Abstract
A method for collecting blood while preserving the integrity of the blood sample is provided. The method includes the steps of applying a protective layer to the skin, lancing the skin through the protective layer, allowing blood from the subject to accumulate on the protective layer, and collecting a sample of the blood accumulated on the protective layer. The protective layer may be formed in situ or applied as a tape. In either case, the surface of the protective layer should be hydrophobic.
