Tests
Blood tests can show signs of inflammation and infection:
- FBC (full blood count) – raised white cells indicate infection
- CRP (C-reactive protein) – indicates inflammation
- ESR (erythrocyte sedimentation rate) – indicates inflammation
Blood tests can also demonstrate any damage to the liver or pancreas as a result of blockage or infection:
- Liver function tests – One of these tests called alkaline phosphatase is very high in infection of the bile ducts. Another test is bilirubin which will be raised if the bile ducts are blocked
- Amylase – Raised if pancreas is damaged.
Ultrasound will show almost all gallstones over 4mm. CT and MRI scans may also be used.
