Latex allergy is an allergic reaction to proteins found in natural rubber latex. Latex allergies are classified as either Type I, Type IV, or other types. Type I, or IgE-mediated, allergic reactions are the most common type of latex allergy. Type IV, or cell-mediated, allergic reactions are less common but more severe than Type I reactions.
Type I Allergy
Type I latex allergies are caused by an immune system overreaction to proteins found in natural rubber latex. Symptoms of a Type I latex allergy include hives, itching, swelling, and difficulty breathing. People with Type I latex allergies may experience anaphylaxis, a life-threatening allergic reaction that can cause a drop in blood pressure and difficulty breathing.
Type IV Allergy
Type IV latex allergies are caused by an immune system reaction to chemicals used in the manufacturing process of latex products. Symptoms of a Type IV latex allergy may include skin rashes, itching, redness, and swelling. These reactions generally occur hours or days after contact with the latex. People with Type IV latex allergies may also experience anaphylaxis.
Conclusion
No, latex allergy is not classified as Type 4. Latex allergies are classified as either Type I, Type IV, or other types. Type I, or IgE-mediated, allergic reactions are the most common type of latex allergy. Type IV, or cell-mediated, allergic reactions are less common but more severe than Type I reactions.
