Koj puas tau khaws daim ntawv qhia txog kev kuaj ntshav, saib cov ntawv thiab cov lej ntawm nws, thiab xav tias, "Qhov no yog dab tsi?"? Tej zaum koj twb pom peb tsab ntawv: WBC, RBC, HGB, PLT, thiab MCV. Nws yog ib qho ib txwm muaj uas yuav xav tias ntxhov siab me ntsis thaum koj pom cov no. Yog li hnub no, cia peb tham txog qhov tseem ceeb tshaj plaws ntawm cov no, MCV, thiab nws hais li cas txog peb txoj kev noj qab haus huv.
Hais yooj yim xwb, MCV yog dab tsi?
MCV sawv cev rau Mean Corpuscular Volume . Nws ntsuas qhov nruab nrab ntawm cov qe ntshav liab hauv koj cov ntshav.
Xav txog nws li no. Peb lub cev raug thauj los ntawm cov tsheb, zoo li cov tsheb thauj khoom. Cov tsheb no yog cov qe ntshav liab. Yog li cov tsheb no tau thauj nrog "khoom" hu ua oxygen thiab xa lawv mus rau txhua lub cell hauv lub cev. Cov pa oxygen no yog qhov tseem ceeb rau peb cov cell kom ua haujlwm thiab nyob.
Yog li ntawd, qhov uas tus nqi MCV ua yog ntsuas qhov nruab nrab ntawm cov "tsheb thauj khoom" no uas khiav ncig koj lub cev. Lawv puas zoo li cov tsheb me me peb lub log? Lawv puas zoo li cov tsheb thauj khoom ib txwm muaj? Los yog lawv puas zoo li cov thawv loj? Qhov no muab lub tswv yim rau peb. Qhov loj me ib txwm ntawm cov qe ntshav liab no yog qhov tseem ceeb heev rau lawv kom thauj cov pa oxygen tau zoo.
Yog tias cov qe ntshav liab me dhau (microcytic) lossis loj dhau (macrocytic), nws tuaj yeem yog ib qho cim qhia txog teeb meem kev noj qab haus huv. Txawm li cas los xij, qee zaum yog tias koj cov qauv ntshav muaj ntau cov qe ntshav liab ntawm ntau qhov loj sib txawv, tus nqi MCV yuav yog qhov qub thaum koj coj tus nqi nruab nrab ntawm lawv txhua tus. Yog vim li cas cov kws kho mob tsis tsuas yog saib tus nqi MCV xwb.
MCV tsuas yog ib feem ntawm qhov kev kuaj loj dua xwb.
MCV tsis yog kev kuaj uas sawv ntawm nws tus kheej xwb. Tus nqi MCV no yog ntsuas thaum lub sijhawm kuaj uas koj feem ntau ua hu ua Kev suav ntshav tag nrho (CBC) . Ib feem ntawm daim ntawv qhia CBC no uas piav qhia txog cov qe ntshav liab hu ua cov ntsuas RBC . MCV yog ib feem ntawm cov ntsuas RBC no.
Muaj ntau lwm yam kev ntsuas tseem ceeb hauv RBC indices. Tus kws kho mob yuav txiav txim siab txog koj cov qe ntshav liab los ntawm kev saib tag nrho cov no ua ke.
| Cov Ntawv Qhia | Tsuas yog lub ntsiab lus |
|---|---|
| MCV (Qhov Nruab Nrab Corpuscular Ntim) | Qhov nruab nrab ntawm cov qe ntshav liab. |
| MCH (Mean Corpuscular Hemoglobin) | Tus nqi hemoglobin uas feem ntau pom muaj nyob rau hauv ib lub qe ntshav liab. Hemoglobin yog cov protein uas nqa oxygen. |
| MCHC (Qhov Nruab Nrab ntawm Corpuscular Hemoglobin Concentration) | Qhov concentration ntawm hemoglobin hauv cov qe ntshav liab (muaj pes tsawg hemoglobin nyob rau hauv tib lub ntim). |
| RDW (Qhov Dav ntawm Kev Faib Tawm ntawm Cov Qog Liab) | Koj cov qe ntshav liab muaj ntau npaum li cas. Puas yog lawv txhua tus loj ib yam, los yog puas muaj ntau cov qe ntshav loj thiab me sib xyaw ua ke ? |
Nco ntsoov tias, tsis muaj kab mob twg tuaj yeem kuaj tau raws li qhov tseeb los ntawm kev saib tus nqi MCV ib leeg xwb. Tus kws kho mob yuav saib tag nrho cov nqi no thiab muab piv rau koj cov tsos mob kom txog thaum xaus.
