The RF Fast Test Kit is based on advanced immunofluorescence technology, enabling the quantitative determination of rheumatoid factor (RF) with high precision. RF is an autoantibody that targets the Fc fragment of human or animal denatured IgG molecules and is primarily of the IgM type, which this kit detects.

This assay is an important diagnostic tool for rheumatoid arthritis, helping distinguish autoimmune inflammation from other causes of joint pain. Its short testing time and simple workflow make it ideal for clinical laboratories, hospitals, and point-of-care settings, ensuring fast and reliable results for early detection and patient management.
