Paper Abstract

Accurate self-testing of coagulation status by patients receiving anticoagulant therapy can reducing the burdensome need for frequent and expensive laboratory testing. We have developed a new smartphone-adaptable optical module that provides multi-functional assessment of blood coagulation status with a drop of blood via a finger-stick draw. The spatial speckle contrast imaged on a smartphone camera through our optical module evolves in time as blood coagulates. Studies using blood samples tested at hematology laboratory in hospital show strong correlation with our speckle contrast results for activated partial thromboplastin time (aPTT) and prothrombin time (PT).
