ELITex Bicolor RF and Waaler Rose Brochure

Product catalog summary

Overview: The document describes two complementary slide agglutination tests, ELITex Bicolor RF and WAALER-ROSE Bicolor, designed for the rapid qualitative or semi-quantitative detection of IgM Rheumatoid Factor in serum. These tests are characterized by easy-to-read bi-colored reactions, complete kits with controls, a simple and fast protocol, cost-effectiveness, and long shelf life.

Specifications:

ELITex Bicolor RF: Sensitivity of 98.75% with a threshold of approximately 8 IU/mL and specificity of 98.37%.
WAALER-ROSE Bicolor: Sensitivity of 98.79% with a threshold of approximately 8 IU/mL and specificity of 98.79%.

Methodology: The principle involves latex particles (ELITex Bicolor RF) or red blood cells (WAALER-ROSE Bicolor) sensitized by gamma-globulins. When added to the serum, the presence of Rheumatoid Factor causes agglutination, visible as a bi-colored reaction. The procedure involves adding serum or controls, adding a drop of test reagent, and observing the reaction after a slow rotary motion for 2 minutes.

Interpretation of Results:

Positive Reaction: ELITex Bicolor RF shows red agglutinates on a blue background, while WAALER-ROSE Bicolor shows brown agglutinates on a blue background, indicating the presence of Rheumatoid Factor.
Negative Reaction: ELITex Bicolor RF results in a homogeneous purple suspension, and WAALER-ROSE Bicolor results in a homogeneous green-brown suspension, indicating the absence of Rheumatoid Factor.

Additional Information: The document provides contact information for ELITechGroup across various regions, emphasizing the availability of tailored solutions for quantitative determination of Rheumatoid Factor and detection and elimination of interferences.

SEROLOGY RAPID TESTS ELITex Bicolor RF - WAALER-ROSE Bicolor Latex particles (ELITex Bicolor RF) or Red Blood Cells (Waaler-Rose Bicolor) are sensitized by gamma-globulins (Human IgG for ELITex Bicolor RF / Animal IgG fraction for Waaler-Rose Bicolor) and added to the tested serum. If Rheumatoid Factor is present in the serum, it will agglutinate and be revealed by an easy-to-read bi-colored reaction. 2. Add one drop of Test Reagent 3.
