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.


Other Tests

If available, spirometry can be used to augment monitoring of the patient's respiratory status.  A disposable peak flow meter might be a useful adjunct in this regard.
