Which Growth Drivers Are Expected To Support The Specific Immunoglobulin G Subclass 4 (IgG4) Testing Market Forward?
The increasing prevalence of allergic conditions is anticipated to drive expansion in the specific immunoglobulin G subclass 4 (IgG4) testing market. Allergic diseases are immune-system-triggered hypersensitivity issues, encompassing conditions such as food allergies, atopic dermatitis, asthma, and allergic rhinitis, which manifest when the immune system reacts abnormally to typically harmless substances. The rise in allergic disease prevalence is attributed to shifts in dietary patterns, as increased consumption of highly processed foods can alter gut microbiota and elevate the likelihood of developing allergic sensitization. Specific IgG4 testing facilitates the assessment of immune responses linked to repeated allergen exposure, thereby supporting clinicians in understanding tolerance patterns and interpreting complex allergy-related immune activity. For instance, in May 2024, according to the Food Standards Agency (FSA), a UK-based government body responsible for food safety and public health protection, approximately 6%, or 2.4 million, of the UK adult population was found to have a clinically confirmed food allergy. Therefore, the growing occurrence of allergic diseases is a key factor propelling the specific immunoglobulin G subclass 4 (IgG4) testing market forward.
