The present invention provides a blood coagulation promoter capable of exerting both excellent blood coagulation promoting ability and excellent blood clot detaching ability; and a blood collection tube accommodating the blood coagulation promoter. The present invention provides a blood coagulation promoter which includes a hardly water soluble polyoxyalkylene derivative; a partially saponificated polyvinyl alcohol; at least one substance selected from the group consisting of adsorptive inorganic substances and hydrolases capable of hydrolyzing a bond between Arg and an arbitrary amino acid reside and/or a bond between Lys and an arbitrary amino acid residue in a peptide chain; a polyvinylpyrrolidone; and preferably a water-soluble silicone oil, and a blood collection tube in which the blood coagulation promoter is accommodated in a tubular vessel having a bottom.

A Plasma or serum separation membrane that enables omitting centrifugal separation, is free from hemolysis attributed to destruction of red blood cells and realizes easy and rapid separation of plasma or serum from blood; and a filter apparatus including the plasma or serum separation membrane. In particular, a plasma or serum separation membrane being a membrane for separation of plasma or serum from blood and having a void ratio of 30% or below; and a filter apparatus comprising a filter member capable of attaining movement of plasma swifter than movement of blood cells and a plasma or serum separation membrane connected in series with a rear side of the filter member.

A method for filtrating liquid sample such as blood or the like with a filter member utilizing inner vacuum, the same enabling completion of filtration without removing a stopper, and superior in safety and being free from contamination. In collecting and filtrating the liquid sample using a sample collection vessel, in which a sample-collecting partcontaining a filter memberis inserted in a vacuumed sample-storing part, the sample storing partand sample-collecting partare air-tightly sealed with a stopper, the liquid sample such as blood or the like collected in the sample-collecting partis filtrated by the filter member. When the filtration stops, a hollow needleis pierced through the stopperand thus the sample-collecting partis communicated with atmosphere, thereby the pressure in the sample-collecting partbeing enhanced upper than in atmosphere to enable the filtration again.

A blood test containerhaving a closed-bottom tubular container, a closed-bottom second tubular container having a diameter smaller than that of the tubular containerfor accommodation therein, and a blood test reagentsecured onto at least one of an inner face of the tubular container and an outer face of the second tubular container. A blood test method comprising, in sequence, introducing blood into any one of the aforementioned blood test containersand allowing the blood or its component to contact the blood test reagent

Blood test container

A blood test container which facilitate the procedures starting from blood collection and ending with measurement of various components present in the blood while eliminating a risk for a tester to come into contact with the blood. A blood test container 1 having a closed-bottom tubular container 2, a closed-bottom second tubular container having a diameter smaller than that of the tubular container 2 for accommodation therein, and a blood test reagent 3 secured onto at least one of an inner face of the tubular container and an outer face of the second tubular container.

The invention provides a serum or plasma separating composition which comprises a cyclopentadiene resin, a viscosity adjusting agent and an organic gelling agent. The composition is characterized in that the cyclopentadiene resin is a liquid resin at a temperature of 25.degree. C., the viscosity adjusting agent being a liquid ester obtained from propionic acid, butyric acid, benzoic acid or phthalic acid, the organic gelling agent being a condensation product of sorbitol and an aromatic aldehyde, the composition containing 0.8 to 25 parts by weight of the viscosity adjusting agent and 0.03 to 0.9 part by weight of the organic gelling agent per 100 parts by weight of the cyclopentadiene resin. The composition forms a satisfactory separating layer even when subjected to a centrifugal separation operation at a set temperature of 4.degree. C.
