Advantage Leptospira IgM & IgG card test is based on Immunochromatographic assay principle. The test sample is introduced to and flows laterally through an absorbent pad where it mixes with the conjugate. If the sample contains Leptospira specific IgM and/or IgG antibodies, it forms a complex with the conjugate. The complex then migrates through the nitrocellulose membrane by capillary action. When the complex meets the immobilized antibodies (Test line ‘M & G’), it generates a red line, indicating that the sample is reactive. To serve as a procedural control, an additional control line ‘C’ has been immobilized at a distance from the test line on the strip. If the test is performed correctly, this will result in the formation of a red line at the control region upon contact with the conjugate.
