Angio-oedema and anaphylaxis - Making a diagnosis
How do I know my patient has it?
- A detailed history and examination will help diagnose angio-oedema and anaphylaxis.
- Investigations are rarely needed in primary care as a referral is required. Nevertheless, blood tests may be appropriate to help identify the underlying cause. Tests include:
- Thyroid function test (TFTs) and liver function tests (LFTs).
- C-reactive protein (CRP) and an erythrocyte sedimentation rate (ESR) to exclude chronic inflammation or infection.
