Kuaj ntshav xyuas: transcript PDW (cai thiab sib txawv)

Nws yog ib qho nyuaj mus nrhiav ib tug txiv neej uas yeej tsis nyob rau hauv nws lub neej yuav tsis tau ntsib nrog yuav tsum tau mus pub yus cov ntshav suav. Piav PDW nws yuav ua tau kom tsis meej pem. Feem ntau cov yuav, muaj ntau yam ntawm no tsis txawm tau hnov txog. Sau kom tiav cov ntshav count - ib tug yooj yim yam tsawg kawg nkaus ntawm tej kev soj ntsuam thaum lub sij hawm tiv thaiv xeem, ua ntej pib tej kev kho mob kom paub meej tias qhov mob thiab mus sau npe rau cev xeeb tub. Txoj kev tshawb no muaj ib tug kev daim duab ntawm lub xeev ntawm tib neeg noj qab haus huv: inflammatory thiab kab dab, thiab anemia. Yog li ntawd yog dab tsi ntsuas txhais li cas soj ntsuam tsom xam ntawm cov ntshav raws li cov peb lub pob ntseg, thiab tsis yog li ntawd?

Yuav ua li cas yog tso ntshav kuaj?

Ntshav - nws yog ib tug lom kua uas penetrates mus rau hauv txhua txhua cell ntawm tib neeg lub cev. Nws migrates los ntawm peb lub cev, ces nws raws li txoj cai thiab tshuaj indicators, As, koj yuav saib tau npaum li cas zoo rau peb lub cev. Raws li tus tsom xam cov kws kho mob soj ntsuam yuav ua li cas khiav lag luam yog cov no los yog lwm yam kabmob thiab tshuab. Nyob rau hauv cov ntshav, muaj tej yam tshuaj, cov theem ntawm uas yog indicative rau ib tug tshwj xeeb. Cov ntshav yuav npaum li cas capillary thiab venous. Raws li, qhov thawj swb ntawm ib tug ntiv tes, thiab lub thib ob - los ntawm cov hlab ntsha. Feem ntau xeem yog ib qho ntshav kuaj. Muaj ntau ntau lwm yam kev tshawb fawb kev lom kua, qhov twg koj yuav saib tau lub theem ntawm qab zib nyob rau hauv nws, lub xov tooj ntawm tsim nyog cov tshuaj hormones, tus mob ntawm daim siab thiab lwm yam kabmob. Tshwj xeeb tshaj yog xyuam xim rau cov kws txawj ntsuas ntawm hemoglobin nyob rau hauv cov ntshav. Nws yog ib qho tseem ceeb vitally rau ib tug neeg, raws li muab tag nrho cov nruab nrog cev thiab lub hlwb ntawm cov pa, tsis muaj uas hampered ntau yam tshuaj nyob rau hauv lawv.

Yuav ua li cas kuv yuav tsum tau npaj rau nws?

Rau tej laboratory kev ntsuam xyuas yuav tsum tau npaj kom txhij. Kuaj ntshav zoo dua yoo mov rau 8 teev ua ntej ntsuam los ntawm suav los ntawm kev noj haus ntawm cov nqaijrog. Yog xav tau kev txhim khu kev qha tau ua ntej lub xeem yog tsim nyog los txhob haus dej haus cawv. Yuav kom kis tau tus general tsom xam ntawm cov ntshav tshwj xeeb kev cob qhia yog tsis yuav tsum tau, raws li nws yog tuav tsis tau nws. Lwm yam kev kuaj ntshav yuav tsum tau tshwj xeeb kev kho mob ua ntej ntsuam xyuas.

Ntaub ntawv hais txog cov kev kho mob ntawm peb cov ntshav mus kuaj

Lub CBC muaj xws li hemoglobin, qe ntshav dawb thiab cov qauv ntawm cov ntshav liab, ntshav txhaws, erythrocyte sedimentation tus nqi, yog tias yuav tsum tau - hematocrit, xim index, thaum pib thiab thaum xaus ntawm lub coagulation.

Cai ntawm cov ntshav liab nyob rau hauv cov ntshav count yog qhov zoo nkauj ib nrab ntawm cov tib neeg ntawm 4.0 - 5.0, cov neeg sawv cev ntawm lub zog txiv neej pw - 4.5 5.5. Cov tsim ntsiab ntawm tib neeg cov ntshav yog biconcave phaj. Nws muaj sia nyob erythrocyte 110-120 hnub. Tus nab npawb ntawm cov ntshav liab yuav ua tau li qub, siab thiab qis. Ua tus nqi ntawm cov ntshav liab yog hu ua erythrocytosis. Nws tshwm sim tsuas yog nyob rau thooj ntawm cov ntshav, los yog nce tus naj npawb ntawm cov ntshav liab. Txo tus naj npawb ntawm cov ntshav liab yog hu ua erythropenia. Nws yuav tshwm sim tom qab tseem ceeb ntshav poob.

