Patent number: 11921272Abstract: Apparatus and methods are described including a sample carrier (22) configured to carry a portion of a bodily sample, at least a portion of the sample carrier being configured to fluoresce, at least under certain conditions. An optical measurement device (24) performs optical measurements upon the portion of the bodily sample that is housed within the sample carrier (22), and at least partially photobleaches an area within the portion of the sample carrier (22) by causing the area to fluoresce. By detecting that the area within the portion of the sample carrier (22) has been photobleached, an output is generated indicating that at least a portion of the sample carrier (22) is contaminated or that optical measurements cannot be performed on the portion of the sample carrier (22), or the optical measurement device (24) is prevented from performing optical measurements upon a sample portion housed within the given portion of the sample carrier (22).Type: GrantFiled: November 12, 2018Date of Patent: March 5, 2024Assignee: S.D.

Publication number: 20230296495Abstract: Apparatus and methods are described for use with an output device, and a blood sample that was drawn from a subject. A microscope system acquires first and second images of the blood sample at respective times. A computer processor determines whether, between acquisitions of the first and second images, there was relative motion between at least one erythrocyte within the sample and at least one entity within the sample, by comparing the first and second images to one another. At least partially in response thereto, the computer processor determines whether the entity is an extra-erythrocytic or an intra-erythrocytic entity, and generates an output on the output device, at least partially in response thereto.
