FIELD: medical engineering.
SUBSTANCE: device has non-absorbing substrate having hydrophilic target region, which is covered with reagent by applying non-impact micro-drop printing method to produce practically uniform reagent layer. The device is in particular usable for measuring blood coagulation time. Preferential invention embodiment involves determining blood coagulation time by carrying out monitoring of light transition through the target region as the blood sample cover interacts with the reagent.
EFFECT: high reliability of analysis results.
