How reliable is the vitamin d rapid self-test?

The kiweno vitamin d quick test can detect the vitamin D level with high reliability.

In cooperation with our parent company Immundignostik AG, a renowned company in the field of laboratory diagnostics, many resources were invested in the development of this innovative rapid test procedure. The new rapid test procedure was of course checked and tested to ensure that the quality of the results was the same as in a laboratory evaluation. A comparative study carried out by Immundiagnostik AG (download) shows that the values measured by the rapid test method are very comparable with the laboratory measurements (measurement with mass spectrometry, ELISA). The kiweno vitamin d rapid test uses the same rapid test procedure as the Preventis SmarTest vitamin D used in the study.

Nevertheless, incorrect results may be obtained in individual cases. If the results are questionable, further clinical tests should be carried out. As with all diagnostic tests, a final finding should not be based on a single result, but only after the clinical picture has been fully clarified by the attending physician.

The vitamin d rapid test has a measuring range of 5-100 ng/ml 25(OH)-Vitamin D.

The test detects 25(OH) vitamin D2, 25(OH) vitamin D3, 1,25(OH)2 vitamin D2 and 1,25(OH)2 vitamin D3. There is no cross-reactivity to 1,24(OH)2-vitamin D2, 1,24(OH)2-vitamin D3 or 3-epi-(OH)-vitamin D3. The kiweno vitamin d rapid test result is not affected by bilirubin, triglycerides, cholesterol, vitamin B12 or vitamin C. The coefficient of variation is 25.8% for repeated measurements with one rapid test batch and 3-37% for repeated measurements with different rapid test batches. A comparative measurement of 27 patient samples with the Schenlltest method and the reference method LC-MS/MS (liquid chromatography-mass spectrometry/mass spectrometry) showed a very good agreement between the two methods (87.5%).
