Abstract

The test kit includes a substrate and, welded or bonded thereto, a plastic sheet having blisters. One of the blisters is shaped as a siphon. The other blisters act as reaction vessels and also serve to receive and store a reagent. The test kit may contain a test strip in one of the blisters. The test kit is particularly suited for carrying out immunological tests, whereby the siphon markedly facilitates the procedure during the washing step.

Claims

1. A test kit for carrying out analytical tests, the test kit comprising a water-impermeable substrate and, bonded or welded thereto, a transparent plastic sheet including blisters arranged parallel to one another, wherein at least one blister includes an elongate container having an S-shaped part and a rinsing part connected to the elongate container by the S-shaped part, the elongate container and the rinsing part together functioning as a siphon.

2. The test kit according to claim 1, wherein at least one of the blisters contains a test strip.

3. The test kit according to claim 2, wherein the blister including the elongate container and the rinsing part includes, adjoining the container, a removal part having a cross-sectional area larger than a cross-sectional area of the container part.

4. The test kit according to claim 2, wherein the blisters not functioning as a siphon comprise an elongate reaction part and a funnel-shaped introduction part having a cross-sectional area larger than a cross-sectional area of the reaction part.

5. The test kit according to claim 4, wherein the removal part of the blister functioning as a siphon and the introduction part are side by side and can be cut through along a single straight line.

6. The test kit according to claim 5, including a preperforated line along the single straight line to facilitate cutting.

7. The test kit according to claim 1, including volumetric measurement scales beside or on each of the blisters not functioning as a siphon, in the region of the reaction part.

8. The test kit according to claim 2, wherein the test strip has a test area loaded with an immunological reactant for detection or quantification of total IgE, of an IgE specific for an inhaled allergen, or of an IgE specific for a food allergen.

9. The test kit according to claim 1, wherein the sheet is a plastic which is hydrophobic or has been made hydrophobic.

10. Use of the test kit according to claim 1, for carrying out an ELISA test.

11. The test kit according to claim 3, wherein the blisters not functioning as a siphon comprise an elongate reaction part and a funnel-shaped introduction part having a cross-sectional area larger than a cross-sectional area of the reaction part.

12. The test kit according to claim 11, wherein the removal part of the blister functioning as a siphon and the introduction part are side by side and can be cut through along a single straight line.

13. The test kit according to claim 12, further including a preperforated line along the single straight line to facilitate cutting.

14. The test kit according to claim 3, including volumetric measurement scales beside or on each of the blisters not functioning as a siphon, in the region of the reaction part.

15. The test kit according to claim 4, including volumetric measurement scales beside or on each of the blisters not function as a siphon, in the region of the reaction part.

16. The test kit according to claim 5, further including volumetric measurement scales beside or on each of the blisters not functioning as a siphon, in the region of the reaction part.

17. The test kit according to claim 3, wherein the test strip has a test area loaded with an immunological reactant for detection or quantification of total IgE, of an IgE specific for an inhaled allergen, or of an IgE specific for a food allergen.

18. The test kit according to claim 4, wherein the test strip has a test area loaded with an immunological reactant for detection or quantification of total IgE, of an IgE specific for an inhaled allergen, or of an IgE specific for a food allergen.

19. The test kit according to claim 3, wherein the sheet is a plastic which is hydrophobic or has been made hydrophobic.

20. The test kit according to claim 4, wherein the sheet is a plastic which is hydrophobic or has been made hydrophobic.
