Acetaminophen is known as paracetamol in many countries outside the US. It is one of the most frequently used oral analgesics and antipyretics. It has an outstanding safety profile when administered in an appropriate dose, but hepatotoxicity can occur after overdose or when misused in at-risk populations. GENEMEDI developed the antigens and antibodies for the diagnosis of potential acetaminophen toxicity based on ELISA, Lateral flow immunoassay (LFIA), colloidal gold immunochromatographic assay, Chemiluminescent immunoassay (CLIA), turbidimetric inhibition immuno assay (TINIA), immunonephelometry and POCT.
