MCV (he whakamātautau toto): tuhinga. MCV: täkupu

Counting te maha o ngā pūtau ngeniwhero ki te whakatau i to ratou rōrahi toharite ranei tātari toto i roto i te taha ki e whakamahia atu rangahau mo te tātaritanga pārōnaki o ngā ngā o anemia me ētahi atu tikanga pathological.

He aha te mea te pūtau toto whero

E ai ki nga āhuatanga o erythrocytes (pūtau toto whero), e he tino motuhake pūtau kore-karihi, biconcave āhua toto, he reira taea ki te whakawa i te āhua o te hauora o te tangata. Ko te pūtau ngeniwhero roto ngarahu romahā - rino-kei roto pūmua pūtoto. Ko te matua mahi o ngā pūtau toto whero kawe hāora, i te mea faufaa mo te mahi o whēkau katoa i roto i te tinana. I roto i te hanganga o enei pūtau hāngai ki te hinu wheua wheua whero. whakaongaongatia ana tēnei tukanga e erythropoietin, hua nei i roto i ngā pūtau rōrahi tākihi nui i raro i ngā āhuatanga hypoxic.

Pūnoa ariā pūtoto, me te hanganga o ngā pūtau toto whero he taea anake i roto i te aroaro o te cyanocobalamin, me waikawa folic, me te tika supply o katote rino. I roto i te erythrocytes tohanga nahanaha te tīariari e pā ana ki 4 marama. Na reira ko te whakangaromanga o ngā pūtau toto, he wahi mo ratou kinonga ko te kōateate me te pūnaha reticuloendothelial.

Eaha te auraa MCV?

MCV ngeniwhero taupū ko te taupū e faaite te uara o te rōrahi toharite o ngā pūtau toto whero. I roto i te tikanga ki te whakatū i tētahi tātaritanga tika o te mate ki te tūroro, whakahau tonu tākuta tatau toto. Deciphering MCV ta pūtau toto i roto i te huru te tinana tangata. I roto i te iwi hauora, he tamau te ōwehenga o ngā pūtau toto whero ki te rōrahi toto katoa, a reira, e kore e puta ke to ratou rahi me te maha.

I runga i te whanaketanga o mate pāwera, mumura, e taea te kitea kore o te huaora me te kohuke matū mā te haere i te toto MCV-tātari. Deciphering nga hua e whakaatu ana abnormalities, taunakitanga o taea āhua pathological.

tautuhi ana tēnei taupū e rite i roto i te tātari haumanu whānui o te toto, me te i roto i te ako motuhake.

Me pēhea te ki te tātai i te MCV

Hei tātai i te rōrahi toharite o te pūtau toto whero he tika ki te wehe i te nui o rōrahi pūtau i te katoa maha o ngā pūtau ngeniwhero toto. Ko tētahi atu tikanga mo te tātai hematocrit i runga i te tau wehenga taupū ranei ki 1 mm ³ o toto i te maha o ngā pūtau toto whero. I raro i te toharite ōwehenga hematocrit ōrau i waenganui i te rōrahi o ngā pūtau toto, me te katoa rōrahi toto.

I MCV tātari toto, wetemuna o nei e pā ana te ki te aro mātai o te rahi ngeniwhero whakaaro te ki kia iti tika i roto i te rite ki te atu tikanga tātaitanga e rua. Ko e tika ana ki te meka e ka ke te diameter o te pūtau ngeniwhero i runga i te 5% o tona rōrahi e 15% tenei. kia fakakehei ai te tika o tenei tohu ina he maha nui o ngā pūtau toto whero e kua puta ke āhua. Hei tauira, ki te whakahaere koe i te tatau toto oti, he noa uara MCV ki te kitea he manawanui i roto i rua whänui, me te microcytosis.

kia whanau te reira i roto i te ngakau e microspherocytes te tikanga uara diameter, engari i te tere i taua o te rōrahi toharite ko i te whānuitanga noa, i te mea he aha te mea e manakohia ana i nga wa katoa pani Microscopy o toto tangohia.

wae o te inenga

Hoki te wae rōrahi toharite ngeniwhero (MCV) tangohia femtolitry (fl) micrometers pūtoru (microns ^{3) ranei.}

He aha e te tātari?

Ki tenei tawhā toto tātari ngā momo o te anemia tono maimoatanga motuhake.

hua MCV i te tātari o te toto tukua ki te wehewehe:

• anemia microcytic, hē rino me katote thalassemia ka heke ariā o te mekameka polypeptide wahi o te hanganga o te pūtoto,;
• anemia normocytic normochromic ranei e whanake i roto i mate mau, ki te kore wheua wheua tuatahi, e tika ana ki te hanga iti o erythropoietin;
• anemia macrocytic ki te hē o te waikawa folic me cyanocobalamin ka nui haere te rahi ngeniwhero.

