Iityhubhu zokuqokelela igazikunye ne-anticoagulant kwi-tube
I-1 Iityhubhu zokuqokelela igazi ezine-heparin ye-sodium okanye i-lithium heparin: I-Heparin yi-mucopolysaccharide equkethe iqela le-sulfate kunye nentlawulo enamandla, enempembelelo yokuqinisa i-antithrombin III ukuze ingasebenzi i-serine protease, ngaloo ndlela ikhusela i-thrombin Formation, kwaye ineempembelelo ze-anticoagulant ezifana nokuthintela. ukuhlanganiswa kweplatelet.Iityhubhu ze-Heparin zisetyenziselwa ukukhangela i-biochemical engxamisekileyo kunye nokuhamba kwegazi, kwaye lolona khetho lungcono lokubona i-electrolyte.Xa uvavanya i-sodium ion kwiisampuli zegazi, i-heparin sodium ayifanele isetyenziswe, ukuze ingachaphazeli iziphumo zovavanyo.Kananjalo ayinakusetyenziselwa ukubala i-leukocyte kunye nokwahlula, njengoko i-heparin inokubangela ukuhlanganiswa kwe-leukocyte.
I-2 iibhubhu zokuqokelela igazi eziqukethe i-EDTA kunye neetyuwa zayo (EDTA-): I-EDTA i-amino polycarboxylic acid, enokuthi isebenze ngokufanelekileyo i-calcium ions egazini, kunye ne-calcium e-chelating iyakususa i-calcium kwi-calcium.Ukususwa kwendawo yokusabela kuya kuthintela kwaye kuphelise inkqubo ye-coagulation engapheliyo okanye yangaphandle, ngaloo ndlela ikhusela ukudibanisa kwegazi.Xa kuthelekiswa namanye ama-anticoagulants, ayinayo impembelelo encinci kwi-coagulation yeeseli zegazi kunye ne-morphology yeeseli zegazi, ngoko ke i-EDTA ityuwa idla ngokusetyenziswa.(2K, 3K, 2Na) njengama-anticoagulants.Isetyenziselwa iimviwo ze-hematological ngokubanzi, kwaye ayinakusetyenziselwa ukudibanisa igazi, i-trace elements kunye neemviwo ze-PCR.
I-3 I-tubes yokuqokelela igazi equkethe i-sodium citrate anticoagulant: I-sodium citrate idlala umphumo we-anticoagulant ngokusebenza kwi-chelation ye-calcium ions kwisampuli yegazi.Umlinganiselo we-arhente kwigazi ngu-1: 9, kwaye isetyenziswa kakhulu kwinkqubo ye-fibrinolytic (ixesha leprothrombin, ixesha le-thrombin, ixesha le-thrombin elisebenzayo, i-fibrinogen).Xa uqokelela igazi, nikela ingqalelo kwisixa segazi eliqokelelweyo ukuqinisekisa ukuchaneka kweziphumo zovavanyo.Ngokukhawuleza emva kokuqokelela igazi, kufuneka iguqulwe kwaye ixutywe ngamaxesha angama-5-8.
I-4 Iqulethe i-citrate ye-sodium, i-concentration ye-sodium citrate yi-3.2% (0.109mol / L) kunye ne-3.8%, umthamo we-anticoagulant kwigazi ngu-1: 4, ngokuqhelekileyo isetyenziselwa ukufumanisa i-ESR, umlinganiselo we-anticoagulant uphezulu kakhulu. liphezulu, igazi lihlanjululwe, elinokukhawuleza izinga le-erythrocyte sedimentation.
5 Umbhobho une potassium oxalate/sodium fluoride (1 inxalenye yesodium fluoride kunye neengxenye ezi-3 ze-potassium oxalate): I-sodium fluoride yi-anticoagulant engenamandla, enefuthe elihle ekukhuseleni ukuhla kweswekile yegazi, kwaye iyisilondolozi esihle kakhulu sokubonwa kweswekile yegazi. .Kufuneka kuthathelwe ingqalelo ukuguqula kwaye udibanise ngokucothayo xa usebenzisa.Ngokuqhelekileyo isetyenziselwa ukufumanisa iswekile yegazi, kungekhona ukumiselwa kwe-urea ngendlela ye-urease, okanye ukufumanisa i-alkaline phosphatase kunye ne-amylase.