Hemoglobin yog ib feem ntawm ib tug liab ntshav cell. Ntsuas nws nyob rau hauv thiaj li yuav kawm txog cov neeg kawm ntawv ntawm saturation ntawm hemoglobin nyob rau hauv cov ntshav. Nws nyob cov ntshav nrog rau oxygen, thiab chaw pib yog ib qho tseem ceeb rau kev ua pa. Lub hemoglobin theem rau cov txiv neej yog suav tias yog ib qho taw qhia ntawm 120 rau 170 grams tauj ib liter. Rau cov poj niam pom tau hais tias ib txwm hemoglobin theem ntawm 110 rau 150 grams tauj ib liter. Yog hais tias tus neeg mob lub hemoglobin poob, tus mob no yog kho raws li anemia, uas qhia ib tug tsis muaj hlau nyob rau hauv lub cev, thiab vitamin B 12. Nce hemoglobin yog tsis raws li ntau. Nws yuav ua rau cov ntshav txhaws, muaj nws nyob rau hauv ncaws pob nrog erythrocytosis muaj cov neeg nyob rau hauv mountainous thaj chaw.

Leukocytes - yog qe ntshav dawb. Feem ntau, tus xov tooj yog hom twg los ntawm 4 mus rau 9. lawv lub ntsiab muaj nuj nqi - kev tiv thaiv. Nyob rau hauv inflammatory, mob thiab oncological malignancy, qhov no daim duab ntawm lub nce yog hu ua leukocytosis. Yog hais tias cov ntshav dawb tsawg dua li ib txwm, ces tus mob no yog hu ua leukopenia, uas tshwm sim tom qab cov kws khomob, tsis kev tiv thaiv thiab lwm yam pathologies nyob rau hauv lub cev. Tus nqi kuj muaj WBC: qe, uas feem ntau tshwm sim tawm ntawm 45 mus rau 70 feem pua ntawm tag nrho cov leukocytes, lymphocytes, - los ntawm 19 mus rau 37% monocytes, - los ntawm 3 mus rau 10 feem pua, eosinophils - 1-5 feem pua basophils - txog li 1%.

ESR - erythrocyte sedimentation nqi - ib txwm nyob rau hauv cov poj niam sib npaug zos rau ntawm 1 mus rau 15 millimeters ib teev, cov txiv neej nws yog los ntawm 1 mus rau 10 millimeters ib teev. Kom yog feem ntau Schedule ntawm inflammatory, mob thiab oncological kom pom tseeb rau hauv lub cev.

Platelets yog muab kev koom tes nyob rau hauv cov ntshav coagulation system, fibrinolysis. Thrombocytosis los yog nce tus naj npawb ntawm platelets nyob rau hauv ib tug kab tsiaj txhuv tej zaum yuav qhia ntawm ntshav poob cai tom qab tshem tawm ntawm tus po, nrog myeloid leukemia. Thrombocytopenia los tsis platelet suav yog indicative ntawm congenital thiab nrhiav kev txawv txav ntawm hematopoiesis.

Yuav ua li cas yog lub PDW nyob rau hauv cov ntshav mus kuaj?

Nws yog tam sim no lub npe hu rau ntau tshaj nees nkaum ntsuas uas pab tus kws kho mob ua ib qho tseeb xaus txog rau lub xeev ntawm kev kho mob ntawm tus neeg mob. Cov no muaj xws platelet PDW index - cov ntshav mus kuaj, deciphering uas suab zoo li "platelet faib dav rau lawv cov ntsiab lus." Nws characterizes lub heterogeneity ntawm txawv hlwb, xws li hloov lawv loj. Nyob rau hauv lwm yam lus, cov ntshav hlwb muaj ntau ntau thiab tsawg, thiab hais tias lub xov tooj ntawm macro- thiab mikrotrombotsitov qhia no mus kuaj ntshav. Deciphering PDW pab kom paub tias ib tug xov tooj ntawm loj txawv txav nyob rau hauv lub cev.

Ntshav mus kuaj yuav tsum tau noj rau ib qho kev npliag plab los ntawm cov ntiv tes. Tag nrho cov ntshav yog muab tso rau hauv ib txoj kev kuaj tube, uas yog ntxiv ib qho anticoagulant nyob rau hauv ua ntej. Tam sim no, kev tshawb fawb yog nqa tawm nyob rau hauv analyzers, uas nyob rau hauv tas li ntawd mus qhov ntsuas no yuav qhia tau txawm 24. Nws yog ib qho tseem ceeb kom dhau lub CBC. Deciphering PDW nyob ntawm ntau yam, xws li noj mov, overload, cev xeeb tub, hnub ntawm lub cev ntas. Yog li ntawd, koj yuav tsum pub yus cov ntshav nyob rau hauv ib qho kev npliag plab, tshem tawm kev nyuaj siab, hnyav lub cev ua zog, tsis mus nqa tawm kev tshawb fawb thaum lub sij hawm ua poj niam.

