wie lange vor allergietest cetirizin absetzen — can a microbiome test help?

The question of how long to stop cetirizine before an allergy test is not directly answered in the provided MyBody-X articles. General medical guidelines recommend a washout period of 3–7 days depending on the test type (prick test, intradermal test), because cetirizine suppresses the histamine response. A microbiome test (such as the one offered by MyBody-X) cannot diagnose allergies or replace the need to discontinue antihistamines. It may provide insights into gut flora that are indirectly linked to immune function and allergic predisposition, but the evidence for a direct clinical recommendation is weak („mixed/unclear“). For the exact withdrawal period before an allergy test, consult your physician or the test's official instructions.
