BACKGROUND:
We have previously noted that one natural rubber latex (NRL) glove brand used for skin prick testing in the diagnosis of NRL allergy contained cow's milk casein.

OBJECTIVE:

The casein content of 30 NRL glove extracts (1:5 wt/vol) was measured by ....

RESULTS:
The casein content of the glove used in NRL allergy screening (Triflex, Baxter) was rather high (ie, about 400 microgram/g of glove). .... detected distinct amounts of casein in 8, minimal amounts in 7, and no casein in the remaining 15 NRL glove brands.
