Sometimes, a one step addition of a combination of sample as well as elution reagent can be made at 520 or 523. A fluid nonporous membrane layer 570 which has good warm transfer features can be utilized to permit transfer of heat without subjecting the sample to the exothermic salts. The membrane 570 can likewise be a membrane that allows the passage of water right into the salts below, however does not allow passage of the larger elements of the example and eluent solutions, such as antibodies or target proteins or nucleic acids. In many cases the lateral circulation test strip of more makes up a neutralization area making up reducing the effects of agents that neutralize the decomplexation reagent. In some cases the lateral flow test strip better makes up an elution reagent application region on the strip upstream of the example application area. In some cases the strip is set up such that the elution reagent combined with the sample is added to the sample application area of the strip. In some cases the decomplexation region comprises an acidification reagent that lowers the pH of the sample as the sample travels through the decomplexation area.

Sometimes the acidification reagent brings the pH of the sample to much less than regarding 5. In some cases the acidification reagent brings the pH of the example to less than about 4. In many cases the acidification reagent brings the pH of the example to less than regarding 3. Various conditions need dimensions of targets which might normally be inaccessible because of complexation, which may be complicateds of antibodies and also RNA or antibodies as well as proteins, as occurs with HIV P24 RNA assays as well as with Dengue fever NS1 healthy protein assays. The binding of the antibody may render the target not available, as the target area might coincide for a capture or label antibody and the antibody with which the target is complexed. It might thus be preferable to interrupt or otherwise trigger disassociation of facilities of target moieties. An advantage of fluorescence over absorbance systems is the dark and consistent history that is attained by reliable barring of the excitation light.
