The method comprises entering type(s) of test(s) needed by the user, providing a list of available POC devices to the user based on the type(s) of test(s) needed, based on the list of available POC devices, providing a map to the user showing locations of nearby POC devices with availability for the type(s) of test(s) needed; selecting one of the nearby POC devices by touching the location of the POC device on the map and booking that POC device for the type(s) of test(s) needed at a particular time slot, and communicating the booking to the selected POC device. The selected POC device then blocks that time slot.
Abstract: A method for determining a vertical position of a horizontally extending interface between first and second components is presented. The first and second components are contained in a laboratory sample container in layers vertically separated from each other. The method comprises generating first data, generating second data in the form of picture data of the laboratory sample container containing the first and second components, determining a first probability distribution function in response to the first data, determining a second probability distribution function in response to the second data, and determining the vertical position of the horizontally extending interface depending on the first and second probability distribution functions. The first data depend on the vertical position of the horizontally extending interface. The first and second probability distribution functions assign a probability of the presence of the horizontally extending interface to a vertical position.
