Abstract
Apparatuses and for causing a point-of-care polymerase chain reaction and analyzing the polymerase chain reaction at the point-of-care, particularly when unwanted bubbles are present during the polymerase chain reaction, are described herein. In a general embodiment, a device for analyzing a polymerase chain reaction in a fluid sample includes a current source configured to cause the polymerase chain reaction by heating the fluid sample within a target zone, a camera imaging device configured to record a plurality of images of the fluid sample in the target zone while the current source causes the polymerase chain reaction, and a controller configured to (i) distinguish wanted objects in the plurality of images from an unwanted object in the plurality of images, and (ii) determine whether the fluid sample tests positive or negative for a bacteria or virus based on the wanted objects.
