How reliable are the tests?

Andreas Bobrowski, chairman of the Professional Association of German Laboratory Physicians, is critical of the accuracy of these blood tests. “In terms of quality, home tests are significantly inferior to laboratory tests because the test execution is naturally fraught with certain problems and pre-analytical errors can occur. There is also no quality control,” he explains. There are three problems with home blood tests. Firstly, errors can occur in the indication presentation. This means that patients choose the wrong test. Secondly, the most common source of error is pre-analytics, i.e. the preparation for the test and the blood draw. 75 percent of all errors occur here, says Bobrowski.
