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.

A process for preparing a purified syphilis antigen which comprises adsorbing an extract originated from Treponemda pallidum on a hydroxyapatite gel, followed by elution, while an aqueous medium is used.

Process for preparing a purified treponemal antigen and use thereof

A process for preparing a purified syphilis antigen from Treponema pallidum is presented. The process comprises the steps of obtaining an extract from Treponema pallidum, adsorbing the extract onto hydroxyapatite gel and eluting the antigen in the presence of a surfactant. The preferred surfactant is octylglucopyranoside, A diagnostic agent is prepared which comprises the purified syphilis antigen adsorbed on an inert carrier, which carrier at least partially a hydrophobic carrier to which the antigen is adsorbed.
