[Diagnosis of multiple chemical sensitivity by chemical compounds exposure tests].

Objective: There are no specific signs or symptoms in Multiple Chemical Sensitivity (MCS), so diagnosis of MCS depends on a history, QEESI symptom scores and exclusion of other diseases. A gold standard of diagnosis of MCS is a chemical compound exposure test in which changes of symptoms are used to decide the results positive or negative. We have done chemical compound exposure tests to diagnose MCS in 51 patients.

[Clinical aspects of patients with MCS - from the standpoint of allergy].

Background: "Sick House Syndrome" is thought to be an illness caused by indoor environments such as allergens, bacteria and chemical compounds. But it is not yet an established clinical entity. "Sick House Syndrome" overlaps in part with Multiple Chemical Sensitivity (MCS) whose symptoms are induced by very small amount of volatile chemical compounds.
