Claim:
1. A method of assaying for an analyte in a blood sample, the method comprising: (a) applying the sample to a chromatographic strip, the chromatographic strip comprising at least a first pad and a second pad, wherein said first pad is a sample receiving pad which has been treated with a lysing agent to lyse the sample as it flows therethrough, releasing hemoglobin from the sample and the second pad comprises a mixture of dry components; and (b) without prior removal of the hemoglobin from the sample, allowing said sample to flow through the first pad and into the second pad, thereby mobilizing the mixture of dry components, whereby the dry components are reconstituted by contact with the blood sample and a color indicative of the presence or concentration of the analyte is formed at a forward flow front of the chromatographic strip adjacent to a region colored by the hemoglobin from the sample.
