Biochip Array Technology explained The 'Gold Standard' in multiplex testing

Biochip Background Established in 1982, Randox is a market leader in the field of high quality diagnostic solutions. With origins in clinical chemistry, Randox adapted its expertise and product range to include immunoassays, quality management and life science solutions. Randox’s vision is to develop innovative and clinically meaningful diagnostics, ultimately improving laboratory testing and healthcare solutions worldwide. Approximately 2% of all healthcare costs are diagnostics; however, 70-80% of all clinical decisions are based on the results of diagnostic tests. Traditionally six or seven...

Put simply, Biochip Array Technology is a multi-analyte testing platform allowing the simultaneous quantitative or qualitative detection of a wide range of analytes from a single sample. It provides a unique platform for assessment of biological samples in a rapid, accurate and easy to use format. The problem with traditional diagnosis Traditional diagnosis takes the form of single analyte assays, even though several tests are usually required. This may result in multiple patient blood draws, increased reagent volume, ultimately increasing time to diagnosis. The solution In response, Randox created...

ASSAY FORMATS Protein / Antibody assay formats Competitive immunoassay In a competitive immunoassay, the more analyte present in a sample, the less labelled conjugate that will bind to the immunoreaction site. Therefore the signal produced will be low. If there is little analyte in the sample, more labelled conjugate will bind to the capture antibody resulting in a higher signal. Sandwich immunoassay In a sandwich immunoassay, the more analyte present in a sample, the more conjugate will bind to the capture antibody. As a result, the signal will be high. Conversely, lower signal is produced when...

The biochip detection system is based on a chemiluminescent signal. This is the emission of light, without heat, as a result of a chemical reaction. An enzyme is used to catalyse the chemical reaction on the biochip which generates the chemiluminescent signal. The light emitted from the chemiluminescent reaction that takes place in each DTR is simultaneously detected and quantified using a Charge - Coupled Device (CCD) Camera. This CCD Camera simultaneously records the light emission from all the discrete test sites on each biochip on the biochip carrier. Analysis process on biochip systems 2....

Key Features and Benefits Highly accurate testing • BAT has a proven high standard of accurate test results with CV’s <10% • Multiplex analysis minimises analytical variation between tests Better patient diagnosis • Testing for multiple markers simultaneously increases the amount of patient information rapidly available to the clinician, allowing for more informed patient diagnosis Optimum efficiency • M ulti-analyte reagents and quality control material, provides highly efficient testing while eliminating any wastage Small sample volume • Reduced sample volume requirements puts the patient at...
