vim li cas cov plasma tsis sib cais hauv lub centrifuge

Kev Taw Qhia

Kev siv centrifugation yog ib txoj kev siv hauv chav kuaj uas siv dav los cais cov khoom sib txawv ntawm qhov ceev. Nws siv lub hauv paus ntsiab lus ntawm lub zog centrifugal los cais cov khoom hauv ib qho sib tov. Txawm li cas los xij, hauv cov ntshav, kev siv centrifugation tsis ua rau muaj cov khaubncaws sab nraud povtseg lossis kev sib cais sib txawv. Tsab xov xwm no tshawb nrhiav cov laj thawj tom qab plasma tsis tuaj yeem sib cais hauv lub centrifuge thiab qhia txog cov yam ntxwv tshwj xeeb ntawm cov khoom tseem ceeb ntawm cov ntshav no.

Kev Nkag Siab Txog Plasma

Plasma, cov kua ntawm cov ntshav, muaj dej, electrolytes, proteins, hormones, thiab ntau yam tshuaj. Nws ua lub luag haujlwm tseem ceeb hauv kev tswj hwm homeostasis hauv lub cev los ntawm kev thauj cov as-ham, hormones, thiab cov khoom pov tseg. Plasma kuj nqa cov tshuaj tua kab mob thiab pab tswj cov ntshav siab. Kev nkag siab txog cov khoom sib xyaw thiab cov khoom ntawm plasma yog qhov tseem ceeb rau kev tshawb pom vim li cas centrifugation tsis ua rau nws sib cais.

Viscosity thiab Density ntawm Plasma

Plasma qhia txog cov yam ntxwv tshwj xeeb uas cuam tshuam kev sib cais hauv lub centrifuge. Ib qho ntawm cov yam ntxwv no yog viscosity. Viscosity txhais tau tias cov kua dej tsis kam rau kev ntws. Plasma muaj viscosity qis, zoo ib yam li dej. Tsis zoo li lwm cov khoom hauv cov ntshav, plasma tsis muaj qhov ceev siab uas yuav ua rau nws sib cais tau zoo. Yog li ntawd, thaum raug rau lub zog centrifugation, plasma tsis ua tiav cov txheej sib txawv.

Kev sib npaug ntawm Plasma

Plasma yog ib qho chaw nruab nrab uas sib xws, txhais tau tias nws cov khoom sib xyaw ua ke tseem sib xws thoob plaws. Tsis zoo li cov tshuaj ncua, uas muaj cov khoom sib txawv uas tawg ua kua, plasma tsis muaj cov khoom pom. Nws feem ntau muaj cov ions, cov protein, thiab cov kuab tshuaj uas tsim cov khoom sib xyaw ua ke. Thaum centrifuged, qhov sib xws tiv thaiv kev tsim cov txheej lossis kev sib cais.

Tsis Muaj Pellets Los Yog Sediments

Kev siv lub tshuab centrifugation yog siv txoj kev sib cais cov khoom me me raws li lawv qhov ceev. Hauv cov ntshav, cov qe ntshav liab thiab cov qe ntshav dawb muaj qhov ceev dua li cov plasma thiab tuaj yeem sib cais tau zoo los ntawm kev siv lub tshuab centrifugation. Cov qe ntshav no tsim cov pellets lossis cov av nyob hauv qab ntawm lub raj vim lawv qhov ceev dua. Txawm li cas los xij, plasma tsis muaj cov khoom me me lossis cov av zoo li no, vim nws feem ntau nqa cov tshuaj yaj. Yog tsis muaj cov khoom me me no, cov txheej txheem centrifugation tsis ua tiav kev sib cais lossis kev tsim cov txheej.

Lub Luag Haujlwm ntawm Anticoagulants

Lwm yam uas ua rau cov ntshav tsis sib cais yog siv cov tshuaj anticoagulants. Yuav kom tau cov ntshav rau ntau yam kev kuaj hauv chav kuaj, feem ntau cov ntshav raug sau rau hauv cov raj uas muaj cov tshuaj anticoagulants. Cov tshuaj anticoagulants tiv thaiv cov ntshav kom tsis txhob txhaws, vim lawv tiv thaiv cov yam tseem ceeb uas ua rau cov ntshav txhaws. Yog li ntawd, cov ntshav tseem nyob hauv nws daim ntawv ua kua, tiv thaiv cov ntshav kom tsis txhob sib cais ntawm nws cov khoom hauv lub cev.

Xaus lus

Txawm hais tias centrifugation yog ib txoj kev zoo rau kev sib cais cov khoom nrog cov ntom sib txawv, plasma ua rau muaj kev cov nyom tshwj xeeb vim nws cov khoom thiab cov khoom sib xyaw. Plasma qhov viscosity qis, homogeneity, tsis muaj cov khoom ntom dua, thiab muaj cov tshuaj anticoagulants cuam tshuam nws txoj kev sib cais siv cov txheej txheem centrifugation. Kev nkag siab txog cov yam ntxwv no pab cov kws tshawb fawb thiab cov kws kho mob siv cov txheej txheem tsim nyog los cais cov plasma thiab kawm nws cov khoom sib xyaw kom zoo.
