Nkag siab EDTA Blood Collection Tubes: Cov cuab yeej tseem ceeb rau kev kuaj xyuas qhov tseeb

EDTA Tube yog dab tsi?
Lub raj EDTA yog ib lub raj ntim ntshav uas muaj Ethylenediaminetetraacetic acid (EDTA) ua cov tshuaj tiv thaiv coagulant. EDTA ua haujlwm los ntawm kev khi calcium ions hauv cov ntshav, uas yog qhov tseem ceeb rau cov ntshav txhaws. Los ntawm chelating cov ions, EDTA zoo tiv thaiv coagulation, kom ntseeg tau tias cov ntshav tseem nyob hauv nws cov kua dej rau kev tshuaj xyuas.
Cov hlab no feem ntau pom tau los ntawm lawv cov paj ntoo lossis paj yeeb, thiab lawv tau siv dav hauv cov chaw kuaj mob rau kev tshawb nrhiav hematological.
Vim li cas thiaj siv EDTA Blood Collection Tubes?
1. Hematology Tests: EDTA raj feem ntau yog siv rau kev suav cov ntshav (CBC), suav nrog cov qe ntshav liab (RBC), qe ntshav dawb (WBC), hemoglobin, hematocrit, thiab platelet suav. Txij li thaum cov additive khaws cia lub cellular Cheebtsam yam tsis hloov lawv morphology, cov txiaj ntsig yog qhov tseeb thiab txhim khu kev qha.
2. Kev Ntsuas Molecular thiab Genetic: EDTA raj kuj nyiam thaum sau cov ntshav rau DNA thiab RNA tsom xam, xws li PCR-raws li kev soj ntsuam lossis tshuaj pharmacogenetics. Cov tshuaj tiv thaiv coagulant khaws cov nucleic acids zoo vim nws qhov kev ua siab mos ntawm cov hlwb.
3. Ntshav Typing thiab Crossmatching: Cov hlab no pab ua cov ntshav typing thiab sib piv cov txheej txheem los ntawm kev tswj cov ntshav nyob rau hauv lub xeev unclotted.
Qhov zoo ntawm Kev Siv EDTA Tubes
- Kev khaws cia ntawm Cell Morphology: Tsis zoo li lwm cov tshuaj tiv thaiv coagulants, EDTA tswj kev ua haujlwm ntawm cov cellular, uas yog qhov tseem ceeb rau kev kuaj kab mob.
- Kev cuam tshuam tsawg heev: EDTA tsis cuam tshuam nrog feem ntau cov tshuaj biochemical uas cuam tshuam nrog cov qe ntshav.
-Kev ruaj ntseg txuas ntxiv: Cov ntshav kuaj hauv cov hlab EDTA nyob ruaj khov rau ob peb teev, tso cai rau kev thauj mus los yooj yim thiab sijhawm ua haujlwm.
Kev tswj kom zoo thiab kev coj ua zoo tshaj plaws
Txhawm rau kom ntseeg tau tias qhov ua tau zoo ntawm EDTA cov hlab ntim ntshav, ua raws li cov lus qhia hauv qab no:
-Kev txiav txim kom raug ntawm Draw: EDTA raj yuav tsum tau kos tom qab kab lis kev cai ntawm cov ntshav thiab cov hlab ntshav kom tsis txhob hla - cov kab mob sib kis.
- Sib xyaw maj mam: Tam sim ntawd tom qab sau, maj mam tig lub raj 8-10 zaug kom sib tov cov tshuaj tiv thaiv coagulant nrog cov ntshav. Kev tshee tshee yuav ua rau hemolysis.
-Tsis txhob overfilling: Ntshav ntim yog qhov tseem ceeb; overfilled los yog underfilled hlab tuaj yeem cuam tshuam cov txiaj ntsig kev xeem.
- Siv rau Kev Ntsuas Tsuas Yog: EDTA raj tsis pom zoo rau kev tshawb fawb coagulation lossis biochemical kuaj uas xav tau cov ntshav ntshav lossis ntshav tsis muaj EDTA.
Kev hloov tshiab ntawm EDTA Tubes
Niaj hnub nimno EDTA raj tuaj nyob rau hauv ntau qhov ntau thiab tsawg thiab configurations, ib co koom nrog gel separators los pab txhawb plasma sib cais tom qab centrifugation. Cov kev txhim kho no pab ua kom ceev cov kev ua haujlwm hauv chav kuaj thiab tswj cov qauv kev ncaj ncees.
EDTA cov hlab ntshav sau cov hlab ntsha yog cov cuab yeej tseem ceeb hauv cov chaw kuaj mob, tshwj xeeb tshaj yog rau hematology thiab kev kuaj mob molecular. Kev nkag siab txog lawv cov khoom thiab kev siv kom raug ua kom cov txiaj ntsig tau zoo, thaum kawg txhawb kev saib xyuas neeg mob zoo dua. Txawm hais tias koj yog ib tus kws kho mob, kws kuaj mob, lossis ib tus menyuam kawm ntawv, kev paub txog koj tus kheej nrog EDTA raj yuav txhim kho koj txoj kev paub thiab kev txawj ntse hauv kev tswj cov ntshav.
