Myths vs facts: STI Test and Allergie

Myths vs. facts: STI test and allergy test. STI tests (sexually transmitted infections) are medically validated when based on PCR or blood analysis. A common myth is that a negative test provides immediate safety – in reality, window periods exist during which infections are not yet detectable. Home tests vary in accuracy; only certified laboratories yield reliable results. For allergy tests, the distinction is crucial: IgE-based tests (e.g., skin prick) are clinically accepted, while IgG tests for food intolerances lack scientific evidence and can lead to unnecessary dietary restrictions. The MyBody-X website itself warns against such tests. Overall, STI tests are reliable when used correctly, but education about limitations is needed. Allergy tests should only be performed on medical indication. The evidence is mixed: strong clinical data for STI tests, but lack of validation for IgG allergy tests. Caution is warranted, especially with direct-to-consumer marketing.
