Turbidimetry and Nephelometry Instrumentation

When a specific antisera and sample containing antigen are mixed in solution with reaction buffer they form a precipitate. The solution becomes cloudy. Turbidimetry measures the amount of light that can pass through this solution, which will decrease as the amount of precipitate increases. Nephelometry is similar but the analyser measures the amount of light scattered by the precipitate. Both turbidimetry and nephelometry are performed using automated laboratory analysers such as Optilite^® and SPA_PLUS^® analysers

• Hands on time is minimised by the automatic dilutions performed by the SPA_PLUS and Optilite analysers
• Results are generated rapidly as the reaction takes place in the analyser cuvette
• Quality Control and patient sample results are read directly off a calibration curve plotted automatically by the analyser
• Low level result reporting can be achieved using our range of latex-enhanced assays
• A wide range of assays are available for the SPA_PLUS and Optilite turbidimetric analyzers
