Surgical rubber gloves contain allergens derived from natural rubber latex which may sensitize, causing contact urticaria and even systemic reactions. We examined 15 hospital employees allergic in latex surgical gloves, using various skin tests and RAST, to determine the most reliable diagnostic method and to investigate coexistent allergy to glove powder and rubber chemicals. Prick testing using a stock solution made from one brand of latex glove yielded positive (2+ to 4+) reactions in all 15 employees; 8 retained positive reactions at a 1/10 dilution, 1 at 1/100 and 4 at 1/1000. A prick test using rubber‐tree sap ( Hevea brasiliensis ) was positive in 12/15 employees and a scratch‐chamber test using crushed rubber‐tree leaf was positive in 13/l5. A latex glove use test was positive in 12/13 employees and a latex RAST detected measurable amounts of specific IgE in 8/15. No positive prick lest reactions were obtained using glove powder. On patch testing, 2/15 employees showed delayed allergy to rubber chemicals but no immediate reactions were detected, The present results indicate that in addition to the use test, prick testing with a stock solution prepared from latex surgical gloves is an adequate test method for routine practice when diagnosing latex glove contact urticaria The correlation between prick tests and whole glove me tests was good, but latex RASTs yielded some negative results.
