METHODS AND DEVICES FOR TWO-STAGE LATERAL FLOW ANALYSIS Russian patent published in 2011 - IPC G01N33/50 G01N33/53 

FIELD: medicine.

SUBSTANCE: method includes introduction of sample into sample hole of the device, the device being adjusted for delivering said sample into lateral flow matrix, which has multitude of varieties of IgE antigens, immobilised in respective positions in result window. Method additionally includes possibility of sample movement along lateral flow matrix through immobilised multitude of IgE antigen varieties into the second position lower on flow from the first position, introduction of liquid buffer into lateral flow matrix for mobilisation of labeled reagent, which is adapted for binding aHTH-IgE-antibody and is dried in lateral flow matrix in position higher on flow from introduction of filtered sample into lateral flow matrix, and possibility of movement of labeled reagent, mobilised by liquid buffer, along lateral flow matrix through multitude of immobilised varieties of antigens IgE into position lower on flow from the first position.

EFFECT: simplification of process.