Kuv yuav tsum ua qhov kev kuaj MCV thaum twg?
MCV yog ib feem ntawm qhov kev xeem CBC tus qauv, yog li koj yuav tau txais kev nyeem yuav luag txhua zaus koj tau txais kev kuaj ntshav.
Txawm li cas los xij, tus kws kho mob yuav txhawj xeeb tshwj xeeb txog qhov txiaj ntsig no:
- Yog tias koj ib txwm xav tias nkees thiab tsis muaj sia nyob.
- Yog tias koj daim tawv nqaij zoo li daj ntseg.
- Yog koj ua pa nyuaj.
- Yog koj muaj cov tsos mob xws li mob taub hau thiab kiv taub hau.
Cov tsos mob no tuaj yeem pom hauv cov mob xws li ntshav tsis txaus . Yog li, tus nqi MCV tseem ceeb heev rau cov xwm txheej zoo li no. Piv txwv li, hauv cov ntshav tsis txaus hlau, tus nqi MCV txo qis. Hauv cov vitamin B12 lossis folate tsis txaus, tus nqi MCV yuav nce ntxiv. Tsis tas li ntawd, hauv cov mob xws li kab mob siab, tus nqi MCV yuav hloov pauv.
Yuav npaj li cas rau qhov kev xeem? Yuav ua li cas thiaj xeem tau?
Qhov no yog ib qho kev kuaj yooj yim heev. Tsis tas yuav npaj tshwj xeeb rau qhov kev kuaj MCV, vim nws yog ib feem ntawm kev kuaj CBC ib txwm muaj. Txawm li cas los xij, yog tias koj tus kws kho mob tau hais kom koj kuaj lwm yam (xws li cov ntshav qab zib) tib lub sijhawm, nws yuav hais kom koj yoo mov ob peb teev. Koj tus kws kho mob yuav qhia koj txog qhov no.
Qhov kev xeem ua tiav li no:
1. Tus kws kho mob lossis tus nais maum yuav xaiv ib qho chaw ntawm koj txhais caj npab uas pom tau cov leeg ntshav meej.
2. Siv ib daim ntaub so cawv los so qhov chaw ntawd.
3. Tom qab ntawd, siv ib txoj hlua roj hmab los khi lub caj npab sab saud me ntsis. Qhov no yuav ua rau cov leeg ntshav pom tseeb.
4. Siv ib rab koob me me, cov ntshav uas xav tau yuav raug rho tawm ntawm cov leeg ntshav mus rau hauv ib lub raj me me. Koj tsuas yog hnov me ntsis chob xwb.
5. Tom qab rho cov ntshav tawm lawm, muab rab koob rho tawm, muab ib daim paj rwb tso rau hauv qhov chaw ntawd, thiab muab ib daim plaster pleev rau.
Tag nrho cov txheej txheem yuav tsum tsis txhob siv sijhawm ntau tshaj tsib feeb. Tom qab ntawd, koj tuaj yeem mus tsev li qub. Ib txhia neeg yuav xav tias kiv taub hau me ntsis, tab sis koj yuav tsum tos kom txog thaum qhov ntawd ploj mus. Koj yuav hnov mob me ntsis thiab tej zaum yuav xiav me ntsis qhov chaw uas cov ntshav tau kos. Qhov no yuav ploj mus tag nrho hauv ib lossis ob hnub. Nws tsis muaj dab tsi yuav tsum txhawj txog.
Cia peb nkag siab txog daim ntawv qhia MCV: Cov lej no txhais li cas?
