FIELD: physics.
SUBSTANCE: method for detecting underfill state in biosensor involves transmitting a test excitation signal into a sample of biological fluid medium, switching the test excitation signal to at least one other amplitude, measuring the test output signal reacting to the redox reaction in the sample, comparing the test output signal with at least one underfill threshold value and detecting underfill state in the biosensor by comparing the test output signal with said at least one underfill threshold value.
EFFECT: invention provides accurate or reproducible detection of underfill in biosensors.
