Development and evaluation of a lateral flow-based portable optical system for determination of the pregnancy status of dairy cows

Our objectives were to develop and evaluate an inte- grated system consisting of a lateral-flow immunoassay (LFIA) and an electronic portable imaging device for de- termination of pregnancy status of cows based on plasma concentrations of pregnancy-specific protein B (PSPB). Experiment 1 was conducted to test the performance of the LFIA for PSPB (PSPB-LFIA) whereas experiment 2 was conducted to evaluate the performance of the inte- grated system including both the LFIA and imaging de- vice....
