Ọbara nchịkọta tubenwere anticoagulant
1) tube mkpokọta ọbara nwere heparin sodium ma ọ bụ heparin lithium: heparin bụ mucopolysaccharide nwere sulfate otu, nke nwere ụgwọ na-adịghị mma, nke na-arụ ọrụ nke ike antithrombin III na-egbochi serine protease, si otú ahụ na-egbochi guzobe thrombin, na-egbochi nchịkọta platelet. mmetụta anticoagulant ndị ọzọ.A na-ejikarị tube heparin eme ihe maka nchọpụta biochemistry mberede na rheology ọbara, ọ bụkwa nhọrọ kacha mma maka nchọpụta electrolyte.Mgbe ị na-anwale ion sodium na nlele ọbara, a pụghị iji sodium heparin mee ihe, ka ọ ghara imetụta nsonaazụ ule.A pụghịkwa iji ya mee ihe maka ọnụ ọgụgụ nke mkpụrụ ndụ ọbara ọcha na nhazi ọkwa, n'ihi na heparin ga-eme ka nchịkọta ọbara ọcha dị ọcha.
2) Ịnakọta arịa ọbara nwere ethylenediaminetetraacetic acid na nnu ya (EDTA -): ethylenediaminetetraacetic acid bụ amino polycarboxylic acid, nke nwere ike chelate calcium ion n'ime ọbara nke ọma.Calcium chelated ga-ewepụ calcium site na ebe mmeghachi omume, nke ga-egbochi ma kwụsị njedebe njedebe ma ọ bụ exogenous coagulation usoro, si otú a na-egbochi ọbara coagulation.E jiri ya tụnyere ọgwụ mgbochi ndị ọzọ, ọ na-enwechaghị mmetụta na agglutination nke mkpụrụ ndụ ọbara na morphology nke mkpụrụ ndụ ọbara, Ya mere, Desheng EDTA salts (2K, 3K, 2Na) na-ejikarị eme ihe dị ka anticoagulants.A na-eji ya maka nyocha ọbara ọbara n'ozuzu, mana ọ bụghị maka coagulation ọbara, ihe nchọta na nyocha PCR.
3) Ọbara na-anakọta tubes nwere sodium citrate anticoagulant: sodium citrate na-arụ ọrụ mgbochi ọbara site n'ime ihe na calcium ion chelation na nlele ọbara.Kọmitii Mba maka Clinical Laboratory Standardization (NCCLS) na-atụ aro 3.2% ma ọ bụ 3.8%, na oke nke anticoagulant na ọbara bụ 1:9.A na-ejikarị ya na usoro fibrinolysis (oge prothrombin, oge thrombin, oge thrombin na-arụ ọrụ, fibrinogen).Mgbe ị na-ewere ọbara, ṅaa ntị n'inweta ọbara zuru oke iji hụ na nsonaazụ ule ziri ezi.Mgbe ị nwetasịrị ọbara, a ga-atụgharị ozugbo wee gwakọta ya ugboro 5-8.
4) The tube nwere potassium oxalate/sodium fluoride (1 akụkụ sodium fluoride na 3 akụkụ potassium oxalate): sodium fluoride bụ ihe na-adịghị ike anticoagulant, na-enwe mmetụta dị mma n'igbochi mmebi nke glucose ọbara, na ọ bụ ihe nchebe magburu onwe ya maka nchọpụta glucose ọbara. .Mgbe ị na-eji ya, ekwesịrị iji nlezianya gwakọta ya n'elu ala nwayọọ nwayọọ.A na-ejikarị ya eme nchọpụta glucose ọbara, ọ bụghị maka mkpebi urea site na usoro urease, ma ọ bụ maka nchọpụta alkaline phosphatase na amylase.
