Abstract: Methods and systems are provided for verifying results of a self-test by a subject using a test kit. The subject's identity may be verified, for example using AI-assistant facial recognition and/or data obtained from scanned government issued documents of the subject. Images obtained while the test is conducted may be used to determine if the test is conducted properly and images obtained of the completed self-test may be analyzed to determine the test results. Test results, verified as belonging to the subject and having been correctly performed, may be uploaded to a remote database as part of a health “passport” program.

Abstract: A test tube may include: an annular body having an open first end, a closed second end, a longitudinal surface extending between the open first end and the closed second end and enveloping a hollow interior of the annular body and a central longitudinal axis; wherein the longitudinal surface of the annular body may include: a first longitudinal portion that may include the open first end of the annular body and having a substantially circular cross-section; and a second longitudinal portion that may include: a first longitudinal side having a substantially circular-arc cross-section; and a second longitudinal side tapering in a longitudinal direction of the annular body towards the closed second end of the annular body.

Abstract: A device for safe storing and expelling of a liquid solution, including: an annular body having a proximal portion and a distal portion and including a transverse member connected along its circumference to an inner lateral surface of the annular body between the proximal portion and the distal portion of the annular body; and a liquid tight piston fitting tightly and movable within the proximal portion of the annular body, wherein the piston includes one or more longitudinal members longitudinally protruding from the piston into an interior of the proximal portion of the annular body, and wherein each of the one or more longitudinal members includes a sharp end to cut the transverse member of the annular body when the one or more longitudinal members being pushed against the transverse member of the annular body.

Abstract: A test tube including an annular body having an open proximal end and a closed distal end, and an longitudinal member in a distal portion of an interior of the annular body, the longitudinal member is substantially parallel to a central longitudinal axis of the annular body and is connected to an internal surface of the distal portion of the annular body.
