What Tryptase measures
Tryptase gives context about mast-cell-related activation rather than histamine clearance alone. That makes it helpful when production, reactivity, and clearance may all be mixing together.
Why this marker matters
When HDC or histamine-production pathways look relevant, tryptase helps show whether the broader reactivity context deserves attention.
When to check it
- when histamine symptoms feel more production- or activation-driven
- when HDC and histamine pathways look relevant
- when symptom patterns are stronger than clearance-only explanations
How to interpret it
- use it with symptom patterns and trigger context
- interpret it alongside DAO activity or plasma histamine where relevant
- avoid treating it as a standalone diagnosis
Where it fits in DNA follow-up
Tryptase helps separate production and activation context from clearance-only histamine questions.
Example interpretation
Your histamine pattern may deserve a broader reactivity review because tryptase can show whether activation context belongs in the picture.
