Abstract
There is a lack of published data on the role of patch testing in patients with so‐called multiple chemical sensitivity (MCS), also known as idiopathic environmental intolerances (IEI).(1) This disputed chronic condition is characterised by symptoms that the affected person attributes to low‐level exposures to commonly used chemicals.(2) Symptoms are typically vague and non‐specific and may include fatigue, headaches, nausea, dizziness, a sensation of skin burning or pain.
