ASSAY AND SENSING MEANS FOR DETERMINING ANALYTE

摘要

Lancet (384) by which a fingertip is pierced by a sharp finger pricking means (474) which is connected to a retractable trigger means (468), memory means (458) in force transmitting relation with the trigger means in order to penetrate into and retract from a finger to acquire a droplet of blood. Further the invention relates to a device for an assay wherein a mercury substance released from a free or bound tracer is caused to eventually amalgamate with aluminum, and the presence and/or amount of analyte is determined by changes in the metal resulting from the eventual amalgamation which may be measured electrically or by other means. The invention also relates to novel lancets, analyte sensors and sensor packets and related methods.
