The β2-Microglobulin (β2-M) ELISA is a highly sensitive enzyme-linked immunosorbent assay designed for the quantitative measurement of β2-microglobulin levels in serum, plasma, or urine samples. Elevated levels of β2-microglobulin are associated with various conditions, including kidney disease, multiple myeloma, and certain viral infections. This test provides accurate and reliable results, helping healthcare professionals monitor disease progression and response to treatment. Ideal for clinical and research settings, it offers a non-invasive and efficient method for assessing renal function and immune system activity.
