Diagnostic workflow

From history to molecules: a practical diagnostic workflow

Molecular allergology is most useful when it is placed inside a stepwise diagnostic pathway: history, examination, extract-based sensitisation testing where appropriate, molecular testing when it adds resolution, interpretation, and challenge testing when uncertainty remains.

Primer

What component-resolved diagnostics adds to allergy care

Traditional extract-based testing can identify sensitisation, but it may not explain which proteins are driving a result. Component-resolved diagnostics helps clinicians look beneath the extract and consider whether a pattern suggests genuine primary sensitisation, cross-reactivity, or a lower-risk profile. For MAA, this is one of the central educational opportunities: helping clinicians move from a positive result to a more nuanced clinical interpretation.

Clinical interpretation

Cross-reactivity is not always clinical allergy

Molecular allergology can help separate broad sensitisation from clinically meaningful allergy. Panallergens and homologous proteins may produce positive tests across multiple sources, but the clinical risk can vary greatly. A structured molecular approach can support better conversations around avoidance, challenge decisions, risk stratification, and referral.

Allergen families

Allergen families: the grammar of molecular allergology

Component names become clinically useful when they are grouped into allergen families such as PR-10 proteins, profilins, lipid transfer proteins, storage proteins, tropomyosins, lipocalins, serum albumins, and CCD-bearing glycoproteins.

Interpretation pitfall

Cross-reactive carbohydrate determinants and false clarity

CCD sensitisation can contribute to broad in vitro IgE reactivity that does not necessarily match symptoms. Recognising CCD patterns helps avoid over-calling clinically irrelevant sensitisation.

Immunotherapy

Molecular profiles and immunotherapy conversations

Molecular profiles may help clarify whether a patient is primarily sensitised to major allergen components represented in an immunotherapy product, or whether the test pattern is dominated by cross-reactive components. MAA resources will focus on the practical interpretation questions that arise before and during immunotherapy discussions.

Source to component

From allergen source to molecular pattern

Pollen, mite, food, venom, latex, and animal dander each contain different mixtures of major, minor, stable, labile, genuine, and cross-reactive molecules. Interpretation starts with the source but cannot stop there.

Education design

Why molecular allergology education should be case-based

Molecular results become most useful when they are interpreted alongside history, exposure, symptoms, geography, and treatment goals. Case-based education keeps the focus on clinical reasoning rather than isolated markers. This is why MAA plans to develop practical case discussions as a core resource format.
