Abstract: Embodiments include assay devices within a single use, disposable cassette for biochemical assays with at least one fluid well and at least one capillary valve. The capillary valve in combination with motion of porous sheets within the assay leads to addition of liquid reagents at different times to the assay although a user adds the liquid reagents to the cassette simultaneously.

Abstract: In some embodiments, an immunoassay device for detection of recent malaria infection includes: a sample pad positioned adjacent to a first end of a conjugate pad, wherein either the sample pad or the first end of the conjugate pad include a detection complex able to bind anti-ETRAMP5 antibodies; wherein a second end of the conjugate pad includes one or more areas impregnated with a construct protein including ETRAMP5 protein fragments. In some embodiments, the detection complex for anti-ETRAMP5 antibodies includes a capture particle complexed with anti-IgG antibodies. In some embodiments, the detection complex for anti-ETRAMP5 antibodies includes a detection particle complexed with a complex molecule including ETRAMP5 protein fragments.
