## Indications for use
For the quantitative determination of acetaminophen in serum. For IN VITRO diagnostic use. Acetaminophen (paracetamol) is used as an analgesic in many different formulations (1). While therapeutic doses rarely cause adverse side effects, the effect of long term treatment with acetaminophen is unclear. Cases have been reported where chronic excessive use of acetaminophen has led to hepatotoxicity and nephrotoxicity (2,3). In cases of acute overdosage, acetaminophen can cause severe hepatic damage leading to hepatic failure if untreated (4,5,6). The management of acetaminophen overdose requires early recognition of the drug in the bloodstream. Toxicity is generally reported at concentrations over 20 mg/dL.. N-acetylcysteine has been used as an antidote in conjunction with intensive support care. Early diagnosis of acetaminophen-induced hepatotoxicity is important since initiation of therapy within 8 hours of ingestion lessens the potential for hepatic injury, and decreases the mortality rate (7). The majority of methods for measuring acetaminophen are based on spectrophotometric or chromatographic principles. Chromatographic methods are specific for the parent compound, however, they are not well suited to emergency laboratories. Spectrophotometric methods are simpler and more rapid, but do not always offer the desired specificity. This spectrophotometric method is rapid, reliable, convenient, and specific for acetaminophen.
