Nephelometry test principle
WebAbout 20% of people diagnosed with rheumatoid arthritis have negative RF. Procedure for Rheumatoid Factor Test, Nephelometry Test. An elastic band is wrapped around your upper arm to obstruct the flow of blood. This will help in enlarging the nerve below the band and making it easier to insert a needle into the vein without even feeling a thing. WebTurbidimetry and nephelometry. Turbidimetry and nephelometry are the techniques to measure concentration on the basis of light scatter, as illustrated in Fig. 7.7. Conventional spectrophotometers measure light transmitted at 180 degrees from (or in line with) the incident light source.
