Investigation in bruising
Appropriate baseline laboratory investigations include:
- full blood count (FBC) with differential
- peripheral blood smear for platelet abnormalities
- coagulation screen
- prothrombin time (PT) - to assess the extrinsic and common clotting pathways
- activated partial thromboplastin time (aPTT) - to assess the intrinsic pathway
- Clauss fibrinogen - for fibrinogen function
- thrombin time - for fibrinogen functional defects (1)
- hepatic and renal functions (2)
