Problems solved by technology

On the one hand, this is time-consuming, and on the other hand, there is a risk of human error, and thus samples in a mixed state may not be identified in time in some cases (e.g. due to inattention)

Embodiment Construction

[0080] Figure 1a to Figure 1d Shown is a sample tube 10 having various samples 12 accommodated therein. The samples 12 each have one or more phases, wherein in the case of multiple phases the corresponding phases have different phase types. Explicit designations such as "phase" or "type of phase" are generally omitted below in order to improve readability. Instead, the following generally only specifies the corresponding phase type.

[0081] Figure 1a A sample tube 10 is shown with a sample 12 comprising entirely whole blood 20 . Whole blood 20 is in a mixed state. This indicates that the sample 12 in the sample tube 10 has not yet been separated, ie not centrifuged, for example.

[0082] Figure 1b A sample tube 10 is shown with a sample 12 comprising both gel 22 and whole blood 20 . Whole blood 20 is disposed on gel 22 . As already explained above, the gel 22 is already filled into the sample tube 10 by the manufacturer during the steps of manufacturing the sample t...

Abstract

The invention relates to a method for automatically recognising a state of a sample, in particular for recognising whether a sample has been centrifugated or not. The invention further relates to a device for analysing samples and to a laboratory automation system using the method according to the invention.

Description

technical field [0001] The present invention relates to a method for identifying the state of a sample, in particular a blood sample, in a sample tube extending in the longitudinal direction, from a predetermined set of states, wherein said set of states includes non-mixed state and mixed state. Background technique [0002] In order to undergo analysis, samples, in particular medical samples, and among them blood samples in particular, are often filled into conventional sample tubes. By way of example, the presence of disease or alcohol concentration in the blood can be determined within the scope of such an analysis. Typically, many analyzes require separation of individual components of such samples prior to analysis. During this process, usually multiple phases of different phase types are produced in the sample tube. [0003] By way of example, the following phases (more precisely, types of phases) are known in blood samples: [0004] - Air: the area not yet filled ...
