Abstract
Methods and apparatuses for determining whether a fluid has been introduced into an assay measurement apparatus involving delivering a fluid to a surface of a resonant device. The methods also involve monitoring an electrical signal output by the resonant device, wherein properties of the electrical signal vary based on physical properties of the fluid in contact with the surface of the resonant device and determining if the electrical signal output by the resonant device satisfies a predetermined condition indicative of the presence of the fluid.
