Linked drugs / medications
2Medication information is educational only. A doctor or pharmacist should advise whether any medicine is appropriate.
Treatments, therapies and supportive options
1Grouped by treatment type. These are educational database links, not personal treatment recommendations. Evidence labels are shown only where stored in the EH database.
Linked diagnostic tests and investigations
13These are pulled from both EH diagnostic-test link tables, including the older large test-link table.

- Carbon Dioxide Total Content (TCO2)
- Cerebrospinal Fluid Protein Concentration
- Expiratory Reserve Volume (ERV)
- Fibrin Degradation Products (FDPs, Fibrin Split Products, FSPs, Fibrin Breakdown Products, Fbps)
- Inspiratory Capacity (IC)
- Maximum Voluntary Ventilation (MVV)
- Peak Expiratory Flow Rate (PEFR)
- Protein Electrophoresis (Blood, Serum Protein)

Biological and test markers
13This visual map uses existing EH database links to show biological agents and lab markers reported as increased, decreased, or associated with this condition. These are educational relationships only; test results must be interpreted by a qualified clinician because ranges vary by lab, method, age, sex and clinical context.
