Umbhobho wokuqokelela igaziequlethe i-anticoagulant
I-1) I-tube yokuqokelela igazi equkethe i-heparin sodium okanye i-heparin lithium: i-heparin yi-mucopolysaccharide equkethe iqela le-sulfate, kunye nentlawulo enamandla engalunganga, enomsebenzi wokuqinisa i-antithrombin III ukuze ingasebenzi i-serine protease, ngaloo ndlela ikhusela ukubunjwa kwe-thrombin, kunye nokuthintela ukuhlanganiswa kweplatelet kunye ezinye iziphumo ze-anticoagulant.I-tube ye-Heparin isetyenziselwa ukukhangela i-biochemistry engxamisekileyo kunye ne-rheology yegazi, kwaye iyona nto ingcono kakhulu yokubona i-electrolyte.Xa uvavanya i-sodium ion kwiisampuli zegazi, i-sodium ye-heparin ayinakusetyenziswa, ukuze ingachaphazeli iziphumo zovavanyo.Ayinakusetyenziselwa ukubala iiseli ezimhlophe zegazi kunye nokuhlelwa, kuba i-heparin iya kubangela ukudityaniswa kweeseli ezimhlophe zegazi.
I-2) Ukuqokelela imithwalo yegazi equkethe i-ethylenediaminetetraacetic acid kunye netyuwa (EDTA -): i-ethylenediaminetetraacetic acid i-amino polycarboxylic acid, enokuthi isebenze ngokufanelekileyo i-calcium ions egazini.I-calcium ye-chelated iyakususa i-calcium kwindawo yokusabela, eya kuthintela kwaye iphelise inkqubo ye-endogenous okanye exogenous coagulation, ngaloo ndlela ikhusela ukudibanisa kwegazi.Xa kuthelekiswa namanye ama-anticoagulants, inempembelelo encinci kwi-agglutination yeeseli zegazi kunye ne-morphology yeeseli zegazi, ngoko ke, i-Desheng EDTA ityuwa (2K, 3K, 2Na) idla ngokusetyenziswa njenge-anticoagulants.Isetyenziselwa uviwo lwe-hematological ngokubanzi, kodwa kungekhona kwi-blood coagulation, i-trace element kunye noviwo lwe-PCR.
I-3) Iibhubhu zokuqokelela igazi ezine-sodium citrate anticoagulant: i-sodium citrate idlala indima ye-anticoagulant ngokusebenza kwi-calcium ion chelation kwiisampuli zegazi.I-National Committee for Clinical Laboratory Standardization (NCCLS) incoma i-3.2% okanye i-3.8%, kwaye umlinganiselo we-anticoagulant kwigazi ngu-1: 9.Isetyenziswa kakhulu kwinkqubo ye-fibrinolysis (ixesha leprothrombin, ixesha le-thrombin, ixesha elisebenzayo le-thrombin, i-fibrinogen).Xa uthatha igazi, nikela ingqalelo ekuthatheni igazi elaneleyo ukuqinisekisa ukuchaneka kweziphumo zovavanyo.Emva kokuthatha igazi, kufuneka liguqulwe ngokukhawuleza kwaye lixutywe ngamaxesha angama-5-8.
I-4) I-tube ine-potassium oxalate / i-sodium fluoride (i-1 inxalenye ye-sodium fluoride kunye neengxenye ezi-3 ze-potassium oxalate): i-sodium fluoride i-anticoagulant ebuthathaka, inefuthe elihle ekuthinteleni ukuthotywa kwe-glucose yegazi, kwaye iyisigcinalelo esihle kakhulu sokubona i-glucose yegazi. .Xa uyisebenzisa, kufuneka ixutywe ngononophelo ijonge phantsi kancinci.Ngokuqhelekileyo isetyenziselwa ukukhangela iswekile yegazi, kungekhona ukumiselwa kwe-urea ngendlela ye-urease, okanye ukufumanisa i-alkaline phosphatase kunye ne-amylase.
