1.1 This test method covers an immunological method to determnine the amount of antigenic protcin in natural rubber and its products using rabbit antisera specifc for natural rubber latex NRL) proteins. This immunoassay procedure quantita-ively mcasures the level of antigenic latex proteins in solution using an inhibition format. The samples may include glove or other rubber product extracts which huve been collected in order to measure the latex protein levels. Alhough this method detects antigenic protcins, it should not be considered a a measure of allergenic proteins. Correlation of protein/antigen levels with the level of allergenic proteins has not been fully established.