Tus nqi MCV ntawm koj daim ntawv qhia yog qhia ua tus lej. Nws ntsuas hauv femtoliters (femtoliters - fl) . Koj tsis tas yuav xav ntau txog lo lus ntawd. Qhov tseem ceeb yog tus lej.
Tus nqi MCV nruab nrab rau ib tus neeg laus noj qab haus huv yuav tsum nyob nruab nrab ntawm 80 fl thiab 100 fl.
Tab sis nco ntsoov, qhov ntau thiab tsawg no yuav txawv me ntsis ntawm chav kuaj mus rau chav kuaj, yog li muab piv rau "qhov ntau thiab tsawg ib txwm" uas teev nyob rau hauv koj daim ntawv qhia.
Yog tias tus nqi MCV qis, yuav ua li cas? (MCV qis)
Yog koj tus MCV tsawg dua 80 fl , nws txhais tau tias koj cov qe ntshav liab me dua li qub. Mob no hu ua microcytosis . "Micro" txhais tau tias me.
Tej yam uas ua rau qhov no yog:
- Kab mob ntshav tsis txaus hlau: Qhov no yog qhov ua rau MCV qis thiab feem ntau tshwm sim. Hlau yog qhov tseem ceeb rau kev tsim cov qe ntshav liab. Thaum tsis muaj hlau txaus, cov qe ntshav uas tsim tawm yuav me dua.
- Thalassemia: Qhov no yog ib yam mob uas los ntawm noob caj noob ces. Nws yog tshwm sim los ntawm qhov tsis zoo ntawm kev tsim cov hemoglobin.
- Lwm yam mob uas cuam tshuam nrog hemoglobin.
Yog tias tus nqi MCV siab dua, yuav ua li cas? (MCV siab)
Yog koj tus MCV ntau dua 100 fl , nws txhais tau tias koj cov qe ntshav liab loj dua li qub. Qhov mob no hu ua macrocytosis . "Macro" txhais tau tias loj.
Tej yam uas ua rau qhov no yog:
- Tsis txaus Vitamin B12: Vitamin B12 yog qhov tseem ceeb rau kev faib thiab tsim cov qe ntshav liab kom zoo. Thaum nws tsis txaus, cov qe ntshav yuav tsis faib kom zoo thiab loj dua.
- Tsis muaj folate txaus: Ib yam li vitamin B12, qhov no yog qhov tseem ceeb rau kev tsim cov qe ntshav liab.
- Kab mob siab: Kev ua haujlwm tsis zoo ntawm lub siab kuj yog ib qho ua rau MCV nce ntxiv.
- Kev ua haujlwm tsis zoo ntawm cov pob txha: Piv txwv li, cov mob xws li myelodysplastic syndrome .
- Qee cov kev kho mob chemotherapy rau mob qog noj ntshav kuj tseem tuaj yeem ua rau MCV nce ntxiv ib ntus.
Qhov tseem ceeb tshaj plaws yog, tsis txhob ntshai yog tias koj tus nqi MCV tsis nyob sab nraum qhov ntau thiab tsawg ib txwm muaj. Nws tsuas yog txhais tau tias koj tus kws kho mob yuav tsum tshawb xyuas qhov no ntxiv. Nws tsis yog kev kuaj mob, tab sis tsuas yog ib qho cim qhia uas tuaj yeem pab koj nrhiav tau kab mob.
Koj tus kws kho mob yuav siv tus nqi MCV, nrog rau lwm cov nqi xws li MCH, MCHC, RDW, koj cov tsos mob, thiab lwm yam kev kuaj yog tias tsim nyog, los txiav txim siab qhov tseeb txog koj tus mob. Yog li ntawd, ib txwm qhia koj daim ntawv qhia rau kws kho mob thiab tham txog nws.

- Tus nqi MCV ib txwm muaj rau ib tus neeg laus noj qab haus huv yog ntawm 80-100 fl.
- Tus nqi MCV qis (qis dua 80) tuaj yeem qhia txog cov mob xws li tsis txaus hlau.
- Tus nqi MCV siab dua (saum toj 100) tuaj yeem qhia txog cov mob xws li vitamin B12 lossis folate tsis txaus.
