Abstract: The invention relates to diagnosis of reactive conditions, such as malignant tumors. According to the invention, the amount of cellular fibronectin in a body fluid is determined, and an elevated amount is used as a marker for a reactive condition. The method is especially suitable for the diagnosis of carcinomas, such as colon carcinoma.

Abstract: The invention concerns an immunological assay system, wherein the inner face of the cuvettes is used as the solid phase. The equipment includes a displaceable carriage (8) for the cuvette set as well as, above the carriage, a dosage head (9), to which the liquid dosimeter (11) and the measurement device (19) are attached. All the operations take place automatically.

Abstract: Method and apparatus for the measurement of properties of a liquid present in a vessel (2), for example for the measurement of the absorbance of a liquid, of the properties of an agglutination, precipitate (4) or any other reaction result placed on the bottom of a vessel, by means of radiation and of a detector (3) receiving radiation while the vessel moves along with a rotor revolving around the vertical axis (15) of a centrifuge. Thereby the beam of measurement (5) coming from the source of radiation (1) passes substantially horizontally and the intensity of the radiation passing through, or reflected from, the contents of the vessel is measured.

Abstract: A method for the detection of hemoglobin or decomposition products of hemoglobin in feces. Human hemoglobin is isolated from the sample by means of an immunological reaction, i.e. a reaction between an antibody and an antigen, by using an antibody specific for human hemoglobin and attached to the solid phase. The human hemoglobin bound to the antibody is established hereupon.

Abstract: A method and apparatus for washing the solid annular pieces used in immune methods, i.e. the so-called EIA-rings, and for coating such rings with a reagent, as well as for the dispensing of the rings. The EIA-rings are fitted, one after the other, into a tubular container part, which is open at both ends. To the bottom end of the container part an intake tip is attached, and to the other end a device for drawing and exhausting a liquid through the intake tip into the container part. The container part enclosing the EIA-rings is then sealed at both ends until the upper end of the container part is opened for dispensing the rings. The opened end is connected to a dosage device, the intake tip of the container part is removed and the EIA-rings are dispensed by means of the device.

Abstract: There is disclosed a micro-cuvette unit comprising a plurality of components in the form of a matrix which is arranged so that the cuvettes may be handled as one unit. The structural body of the micro-cuvette unit comprises a rectangular frame which is designed so that a plurality of cuvette components may be fitted to the frame, one after another. Each cuvette component comprises a plurality of cuvettes arranged in the form of a line or matrix and connected to each other directly or by means of support discs. The frame part of the micro-cuvette unit is open in the middle, at least within the area covered by the cuvettes in the cuvette components. The frame part contains two opposite sides which are provided with connecting means for joining the cuvette components to the frame part.
