A delayed reaction to contact dermatitis from rubber latex is characterized by a response that occurs later than immediate reactions, typically manifesting within a period of hours to days following the exposure. In the case of latex allergy, delayed hypersensitivity reactions usually develop around 6 to 48 hours after contact with the allergen.

This time frame aligns with how the immune system responds to such allergens, where sensitization leads to an immune reaction that may not be evident until some time has elapsed after exposure.

In contrast, the other time frames provided do not fully encompass the common duration for a delayed reaction, as they either represent shorter intervals or do not match the typical onset indicative of delayed hypersensitivity in latex exposure scenarios.
