What to watch with IgE Allergietest and Schlaf?

An IgE allergy test (e.g., MyBody-X) measures specific IgE antibodies against foods or inhalants. Evidence indicates that home tests have high false-positive rates – they are screening tools, not diagnostic. A positive IgE alone does not prove clinical allergy. Regarding sleep: allergic reactions (e.g., nasal congestion, itching) can impair sleep quality, but the test itself does not assess sleep. Circadian rhythms and sleep deprivation may influence IgE production and inflammatory markers, but the evidence is mostly mechanistic and insufficient for firm recommendations. If you have sleep issues, prioritize evaluating other causes (stress, sleep hygiene, respiratory conditions) first. The test may provide only supplementary clues. Beware of overinterpretation: a negative IgE test does not rule out allergies, and a positive result requires clinical confirmation. Evidence: practice.