Tsis tas li ntawd, muaj yog xws li ib tug tshaj plaws li accounting SD index PDW mus kuaj ntshav. Deciphering lub PDW-SD - Performance index characterizing lub heterogeneity ntawm platelets los ze zog mus rau lub zoo tagnrho tshwm sim raug. SD nyob rau hauv cov ntaub ntawv no - qhov no yog tus txheej txheem sib txawv. Nws coj mus rau hauv tus account nyob rau hauv lub xam ntawm lub Performance index.

Yuav ua li cas koj yuav tsum paub qhov no daim duab?

Nws yog tsis muaj daim card tias nws yog ib qho tseem ceeb heev kom raug txhais kuaj ntshav. Piav PDW muaj ib qho tseem ceeb diagnostic thiab prognostic nqi. Piv txwv li, txoj kev loj hlob npaum li cas yog muab rau tus account nyob rau hauv myelodysplastic kab mob. Nws txawv los ntawm cov cai pub ntau yam ntawm anemia thiab lwm yam mob nyob rau hauv lub cev.

PDW: Yuav ua li cas tus nqi ntawm cov neeg laus?

Nyob rau hauv ib tug ib txwm laus tib neeg platelets yog faib nyob rau hauv volume los ntawm 15-17 feem pua. Qhov no metric cia me deviations - ib mus rau ob feem pua, uas nyob ntawm seb ib tug neeg tus yam ntxwv ntawm lub cev.

Norma index rau cov me nyuam

Thaum lub seev suab ntawm tag nrho cov kev ntsuas ntawm kev soj ntsuam ntshav tsom xam yuav siv sij hawm mus rau hauv tus account tus neeg mob lub hnub nyoog. Nws yog tsis muaj kev zam thiab PDW index - ntshav tsom xam, seev suab, tus nqi rau cov me nyuam yog kwv yees li nyob rau hauv kev sib piv nrog rau lwm cov kev qhia.

Qhov taw qhia PDW yog tseem tsis tau txaus kawm, tab sis nws cov ntaub ntawv yog muab rau tus account ntawm kabke ntawm ntau pathologies, tshwj xeeb yog mob cancer ntawm cov ntshav-sib sau ua nruab nrog cev thiab dab nyob rau hauv cov me nyuam. Salaries, uas yog ib txwm rau cov me nyuam mus txog rau 18 xyoo, xws li los ntawm 10 mus rau 15 feem pua ntawm tag nrho cov xov tooj ntawm cov qe ua ntshav khov.

PDW: Ntshav tsom xam (seev suab). kom ntau ntau ntau

Nqa tawm kev tshawb fawb - qhov no yog tsuas ib nrab ntawm cov sib ntaus sib tua: ib qho tseem ceeb qhov tseeb seev suab ntawm kev kuaj ntshav. Zuag qhia tag nrho PDW tsub kom nrog pathologies xws li:

• inflammatory dab;
• zoo lub cev tom;
• mob ntawm lub siab;
• kab mob plawv;
• splenectomy;
• phem dab, tshwj xeeb tshaj yog nrog metastasis mus rau lub hlwb pob txha;
• mob loj heev cov ntshav poob;
• kuab lom taug txhuas;
• Ntau anemia;
• kev kho mob nrog corticosteroids;
• Alzheimer tus kab mob;
• postoperative lub sij hawm.

Lub cev ntawm PDW saum toj no kev cai txiv neej yuav xav tias malaise thiab tsis muaj zog, kiv taub hau, tej zaum yuav txo tus muaj peev xwm mus ua hauj lwm.

PDW: Ntshav tsom xam (seev suab). txo qib

Nyob rau hauv muaj ntau yam pathologies muab tseeb mob thiab txaus kho mob yuav pab tau txhais xwb tsis nce tab sis kuj txo PDW theem. Downgraded lub Performance index yog nyob rau ntawm:

• leukemia;
• tawg kev mob kev nkeeg;
• myelodysplastic syndrome;
• DIC;
• kab kab mob;
• sepsis;
• thov cytostatics;
• megaloblastic anemia;
• mob npuas paug, kab mob siab.

Nyob rau hauv peb lub sij hawm kom muaj ib tug general tswv yim hais txog ntau yam tseem ceeb heev. Tab sis tseem ceeb tshaj rau suav lawv cov kev paub txaus. Muaj ib lub tswv yim thiab ib tug profound kev txawj ntse - tsis yog tus qub tshaj plaws. Yog li ntawd, peb yuav tsum to taub hais tias lub PDW - ntshav tsom xam, seev suab, tus nqi thiab tus nqi ntawm uas yog cov zoo-paub xwb los ntawm ib tug tshwj xeeb. Txiv neej nws tus kheej tsis muaj kev tshawb pom ntawm cov kev tshawb fawb thiab cov kev kawm yuav tsum tsis txhob ua, koj yuav tsum mus rau lub tsev kho mob.
