Randox Biochip Array Technology Thailand — Multi-Analyte Simultaneous Food Safety Screening | BCST
Biochip Array Technology in Thailand — Testing Multiple Parameters at Once
Biochip Array Technology in Thailand, available exclusively through BCST via Randox Food Diagnostics, represents the most significant advance in food safety screening technology available to the Thai market. BAT is a multi-analyte simultaneous screening platform. Specifically, single sample analyzed once on a Randox Biochip Array instrument, produces results for multiple residues and contaminants simultaneously — in a single analytical run, from a single sample preparation.
This is not incremental improvement over conventional ELISA. It is a fundamentally different approach to the economics and logistics of food safety testing. Furthermore, for any operation that currently runs multiple individual ELISA assays to screen for multiple analyte classes, BAT changes the calculation entirely — Consequently, reducing reagent cost per analyte, reducing laboratory labor, reducing total run time, and producing a single consolidated results output covering multiple parameters simultaneously.
How Biochip Array Technology Works
The Biochip — A 9×9mm Ceramic Platform
A Biochip is a small solid-phase device — 9mm × 9mm in dimension — containing multiple discrete test regions (DTRs) arranged in an array on a ceramic surface. Each discrete test region is sensitized with a different capture reagent specific to a different analyte or analyte class. When a prepared sample contacts the Biochip, simultaneous competitive immunoassay reactions occur across all discrete test regions at once. This replaces what would otherwise require multiple sequential individual assays.
Chemiluminescent Detection
The Randox Evidence Investigator and Evidence MultiSTAT use a chemiluminescent detection system. After the immunoassay reactions complete, the instrument illuminates each discrete test region and measures the light emission from each point simultaneously using unique image processing software. The instrument automatically translates the Relative Light Units (RLU) from chemiluminescent reactions into qualitative or semi-quantitative results. Consequently, no manual calculation or external software manipulation of results is required — reducing scope for operator error entirely.
Semi-Quantitative Results and Their Value
BAT results are semi-quantitative for most arrays — providing concentration information rather than simple positive/negative outputs. This matters for two distinct reasons. First, it enables risk assessment relative to regulatory thresholds — a result significantly below the MRL carries different management significance from a result just below threshold. Second, it makes the screening result more informative for directing confirmatory resources — a result well below threshold does not require the same confirmatory attention as a borderline result.
AOAC Certification — Myco 7 Biochip Array
In November 2025, the Randox Myco 7 Biochip Array received AOAC International certification — the globally recognized independent standard for analytical method validation in food safety, environmental, and agricultural testing. AOAC certification confirms that a method meets defined performance criteria for accuracy, precision, and selectivity, verified by independent testing against reference methods.
For Thai food producers, exporters, and laboratories using Randox Biochip Array Technology through BCST, AOAC certification provides the highest available level of independent assurance that the method performs as claimed. This is particularly significant for operations supplying buyers or markets that require AOAC-validated methods as part of their supplier qualification or export documentation requirements.
BAT vs ELISA — When to Use Which
Biochip Array Technology and ELISA are complementary technologies within the Randox portfolio — not competing ones. Each serves a different operational context.
ELISA is appropriate for laboratories beginning systematic food safety screening, for operations testing moderate volumes for a limited number of analytes, and for any operation where instrument capital investment is not yet justified by testing volume. Additionally, ELISA requires only standard laboratory equipment — a microplate reader, incubator, and pipettes.
Biochip Array Technology is appropriate for three operational contexts. First, high-volume operations screening for multiple analyte classes simultaneously benefit most. Second, operations where consolidated multi-analyte testing savings exceed the instrument investment over time gain significant economic advantage. Third, operations requiring LC-MS/MS comparable results for regulatory documentation need this platform.
Therefore BCST advises on the correct technology for each client’s specific operation. This assessment covers testing volume, analyte requirements, and regulatory obligations. Contact BCST before making any instrument investment decision.
