What is Rose waaler test?
Rose-waaler is a haemagglutination slide test for the rapid qualitative and semi-quantitative détection of IgM Rheumatoid Factor in human sera. The test is used for the detection of Rheumatoid Factor (RF) in human serum.
What is 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 is quantitative Immunoturbidimetric method?
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 RA factor normal range?
The RA factor normal range is below 14 IU/ml for the Rheumatoid factor. Any values about 14IU/ml or above are considered high.
What does positive rheumatoid factor indicate?
A positive rheumatoid factor test result indicates that a high level of rheumatoid factor was detected in your blood. A higher level of rheumatoid factor in your blood is closely associated with autoimmune disease, particularly rheumatoid arthritis.
What is RA factor?
Rheumatoid factor (RF) is an immune system protein that attacks healthy cells in the body. High RF levels in the blood can indicate an autoimmune condition, such as rheumatoid arthritis. An RF test is a blood test that can help diagnose rheumatoid arthritis.
What is turbidimetric analysis in analytical chemistry?
[¦tər·bə·də¦me·trik ə′nal·ə·səs] (analytical chemistry) A scattered-light procedure for the determination of the weight concentration of particles in cloudy, dull, or muddy solutions; uses a device that measures the loss in intensity of a light beam as it passes through the solution.
Which enzyme is measured by turbidimetric method?
trypsin
A turbidimetric method for measuring the activity of trypsin and its inhibition. Anal Biochem.
What is Immunoturbidimetric assay?
Abstract. Immunoturbidimetry is a suitable technique for the determination of urinary proteins in clinical laboratories. We have developed immunoturbidimetric assays for the measurement of urinary albumin and transferrin which are adapted for the Cobas-BIO centrifugal analyzer.
What is particle enhanced Immunoturbidimetric?
Particle-enhanced immunoturbidimetric tests are especially useful if an antigen is present in low concentration. By this approach, microscopic particles enlarge the formed immune complexes, amplify the signal and thereby lead to a significantly increased sensi- tivity of this method.
