What is the turbidimetric method?

turbidimetry, in analytical chemistry, methods for determining the amount of cloudiness, or turbidity, in a solution based upon measurement of the effect of this turbidity upon the transmission and scattering of light.

What does turbidimetry mean?

Medical Definition of turbidimetry : the determination and measurement of the concentration of suspended matter in a liquid by use of a turbidimeter.

What is immuno turbidity?

A method that measures the absorbance of light from a sample which is used for quantifying an amount of analyte based on the level of turbidity produced by the formation and precipitation of an immune complex containing the analyte. ( NCI Thesaurus)

Is turbidimetry a principal?

Principal :- Turbidimetry is concerned with the measure of the intensity of the transmitted light as a function of concentration of the suspended particle in a suspension. The intensity of transmitted light is measured in a line i.e 180° to the incident light. Hence concentration is more transmission is less.

Which of the following can be determined by turbidimetric?

Turbidimetry measures the cloudiness or turbidity of a solution.

What does NTU measure?

NTU stands for Nephelometric Turbidity unit, i.e. the unit used to measure the turbidity of a fluid or the presence of suspended particles in water. The higher the concentration of suspended solids in the water is, the dirtier it looks and the higher the turbidity is.

What is quantitative Immunoturbidimetry?

A quantitative immunoturbidimetric assay for rheumatoid factors (RF) is described, based on the immunoprecipitation between aggregated human IgG and rheumatoid factors in serum. The resulting turbidity is measured photometrically at 340 nm.

What is the use of turbidimeter?

Turbidimeters are used to measure the relative clarity of a fluid by measuring the amount of light scattered by particles suspended in a fluid sample.

Why is turbidimetry used?

Turbidimetry (immunoturbidimetry) and nephelometry (immunonephelometry) measurements are commonly used to quantify immune-complex precipitates by their ability to interact with incident light.

How does a turbidimeter work?

A turbidimeter measures the suspended particles with a light beam (beam source) and a light detector set at 90 ° from the original beam. The amount of light reflected for a given density of particles depends on the properties of particles such as their shape, color and reflectivity.

What are the advantages of turbidimetric method?

Turbidimetry has the advantage of being fast and non-destructive. Therefore, the determination of the turbidity, or optical density (OD), of liquid cultures may be considered the most widespread analytical tool to monitor the growth of pure bacterial cultures.

Which is an instrument used to measure the turbidity of liquids?

1 : an instrument for measuring and comparing the turbidity of liquids by viewing light through them and determining how much light is transmitted. 2 : nephelometer.

What are the parameters of turbidimetric blood test?

The following three parameters were measured from the urine sample using their corresponding methods: urinary calcium by o-cresolphthalein complex method, [9] urinary creatinine by modified Jaffe’s method, [9] and urinary protein by turbidimetric method.

How is rheumatoid factor ( RF ) measured by turbidimetry?

CRP and rheumatoid factor (RF) were measured using turbidimetry with normal range 0-5 mg/l and < 14 IU/ml, respectively. CRP was done by Turbidimetry. LFT was done by fully automated analyser. Sulphate contents were determined by turbidimetry as BaSO4. The serum hs-CRP levels were measured by latex turbidimetry method.
