PURPOSE:To obtain a blood separation tube for sampling plasma which enables accurate measurement of the coagulation time in the diagnosis of blood agglutination troubles by arranging a thixotropic separating agent with the specific gravity intermediate between plasma and a blood cell component and an anti-blood agglutination agent provided into blood dispersably in contact therewith in a bottomed blood sampling tube. CONSTITUTION:In the inspection of an agglutination of blood, a thixotropic separating agent 15 with the specific gravity intermediate between plasma and a blood cell component is placed on the bottom of the body 11 of a blood sampling tube 10 while an anti-blood agglutination agent 12 is put on a separating agent 15 and a puncturable plug 14 made of butyl rubber or the like is applied to enable the holding the inside of the body 11 at a negative pressure. The blood sampling tube 10 uses a blood sampling needle 17 on a blood sampling holder 16 to sample blood from a patient. After the sampling of the blood, the tube is tilted to mix and a centrifugal separation is performed to separated a plasma layer 18 on the separating agent 15 and a blood cell layer 19 thereunder. After the separation, components of the layers 18 and 19 is kept from being mixed during the preservation and transportation with dispersion of the anti- agglutination agent 12 thereby facilitating the withdrawal of plasma only. Thus, plasma component can be used for inspection of agglutination to obtain a sample allowing an easy and accurate diagnosis of blood agglutination troubles. |
