'''Rapid Vertical Flow-through tests''' are a type of diagnostic assay that allows users to test for the presence of a biomarker, usually a specific [[antibody]], in a sample such as blood. Detection of a specific biomarker aids in the diagnosis of and allows therapeutic action to be initiated quickly. The field of applications for this technology is wide, whereas generally all applications applying [[lateral flow test]]s can be replaced by flow-through assays. Commercial applications mainly target testing for infectious disease, both by viruses (e.g. [[HIV]], [[Hepatitis C]], [[Hepatitis B]] <ref name="medmira">http://medmira.com/products</ref>
) or bacteria (e.g. [[Syphilis]]<ref name="medmira_a">http://medmira.com/products</ref>
or [[Helicobacter pylori]] <ref name="medmira_b">http://medmira.com/products</ref>).
