Biochip Array Technology

Our Multiplexing Technology

Biochip Array Technology offers simultaneous detection of multiple drug classes from a single specimen.

Moving away from traditional single analyte assays, Biochip Array Technology boasts cutting-edge multiplex testing capabilities providing rapid and accurate drug detection from a single sample. Based on ELISA principles, the biochip is a solid state device with discrete test sites onto which antibodies specific to different drug compounds are immobilised and stabilised. Competitive chemiluminescent immunoassays are then employed, offering a highly sensitive screen.

Designed to work across a wide variety of matrices, this revolutionary multi-analyte testing platform allows toxicologists to achieve a complete immunoassay profile in the initial screening phase. Offering the most advanced screening technology on the market, Randox Toxicology has transformed the landscape of drugs of abuse testing. Our six drugs of abuse biochip arrays form part of our unrivalled toxicology test menu capable of detecting over 500 drugs.

Features & Benefits

No. 1 Supplier of NPS Tests

New Psychoactive Substances including four Synthetic Cannabinoids (SPICE), three Synthetic Cathinones (Bath Salts), NBOMe and DOx Series.

Simultaneous Analyte Detection

The multiplex testing capabilities of Biochip Array Technology facilitates simultaneous screening of various drug metabolites from a single sample.

Accurate Testing

Multiplex analysis minimises analytical variation between tests and has a proven high standard of accurate tests results with CVs typically <10%.

Small Sample Volume

Biochip Array Technology requires a small volume of sample to produce a complete sample profile, leaving more sample remaining for confirmatory testing.

Extensive Test Menu

Six drugs of abuse biochip arrays are available and form part of the world's largest toxicology test menu which can facilitate screening of over 500 drugs of abuse.

Optimum Efficiency

Multi-analyte controls and calibrators and multiplex testing capabilities facilitate laboratory efficiency and deliver a cost consolidating solution for the toxicology laboratory.
