Question: 1 / 660

What is primarily responsible for Type 1 latex hypersensitivity?

Rubber proteins

Type 1 latex hypersensitivity is primarily caused by exposure to proteins found in natural rubber latex. These proteins can trigger an immediate allergic reaction in sensitized individuals upon contact, leading to symptoms such as hives, sneezing, itching, or more severe responses like anaphylaxis.

Natural rubber latex contains a complex mixture of these proteins, which are the actual allergens that the immune system reacts to in those individuals who have developed this allergy. In the context of the choices provided, while items like latex gloves and medical equipment can be sources of exposure, it is the rubber proteins within the latex itself that are the main culprits behind the hypersensitivity reaction.

This understanding underscores the importance of recognizing and avoiding materials that contain these proteins in clinical settings to prevent allergic reactions in susceptible individuals.
