acceleration sensitive indicator

Abstract

Disclosed is an acceleration-sensitive indicator for indicating the centrifugation state of a biological sample; a sample container including the acceleration-sensitive indicator; a centrifuge for centrifuging the sample container; and an analysis system for analyzing centrifuged sample. The indicator includes at least one closed chamber formed between two opposing surfaces. The chamber comprises at least one indication zone comprising at least two fluid transfer zones or at least one particle transfer zone. The at least one fluid transfer zone comprises at least one solid support phase and at least one fluid stabilized in the solid support phase, or at least one non-stabilized non-Newtonian fluid having thixotropic and / or shear thinning properties. The at least one particle transfer zone includes at least one particle stabilization fluid comprising stabilized dispersed particles.

Description

technical field

[0001] The present invention relates to an acceleration sensitive indicator for indicating the application of an acceleration field; a sample container comprising the indicator for centrifuging a biological sample contained therein; and an analysis system for determining The centrifugation state of the sample. Background technique

[0002] Proper analysis of biological samples may depend on the centrifugation state of the biological sample, so it is often important to determine whether the centrifugation step to separate the various sample components has been completed. Not only the lack of a complete centrifugation step may affect the validity of the analytical test, but additional unnecessary centrifugation steps applied to a sample may negatively affect the quality of the analysis performed on that sample. For example, many sample tubes used to prepare plasma or serum from whole blood samples include a gel to stably hold the sediment (which may contain pe...
