Imiyoboro yo gukusanya amarasohamwe na anticoagulant muri tube
1 Imiyoboro yo gukusanya amaraso irimo sodium heparin cyangwa lithium heparin: Heparin ni mucopolysaccharide irimo itsinda rya sulfate rifite umuriro mubi, rifite ingaruka zo gushimangira antithrombine III kugirango idakora proteine serine, bityo ikarinda trombine, kandi ikagira ingaruka zo kwirinda nka trombine. guteranya platine.Imiyoboro ya Heparin ikoreshwa muburyo bwihutirwa bwibinyabuzima na maraso, kandi nuburyo bwiza bwo kumenya electrolyte.Mugihe cyo gupima sodium ion mubyitegererezo byamaraso, sodium ya heparin ntigomba gukoreshwa, kugirango bitagira ingaruka kubisubizo.Ntishobora kandi gukoreshwa mukubara leukocyte no gutandukanya, kuko heparin ishobora gutera leukocyte.
2 Amaraso yo gukusanya amaraso arimo EDTA n'umunyu wacyo (EDTA—): EDTA ni aside amine polycarboxylic aside, ishobora gukuramo neza calcium ion mumaraso, kandi calcium ya calcium ikuraho calcium muri calcium.Gukuraho ingingo zifatika bizarinda kandi bihagarike inzira ya coagulation ya endogenous cyangwa hanze, bityo birinde amaraso.Ugereranije n’indi miti igabanya ubukana, ntigira uruhare runini mu guhuza ingirangingo z'amaraso na morphologie y'uturemangingo tw'amaraso, bityo umunyu wa EDTA ukoreshwa.(2K, 3K, 2Na) nka anticoagulants.Ikoreshwa mugupima rusange muri hematologiya, kandi ntishobora gukoreshwa muguhuza amaraso, ibintu bya mikorobe no gupima PCR.
3 Amaraso yo gukusanya amaraso arimo sodium citrate anticoagulant: Sodium citrate igira ingaruka zo kurwanya antikagulant ikora kuri chelation ya calcium ion mu cyitegererezo cyamaraso.Ikigereranyo cya agent n'amaraso ni 1: 9, kandi gikoreshwa cyane muri sisitemu ya fibrinolytike (igihe cya prothrombine, igihe cya trombine, igihe cya trombine igice, fibrinogen).Mugihe cyo gukusanya amaraso, witondere ubwinshi bwamaraso yakusanyijwe kugirango umenye neza ibisubizo by'ibizamini.Ako kanya nyuma yo gukusanya amaraso, bigomba guhindurwa no kuvangwa inshuro 5-8.
4 Irimo citrate ya sodium, intungamubiri za citrate ya sodiumi ni 3,2% (0.109mol / L) na 3,8%, igipimo cya anticoagulant n'amaraso ni 1: 4, ubusanzwe gikoreshwa mugushakisha ESR, igipimo cya anticoagulant ni kinini cyane Iyo ari ni ndende, amaraso aravangwa, ashobora kwihuta umuvuduko wa erythrocyte.
Umuyoboro urimo potasiyumu oxalate / sodium fluoride (igice 1 cya sodium fluoride na 3 bya potassium oxalate): Sodium fluoride ni anticoagulant idakomeye, igira ingaruka nziza mukurinda isukari yamaraso kwangirika, kandi ni uburyo bwiza bwo kurinda isukari yamaraso. .Ugomba kwitondera guhinduranya no kuvanga buhoro mugihe ukoresheje.Ubusanzwe ikoreshwa mugushakisha isukari mu maraso, ntabwo ari ukumenya urea hakoreshejwe uburyo bwa urease, cyangwa no kumenya fosifata ya alkaline na amylase.
Turashobora kuguha ibicuruzwa bijyanye.
