Abstract

Systems and methods for providing remotely proctored at-home health testing and diagnostics are provided herein. In particular, systems and methods for improving proctor performance by increasing accuracy and reducing proctor time are disclosed. In some embodiments, images and/or video of a patient may be enhanced to aid the proctor. In some embodiments, proctor performance may be evaluated. In some embodiments, proctor time per patient may be reduced by automating one or more steps in a proctored testing process.
