggregation index and elongation index are defined. A comparison of mean values of those quantities for the control group and groups of patients with obesity (body mass index – BMI > 35), pancreas tumor, myocardial infarction, obstructive sleep apnea, age-related macular degeneration and diabetes mellitus of the type 2 is made.
