Li-tubes tsa pokello ea malie nang le anticoagulant ka har'a tube
1 Li-tubes tsa pokello ea mali tse nang le sodium heparin kapa lithium heparin: Heparin ke mucopolysaccharide e nang le sehlopha sa sulfate se nang le tefiso e matla e mpe, e nang le phello ea ho matlafatsa antithrombin III ho etsa hore serine protease e se ke ea sebetsa, kahoo e thibela thrombin Formation, 'me e na le liphello tsa anticoagulant tse kang ho thibela. kopano ea platelet.Li-tubes tsa Heparin hangata li sebelisoa bakeng sa tlhahlobo ea tšohanyetso ea biochemical le phallo ea mali, 'me ke khetho e ntle ka ho fetisisa ea ho lemoha electrolyte.Ha ho hlahlojoa li-ion tsa sodium ka lisampole tsa mali, sodium ea heparin ha ea lokela ho sebelisoa, e le hore e se ke ea ama liphello tsa liteko.Hape e ke ke ea sebelisoa bakeng sa ho bala le ho khetholla leukocyte, kaha heparin e ka baka leukocyte aggregation.
2 Li-tubes tsa pokello ea mali tse nang le EDTA le matsoai a eona (EDTA—): EDTA ke amino polycarboxylic acid, e khonang ho chelate calcium ions ka katleho maling, 'me chelating calcium e tla tlosa calcium ho tloha k'halsiamo.Ho tlosoa ha ntlha ea karabelo ho tla thibela le ho felisa ts'ebetso ea endogenous kapa extrinsic coagulation, ka hona ho thibela ho kopana ha mali.Ha e bapisoa le li-anticoagulants tse ling, ha e na tšusumetso e fokolang ho coagulation ea lisele tsa mali le morpholoji ea lisele tsa mali, kahoo letsoai la EDTA le atisa ho sebelisoa.(2K, 3K, 2Na) joalo ka li-anticoagulants.E sebelisoa bakeng sa litlhahlobo tse akaretsang tsa hematological, 'me e ke ke ea sebelisoa bakeng sa ho kopanya mali, trace elements le liteko tsa PCR.
3 Li-tubes tsa pokello ea mali tse nang le sodium citrate anticoagulant: Sodium citrate e bapala phello ea anticoagulant ka ho sebetsa ka chelation ea li-ion tsa calcium ka sampuli ea mali.Karolelano ea moemeli ho mali ke 1: 9, 'me e sebelisoa haholo-holo tsamaisong ea fibrinolytic (nako ea prothrombin, nako ea thrombin, nako ea karolo ea thrombin, fibrinogen).Ha u bokella mali, ela hloko palo ea mali a bokelitsoeng ho netefatsa ho nepahala ha liphello tsa liteko.Hang ka mor'a ho bokelloa ha mali, e lokela ho kenngoa le ho tsoakoa ka makhetlo a 5-8.
4 E na le sodium citrate, mahloriso a sodium citrate ke 3.2% (0.109mol / L) le 3.8%, tekanyo ea molumo oa anticoagulant ho mali ke 1: 4, e sebelisoang ka kakaretso bakeng sa ho lemoha ESR, karolo ea anticoagulant e phahame haholo. e phahame, mali a hlapollotsoe, a ka potlakisang sekhahla sa sedimentation ea erythrocyte.
5 The tube e na le potassium oxalate/sodium fluoride (karolo e le 1 ea sodium fluoride le likarolo tse 3 tsa potassium oxalate): Sodium fluoride ke anticoagulant e fokolang, e nang le phello e ntle ho thibela ho senyeha ha tsoekere e maling, 'me ke sebaki se babatsehang bakeng sa ho lemoha tsoekere e maling. .Tlhokomelo e lokela ho nkoa ho khelosa le ho kopanya butle ha u sebelisa.Hangata e sebelisoa bakeng sa ho lemoha tsoekere e maling, eseng bakeng sa ho fumana urea ka mokhoa oa urease, kapa bakeng sa ho lemoha alkaline phosphatase le amylase.
Re ka u fa lihlahisoa tse amanang le tsona.
