For example, our nucleic acid lateral flow immunoassay, PCRD, is a multiplexed sandwich assay containing two test lines and one control line. The specification of the absorbent pad will have an impact on the volume of sample the test can incorporate.īoth sandwich and competitive assays can be developed to include one or more test lines. The absorbent pad will absorb the excess sample. The sample will pass through the nitrocellulose membrane into the absorbent pad.This is where a rapid test can be combined with a reader to provide quantitative results. Some targets may require quantification to determine target concentration. A coloured line will form and the density of the line will vary depending on the quantity of the target present.
