Txheej txheem cej luam

Alfine cov ntshav sau cov hlab, siv los ua cov ntshav coj mus kuaj, raug txheeb xyuas tus kheej nrog nws cov lej, LOT tus lej thiab hnub tas sij hawm, yog li kev taug qab los ntawm nws qhov chaw tsim khoom rau cov neeg siv khoom kawg yog lav.

Specification

Nta thiab kev siv

Plain tube aims kom tau txais cov qauv kuaj ntshav biochemical, immunological thiab serological xeem hauv kev kuaj mob. Nws lub ntsiab kom zoo dua yog tias cov ntshav tuaj yeem raug cais tawm ntawm cov qe ntshav thiab fibrin, kom nws lub cev thiab tshuaj lom neeg tsis muaj kuab lom. Nws tuaj yeem muab cov qauv kuaj ntshav kom txaus yam tsis muaj kev kis kab mob rau hauv tsev kho mob, thiab ua kom cov ntshav tsis tu ncua nyob rau lub sijhawm tshawb pom ntev. Cov tshuaj ua kom tiav yog tsim nyog rau kev sau cov ntshav thiab khaws cia, biochemical, immunological thiab serological kuaj pom, nrog rau kev kuaj mob ntawm ntau yam kab mob thiab kab mob.

Gel & Clot Activator raj yog tsim thiab ua tiav kom tso cai rau cov ntshav ceev thiab cov ntshav sib cais. Txhua lub raj muaj ib lub gel cais nyob rau hauv lub hauv paus ntawm lub raj. Qhov no ua rau muaj kev cuam tshuam ruaj khov ntawm cov ntshav thiab cov qe ntshav thaum centrifugation. Nyob rau hauv thawj lub raj thiab nyob rau hauv kev pom zoo kuaj mob, tej yam tsis muaj nyob ruaj khov mus txog 48 teev.

Pro-Coagulation raj nrog cov coagulant coated yuav txhawb cov ntshav coagulation tom qab sau. Qhov tsim nyog tus nqi ntawm coagulant ua rau cov ntshav coagulation nyob rau hauv lub sij hawm luv luv, tsis txhob muaj teeb meem hemolysis uas tshwm sim los ntawm cov ntshav txhaws sai heev. Thaum kawg, pob tshab ntshiab tuaj yeem sib cais tom qab centrifugation.

Coagulation raj muaj cov tshuaj buffered sodium citrate, uas yog siv rau kev soj ntsuam cov coagulation tsis. Nws muaj nyob nrog citrate concentration ntawm {{0}}.109mol/l(3.2%) los yog 0.129mol/l(3.8%). Qhov sib tov sib xyaw yog: 1 feem citrate tov rau 9 feem ntshav. Tom qab sau cov ntshav, lub raj ntsuas yuav tsum tig 180 degree thiab nplawm 5-6 zaug.

EDTA raj yog rau kev kuaj ntshav tag nrho hematology. Txhua tsab ntawv sawv cev rau Ethylene Diamine Tetra Acetic acid. Lawv muaj xws li EDTA K2 lossis EDTA K3. EDTA khi cov calciumion thiab yog li thaiv cov coagulation cascade. Erythrocytes, leucocytes thiab thrombocytes nyob rau hauv EDTA anticoagulated ntshav kuaj yog ruaj khov mus txog 24 teev. Peb tsis siv neeg sampling ntsuas finely thiab tshuaj tsuag additives mus rau lub sab hauv raj phab ntsa kom raug, kom lub sib tov ceev thiab cov nyhuv anticoagulation. Hom raj no yooj yim heev rau siv rau nws tuaj yeem tso ncaj qha rau ntawm lub ntsuas ntsuas kom tsis txhob qhib lub hau.

Heparin raj lub hom phiaj kom tau txais cov qauv ntshav plasma, uas yog siv tsis yog rau kev kuaj biochemistry thaum muaj xwm txheej ceev tab sis kuj rau kev kuaj ntshav rheology. Sab hauv phab ntsa ntawm lub raj yog coated nrog tshuaj tsuag qhuav lithium sodium, ammonium los yog heparin. Cov tshuaj tiv thaiv no yog cov tshuaj tiv thaiv coagulants, uas nquag tiv thaiv thrombins, yog li thaiv cov coagulation cascade ntawm cov ntshav kuaj. Lithium Heparin raj kuj tseem muaj nrog cov gel cais, kom tau txais cov qauv ntshav plasma zoo rau kev kuaj biochemistry thaum muaj xwm ceev.

Glucose tube uas sib xyaw ntawm Sodium Fluoride thiab Anticoagulant aims kom tau txais cov ntshav plasma ruaj khov rau kev kuaj ntshav qabzib. Sodium Fluoride yog ib hom inhibitor ntawm qabzib degradation, uas muaj nuj nqi ntawm repressing qabzib metabolism thiab degradation. Kev xaiv Anticoagulant tuaj yeem yog Potassium Oxalate, EDTA thiab Heparin. Lawv tuaj yeem tiv thaiv cov ntshav coagulation thiab zam cov ntshav hemolysis. Qhov kev sib xyaw tshwj xeeb no paub tias cov qauv ntshav qabzib tuaj yeem ua kom txias txias rau lub sijhawm ntev.

ESR raj feem ntau yog siv rau Erythrocyte Sedimentation Rate test. Nws muaj buffered Sodium Citrate tov nrog cov concentration ntawm 3.8 feem pua ​​(0.129mol/L). Qhov sib xyaw ntawm cov ntshav rau Sodium Citrate yog 4: 1. Nws yog qhov tsim nyog rau kev xeem ESR rau cov ncauj lus sib txawv ntawm poj niam txiv neej thiab hnub nyoog, nrog cov coefficient sib piv nrog Westergren txoj kev.
