Abstract

A test for diagnostic tests. particularly for testing blood prior to a transfusion is disclosed. The test element comprises at least two test units for carrying out at least two tests. The test element is provided with a fixing means for fixing said test element.

Claims

1. A test element for diagnostic tests comprising

at least two test units for performing at least two tests, and

a fixing means for fixing the test element.

2. The test element according to claim 1 in which the fixing means is formed in such a way that the test elements may be fixed to a blood bottle.

3. The test element according to claim 1 or claim 2 in which the fixing means is a bonding foil.

4. The test element according to claim 1 or claim 2 in which the fixing means is a cable tie.

5. The test element according to claim 1 or claim 2 in which in at least one of the at least two test units, the test result is maintained at least 45 days.

6. The test element according to claim 1 or claim 2 in which at least one of the at least two test elements is formed in such a way that, after the performance of the tests, no fluid emerges.

7. The test element according to claim 1 or claim 2 in which by means of one of the at least two test elements bottle blood for blood transfusions is tested.

8. The test element according to claim 7 in which the test unit for bottle blood comprises at least three test chambers or test fields.

9. The test element according to claim 8 in which three of the at least three test chambers or test fields respectively comprise anti-A, anti-B, and anti-D reagents.

10. The test element according to claim 1 or claim 2 in which by means of the test unit, the blood of a receptor of a blood transfusion is tested.

11. The test element according to claim 10 in which the test unit for the blood of a receptor comprises at least two test chambers or test fields.

12. The test element according to claim 11 in which two of the at least two test chambers or test fields respectively contain anti-A and anti-B reagents.

13. A method for testing blood during the preparation and performance of blood transfusions, wherein the method comprises the following steps:

testings bottle blood by means of the first test unit of the test element according to claim 1 or claim 2;

fixing the test element on a blood bottle containing the bottle blood by means of the fixing means; and

testing the blood of the receptor by means of the second test unit of the test element.

14. The method according claim 13 additionally comprising, after the testing of the bottle blood and obtaining a first test result and after the testing of the receptor blood and obtaining a second test result, the step of comprising the test results.
