Immunoturbidimetry is a powerful analytical technique that combines the principles of turbidimetry and nephelometry to quantitatively determine the concentration of proteins in a sample of interest. Both methods rely on the measurement of light scattering, but employ different techniques to achieve this end. Turbidimetry measures the absorbance of light caused by the presence of particles in the sample, such as protein molecules. Nephelometry, on the other hand, measures the scattered light at a fixed angle, which is inversely proportional to the protein concentration in the sample. In the past, nephelometric assays were considered more sensitive compared to turbidimetric tests, but with the advent of innovative turbidimetric methodologies, such as those utilizing advanced optical instrumentation and sophisticated data analysis techniques, it has become possible to achieve equal sensitivity. As such, immunoturbidimetry is a highly reliable and robust analytical technique that is widely used in various applications, including clinical diagnostics, biotechnology, and biochemistry research.

Turbidimetry is a highly desirable method for various analytical applications due to its numerous benefits. One of the key advantages of turbidimetric testing is that it does not require the use of a dedicated analyzer. These assays can be easily performed using common photometric analyzers, eliminating the need for additional costs associated with purchasing specialized instrumentation or consumables. As a result, turbidimetry is an economical and efficient alternative to nephelometric testing. Furthermore, turbidimetry enables fully automated processing, eliminating the need for time-consuming sample splitting. This feature greatly increases the sample throughput, ultimately improving the overall efficiency of the laboratory. Overall, turbidimetry is a versatile, cost-effective, and efficient methodology that provides accurate results, making it an ideal choice for various analytical applications.
