Abstract

A diagnostic analyzer system includes a linear track, at least one pipetting device, and at least one diagnostic module. The linear track includes a pre-treatment lane disposed parallel to at least one processing lane. The linear track moves reaction vessels, containing samples, held by the pre-treatment lane and by the at least one processing lane. The pre-treatment lane pre-treats the samples in the reaction vessels of the pre-treatment lane. The pre-treatment lane is not connected to any diagnostic module for testing the samples in the reaction vessels of the pre-treatment lane. The at least one pipetting device transfers the pre-treated samples from the reaction vessels in the pre-treatment lane to the reaction vessels in the at least one processing lane. The at least one diagnostic module is connected to the at least one processing lane for testing the pre-treated samples transferred into the reaction vessels in the at least one processing lane.

First claim

The invention claimed is:

1. A method of testing using a diagnostic analyzer comprising:
moving a linear track, comprising a pre-treatment lane and at least one parallel processing lane, thereby moving reaction vessels containing samples held by the pre-treatment lane and by the at least one parallel processing lane;
pre-treating the samples in the reaction vessels of the pre-treatment lane without diagnostically testing them;
pipetting the pre-treated samples from the reaction vessels in the pre-treatment lane to the reaction vessels in the at least one parallel processing lane; and
subsequently diagnostically testing the pipetted pre-treated samples in the reaction vessels.

2. The method of claim 1 wherein the moving the linear track further comprises incrementing the pre-treatment lane and the at least one parallel processing lane in the same increments as the linear track moves.

3. The method of claim 1 wherein the pre-treating the samples in the reaction vessels of the pre-treatment lane further comprises adding reagents to the samples held in the reaction vessels of the pre-treatment lane when the linear track is disposed in one location, and subsequently moving the linear track into advanced locations thereby incubating the samples with the added reagents in the reaction vessels of the pre-treatment lane as the linear track moves.

4. The method of claim 1 wherein each of the pre-treatment lane and the at least one parallel processing lane comprise a plurality of slots in the linear track, and further comprising holding the reaction vessels within the plurality of slots.

5. The method of claim 1 further comprising pipetting the samples into the reaction vessels of the pre-treatment lane and into the reaction vessels of the at least one parallel processing lane using at least one sample pipettor.

6. The method of claim 1 further comprising pipetting reagents into the reaction vessels of the pre-treatment lane and into the reaction vessels of the at least one parallel processing lane using at least one reagent pipettor.

7. The method of claim 1 wherein the pre-treating the samples in the reaction vessels of the pre-treatment lane further comprises pipetting reagents into the reaction vessels of the pre-treatment lane using a reagent pipettor only dedicated to the pre-treatment lane.

8. The method of claim 1 further comprising pipetting reagents into the reaction vessels of the at least one parallel processing lane using at least one reagent pipettor only dedicated to the at least one parallel processing lane.

9. The method of claim 1 further comprising washing some of the reaction vessels of the at least one parallel processing lane by actuating at least one magnet, to bind materials contained in reagents in those reaction vessels, and by using at least one washing pipette, and further comprising selectively not-washing other of the reaction vessels of the at least one parallel processing lane by not actuating the at least one magnet, to not bind the materials contained in the reagents in those other reaction vessels, and by not using the at least one washing pipette.
