In various other instances, there can be different regions for sample and also elution reagent. Additionally, in many cases, the example can be included with the elution reagent as defined here. The sample is eluted up the strip as well as proceeds down two lanes or separate circulation path 972 as well as 973 as shown by the arrows. The section of the example in lanes or different flow path 972 travels through decomplexation region 921 as well as neutralization region 922 as well as is found at target region 908A. The strip also commonly has control regions 910A and also 910B to ensure that the strip is executing properly. The portion of the example in lane or different circulation course 973 is eluted without experiencing decomplexation and also is discovered at target line 908B.
