Abstract
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).
Claims9
Method for handling blood samples according to which method a blood sample is absorbed into a substrate, a sample piece is taken from the substrate at a point where the blood sample has been absorbed, the sample piece is placed in a vessel, and the sample is dissolved in the vessel in a liquid so that a sample solution is formed in the vessel, characterized in that the sample piece is taken from such a point of the substrate where the blood sample has absorbed through the substrate, the sample piece containing the blood sample is placed in a first vessel where the blood sample is dissolved from the sample piece to the liquid so that a sample solution is formed in the vessel, and the sample solution is transferred to a second vessel which is coated for an analysis and which is transferrable to a measuring instrument for measurement, and wherein the location of the sample piece to be taken from the substrate is determined by observing the substrate from the opposite side of the side from which the blood sample has absorbed into the substrate.
Apparatus comprising a device for taking a sample piece from a point of the substrate onto which a blood sample has been absorbed, and a vessel where the blood sample is dissolved from the sample piece to a liquid so that a sample solution is formed in the vessel characterized in that the apparatus comprises a first vessel in which the blood sample is dissolved from the sample piece to the liquid, and a second vessel into which the sample solution is transferred for an analysis, wherein the apparatus further comprises a detection unit for detecting the location of the blood sample on the substrate from the opposite side of the side from which the blood sample has been absorbed.
Apparatus comprising a device for taking a sample piece from a point of the substrate onto which the blood sample has been absorbed, and a vessel where the blood sample is dissolved from the sample piece to a liquid so that a sample solution is formed in the vessel, characterized in that the apparatus comprises a first vessel in which the blood sample is dissolved from the sample piece to the liquid, and a second vessel into which the sample solution is transferred for an analysis, wherein the apparatus comprises a shaker, which functions as a storage means for the vessel in which the sample piece is dissolved, and a plate storage means where coated vessels for an analysis are situated.
