Abstract
A method for verifying the effectiveness of a washing operation on a clinical dry chemistry slide element in which wash liquid is dispensed onto the surface of the slide element and then detection devices are used to verify the effectiveness of the wash by making an initial detection at an on center site followed by making a second detection at a second and off-center radial position. A comparison of the two readings provides verification of the wash. In addition, rate measurements can be made at each of the read positions to measure the effectiveness of the wash and to verify sample application for immunological assays.
