Definitions
- the invention relates to a system for storing and transporting sample material absorbent material.
- Glycation of hemoglobin and serum proteins is increased in patients with diabetes mellitus. The increase depends on the glucose concentration and the incubation time of the protein with glucose. In these cases, the glycation of serum proteins, including hemoglobin, is not carried out enzymatically, but uncatalyzed by chemical reaction of the glucose with amino groups of the proteins.
- the expert assumes that the concentration of a certain protein-glucose adduct reflects both the glucose concentration over a certain time and the conversion rate of the protein.
- Glycated hemoglobin is considered an indicator of the mean blood glucose concentration during the last two to three months before blood collection and examination.
- Glycated serum protein reflects the blood glucose concentration over a shorter period of time. The determination of glycated protein such as glycated hemoglobin (HbA 1c ) or glycated serum protein is therefore of great importance for the long-term glycemic control of diabetes patients.
- the object of the present invention was therefore to overcome the disadvantages of the prior art Eliminate technology.
- the level of glycated protein in a sample should contribute Storage can be stabilized on an absorbent material.
- Glycated after storage Proteins on an absorbent material should find a value for the glycated protein as it existed after sampling and before storage.
- the handling the carrier containing sample material can be simplified and made safer.
- the invention relates to a system for storing and transporting sample material.
- the system consists of an absorbent material for absorbing liquid samples, a closable one Container in which the material can be stored and transported, and one moisture absorbing medium.
- test reagents are included.
- the absorbent material which the Absorption of the sample material is used no test reagents.
- test reagents are those reagents or substances that usually in analytical test elements, such as colorimetric test strips or electrochemical sensors and biosensors are included and the detection of one Serve target analytes.
- test reagents are substances that work with the target analyte enter into an interaction, the detection of which directly or indirectly, the means, if necessary, only after adding additional reagents.
- Test reagents should not include reagents or substances that are not directly detectable serve as a target analyte. Such substances are not allowed with the target analyte in the sample Enter into an interaction that allows its detection. Examples include stabilizers, which also includes enzyme substrates and coenzymes, which are mainly used for Stabilization of the analyte serve, buffer substances, spreading agents and other usual, the Substances familiar to experts.
- the system according to the invention is for transporting and storing items to be analyzed Sample material, in particular liquid samples, especially body fluids such as blood, Plasma, serum, urine, saliva etc. are suitable.
- Sample material in particular liquid samples, especially body fluids such as blood, Plasma, serum, urine, saliva etc. are suitable.

- two layers of absorbent material are arranged next to one another in a touching manner on an inert carrier material such that a liquid transfer from the first to the second layer is possible when the first layer is filled with liquid.
- the absorbency of the matrix material of the first layer should be the same as or greater than that of the second adjacent layer. This avoids the formation of disturbing suction effects when sample material is applied to the first layer.
- the layers of the absorbent material must be attached to the inert carrier in such a way that the first layer can be completely separated from the second layer after application and drying of liquid sample material. This is particularly possible if the first layer is only attached relatively loosely or only at certain points.
- the two layers of the absorbent material so touching each other on the backing material be arranged so that a liquid transfer from the first layer into the second Layer is possible if the first layer is filled with liquid. This is then possible if there is at least edge contact between the two layers. But is even better a slight overlap of the two layers is provided.
- Those are particularly preferred Layers are then arranged so that the second layer slightly overlaps the first layer.
- the size of the Layers of the absorbent material are chosen so that the first layer, which later also is used as an evaluation layer with which the sample liquid can be filled completely. Excess sample liquid is then taken up by the second layer. Which Amounts of sample sufficient to determine a particular analyte depends on the type of the analyte to be determined. As a rule, however, 5-20 ⁇ l, usually 10 ⁇ l sample are sufficient out. This volume must be taken up by the first matrix layer and later again can be eluted. For safety, the second matrix layer, which functions as a Absorbent layer, can take up a larger volume.
- Suction volume of 10-50 ⁇ l, preferably 10-30 ⁇ l, particularly preferably 20 ⁇ l are usually sufficient for this.
- the usual dimensions of the layers of absorbent material should be like this be such that the suction volume of the two layers taken together is at least 30 ⁇ l, better at least 50 ⁇ l.
- Such a dimensioning ensures that with both small and large drops of liquid on the first matrix layer different elements of the invention the same amount of sample is applied.
- the smaller first layer usually has one to achieve a sufficient suction volume Area from 3x3 to 8x8 mm.
- a homogeneous distribution of liquid sample material is achieved in the first layer. Because the first layer is completely filled with liquid sample material concentration gradients of the analyte cannot form within this layer, otherwise always to be observed in the peripheral zones of the elements of the prior art were. Concentration-related measurement differences when determining analytes are avoided.

It is slightly overlapped by the second layer of the absorbent material 2, which absorbs excess liquid of the sample material when the first layer 1 is filled.
- At the end of the carrier material 3 below the first layer 1 there is a recess 5 in the carrier material 3. This recess 5 enables or makes it easier to grip the first layer 1, for example with a pair of tweezers, in order to Remove from the element for purposes of elution and subsequent analysis steps.
- the two layers are absorbent Material 1, 2 attached to the inert support material 3 so that two opposite Ends of the carrier material 3 are free and can be gripped with the fingers.
- the two layers of the absorbent material 1, 2 are on the carrier material by means of double-sided adhesive tape 4, 6 3 attached.
- the carrier material 3 has a predetermined breaking point 7, which is arranged that when bending, breaking or tearing, the element can be divided into two parts there, that the one the first layer of absorbent material 1 and the other the second layer absorbent material 2 carries.
- the Breakage 7 should be a notch.
