Radioallergosorbent testing with p‐tolyl monoisocyanate in toluene diisocyanate workers

Abstract
Summary: Sera from 149 occupationally exposed toluene diisocyanate (TDI) workers were tested by RAST with p‐tolyl monoisocyanate human serum albumin (TMI‐HSA). Of the seven positives, one had a history suggestive of TDI asthma and one had a rash which may have been TDI related. These results indicate that false positive RAST with TMI‐HSA may occur in asymptomatic workers.
