Anaphylactic reactions to latex have occurred in people who have previously experienced only mild hand rashes from latex. FDA-approved lab tests to measure latex allergy are available. These tests are limited because a positive result does not always prove or disprove latex allergy. Tests include the Pharmacia CAP and the AlaSTAT tests. A negative lab test despite a strong positive history of allergic sensitivity would need a skin prick test to confirm the diagnosis.
People heavily exposed to latex are much more likely to become allergic.
