The serum Clonazepam Level test is crucial for assessing benzodiazepine (Clonazepam) overdose and toxicity concerns. Clinical signs may include respiratory depression, hypoxemia, apnea, hypotension, bradycardia, cardiac arrest, pulmonary aspiration, and coma. Healthcare professionals rely on this test to differentiate overdose origins, detect substances and metabolites, and investigate road accidents, drug overdoses, and poisoning incidents, whether accidental or intentional.
