Accurate, fast, reliable

Randox Toxicology provides highly sensitive ELISA kits for the rapid detection of drugs and metabolites in various biological specimens. An Enzyme-Linked Immunosorbent Assay, or ELISA, is a test which uses antibodies to detect the presence of a substance. A 96-well microtitre plate is supplied precoated with an antibody. If the drug being tested is present in the sample, it will compete with the horseradish peroxidase enzyme labelled antigen for a limited number of antibody sites on the microtitre plate. Results are produced based on an enzymatic colour change.

Randox Toxicology has an ever expanding test menu which includes a range of New Psychoactive Substances, drugs of abuse, stimulants, analgesics and sedatives. Significant re-investment in Research and Development allows Randox Toxicology to develop assays with relevant values and optimise them for best performance in a variety of matrices. Offering excellent cross-reactivity and unrivalled limits of detection, Randox Toxicology develops the highest quality ELISAs available on the market, with results providing excellent correlation with confirmatory methods.
