Method for handling blood samples (32) wherein a blood sample is absorbed into a filter paper (30) and a sample piece (36) is taken from the filter paper from the opposite side of the absorption side. The sample piece is placed in a sample well of an uncoated micro titration plate (45) and is dissolved in a liquid so that a sample solution is formed in the well. The sample solution is transferred to a second micro titration plate (52-54) coated for the analysis. The apparatus comprises a camera (43), which identifies the filter paper (30), locates the blood sample (32), and informs the punch (47) of the location of the sample. The filter paper (30) is placed in a package, (22) having openings (25) for absorbing and punching of the sample and the covering (23) is provided with a bar code (29).
