Overview
Laboratory findings is usually normal among patients with epistaxis, but when bleeding is heavy or physician is suspicious to coagulopathy, The following tests should be performed: CBC, PT, PTT, BT.
Laboratory Findings
Laboratory findings is usually normal among patients with epistaxis, but when bleeding is heavy or physician is suspicious to coagulopathy, The following studies should be considered:.[1] [2] [3]
- Complete blood count (CBC): Reduced hemoglobin level is important to find the cause and management patients with heavy and recurrent epistaxis.
- Platelet count: Reduced platelet count is important to find the cause and management patients with heavy and recurrent epistaxis.
- Prothrombin time (PT): Increased PT is important to find the cause and management patients with heavy and recurrent epistaxis.
- Partial thromboplastin time (PTT): Increases PTT is important to find the cause and management patients with heavy and recurrent epistaxis.
- Bleeding time (BT): Increased BT is important to find the cause and management patients with heavy and recurrent epistaxis.
