Laboratory Studies
- No laboratory studies are of diagnostic benefit. Baseline laboratory studies (eg, complete blood count [CBC], electrolyte tests, renal function studies) may be obtained in severe bite cases or if the patient has significant underlying medical problems. Coagulation studies are not indicated.
- An arterial blood gas (ABG) determination may be helpful if the patient's respiratory status is of concern.
Imaging Studies
- A chest radiograph is beneficial in patients who have severe envenomation, who require intubation, or who show evidence of cardiopulmonary failure.
