Abstract

A medical testing machine provides improved recall and display of the outcomes of tests performed by the machine. Test outcomes and other information are stored in mass storage directly accessible by the medical testing machine. In one aspect, outcomes of tests relating to a particular patient may be recalled. The system may be especially useful for tests that may be performed multiple times for a particular patient over a period of time, for example testing for HbA1c hemoglobin levels in diabetes patients. According to another aspect, the medical testing machine may store an accession number for each test outcome, and may enable a user to display as a group test outcomes having the same accession number. The system may store further information and associate it with particular test outcomes, for example calibration information. The system may also store a set of rules under which each test instance was run.

8. The medical testing machine of claim 7, wherein the test outcomes having the same accession number are shown in the group on the electronic display regardless of whether one or more of the grouped test outcomes would otherwise be omitted from being shown on the electronic display by a data filter in place at the time the user interface control is actuated.

9. The medical testing machine of claim 1, wherein the computerized retrieval system enables multiple levels of detail to be shown about each test instance outcome.

11. The medical testing machine of claim 10, wherein the stored state information includes a set of rules used to evaluate test outcomes for validity.

12. The medical testing machine of claim 11, further comprising a user interface control that causes to be displayed, for a particular test instance, the rules in place at the time the particular test instance was run.

13. The medical testing machine of claim 1, further comprising an electronic display, wherein during a particular test instance, an animated counter counts down the time remaining until the test is completed.

14. The medical testing machine of claim 13, wherein the electronic display further shows a rack number and position within the rack of a container from which media was extracted for running the particular test instance.

15. The medical testing machine of claim 13, wherein the electronic display further shows levels of consumable materials remaining in the medical testing machine.

16. A medical testing machine, comprising:

an input location, an output location, and a vial handling mechanism that moves vials of media sampled from patients from the input location through the testing machine to the output location;

an extraction mechanism that extracts the media from each vial in turn for testing;

a testing system that performs a medical test on media sampled from patients, each test instance having an outcome, wherein the testing system comprises a high performance liquid chromatography system including a column holding a stationary medium, the high performance liquid chromatography system separating components of the sampled media as the sampled media flows through the column, and the high performance liquid chromatography system including a sensor that senses indications that the separated components are passing the sensor, and wherein the sampled media is blood and the test measures the level of HbA1c hemoglobin in the blood;

a reader that obtains, for each of a plurality of test instances, an accession number of the particular media sample by reading the accession number from a container that holds the media;

a processor that receives the output of the sensor and determines the outcome for each respective test and that causes each test outcome to be stored in a mass storage memory in association with its respective accession number; and

a computerized retrieval system that enables a user to specify a particular accession number and cause the computerized retrieval system to display as a group all of the stored test outcomes having the same accession number.

17. The medical testing machine of claim 16, wherein the test outcomes having the same accession number are displayed as a group regardless of whether one or more of the grouped test outcomes would otherwise be omitted from being displayed by a data filter in place at the time the group display is requested.
