Impact of Allergic Response
IMMEDIATE TYPE I RESPONSE: NATURAL RUBBER LATEX ALLERGY
A latex Type I response is a reaction to residual proteins found in natural rubber latex.4 The reaction is immediate, typically occurring 5–30 minutes after initial contact. The symptoms are commonly:
- Swelling and redness, local to the site of exposure
- Non-specific symptoms such as itching and burning
The symptoms can spread to areas remote to the site of contact with the glove, and can be accompanied by:
- Bronchial obstruction
In rare cases, symptoms of anaphylaxis can occur.

DELAYED TYPE IV RESPONSE: DELAYED OR ALLERGIC CONTACT DERMATITIS
A chemical Type IV allergy is a reaction to specific allergens such as chemical residues from the glove manufacturing process (commonly known as chemical accelerators). The response is delayed rather than immediate, usually occurring 6- 48 hours after initial contact, although symptoms can last for up to 4 days.
The symptoms include:
- Dryness of the skin at the site (dermatitis may extend beyond the
area of contact)
Delayed or allergic contact dermatitis possibly has an itchy rash comprising scaling, redness and blisters