Hoki ia kāwanatanga me ona ake maimoatanga. Hoki tātaritanga He tino nui tātari toto haumanu, wetemuna MCV (te tikanga rōrahi corpuscular) taea ki a koe te whakawa i te āhua o ngā pūtau toto whero.

Ki te mea he uara tonu tenei tohu, kua karangatia e te pūtau toto whero normocytic. I hua raro MCV taupū o ngā pūtau toto i huaina microcytic, me i ngā uara teeraa ratou whakapono macrocytic.

Te whakatau maumaui o te wai-kawehiko toenga i roto i te tinana tuku toto MCV-tātari, wetemuna mahi e tohu he huringa i roto i te pauna tote. Ki te te rōrahi toharite o ngā pūtau toto whero iti iho i te noa, he reira taea ki te kōrero e pā ana ki te kore o te wai i roto i te tinana tangata. Hei tauira, i roto i te āhua hypertonic maroketanga o MCV i whakamātautau toto tuku iho. Ki te te tohu i runga i te täkupu, ka taea tatou te kōrero e pā ana ki maroketanga hypotonic.

I te tātari o MCV taea te awe e ngā āhuatanga. Whakaiti i te rōrahi ngeniwhero toharite kia meinga hemolysis tukanga aunoa ranei i roto i pūhui poisoning ārahi. toto Low MCV-tātari, wetemuna e tohu waipiro o te manawanui, me te whakamahi o te waihā mewaro rite te taonga paitini, he kore nohinohi te hoki.

Norma MCV

Tei toharite tohu rōrahi corpuscular i runga i tau o te manawanui, nana nei i homai te MCV whakamātautau toto. Norm i roto i ia rōpū pakeke ka kia ahurei, me te whakahuatia te reira i roto i femtolitrah. whakaturia Paerewa whānuitanga o ngā uara o tenei taupū, i te mea i roto i te whānuitanga o i 80 ki te 100 femtolitrov tūroro pakeke.

I roto i te nuinga o te wā he mea tino nui tuhinga whakamātautau MCV-toto. Norma te te rawa kitea i roto i whanau hou. E kore e nui te reira 140 femtolitrov. Ka rite ki tupu te tamaiti e heke nga uara noa o tenei taupū. Ko te kupu, e kia te auau mō pēpi tau-tau i roto i te whānuitanga o i 71 ki te 84 femtolitrov. Mai i te 1 tau, me te ake ki rima tau o tau hora te uara o te rōrahi toharite o ngā pūtau toto whero i 73 ki te 85 femtolitrov. Tīmata i 5 ki te 10 tau whakaaro te ki hei te hua o te tātari tonu MCV i 75 ki te 87 femtolitrov, a ki pakeketanga anake, tae tenei tohu tikanga pakeke.

Underreporting MCV

Ki te tuku iho te uara o MCV i whakamātautau toto, tohu te reira i te whanaketanga o te anemia microcytic. Whakawhanake i te reira ki te kaimahi o ngā katote rino i roto i te wē toto, te aroaro o te mate āhua ma'i me mate tuku, te whanaketanga o te pukupuku mārere, pūhui poisoning mata tango etahi rongoā, te tūkino waipiro, i roto i te thalassemia rite heke ariā o te mekameka polypeptide, wahi o te hanganga o te pūtoto.

MCV uara teeraa

uara mā'olunga o te rōrahi toharite o ngā pūtau ngeniwhero tohu te whanaketanga o te anemia macrocytic me ētahi atu tikanga pathological e kua āhuatanga e:

• hē o te huaora B ₁₂ (cyanocobalamin) i roto i te ofatiraa absorbability;
• folievodefitsitnoy anemia ki kaimahi waikawa folic;
• anemia megaloblastic tika ki ofatiraa o te DNA kōtuitanga;
• anemia whakarihariha;
• hypothyroidism, i roto i nei i reira ko te kore o te thyroid taiaki;
• mate intestinal;
• mate ate;
• mahi iti o ngā pūtau pancreatic;
• mate o te hinu wheua wheua;
• paihana rongoā paitini ranei;
• waipiro.

kia kia paku ki runga ake i noa i roto i nga wahine Tohu MCV tātari toto ina tango te whakawhānau hormonal. Ka taea e hikareti paowa meinga hoki he hua i roto i te rōrahi toharite o ngā pūtau toto whero.

Ko te ariā o MCH

Fakataha ki whakamāramatanga o MCV, hanga tātaritanga MCH-toto e taea ki te kawe i roto i te tātaritanga pārōnaki ki te whakatau i te momo o te anemia. Te auraa ra, te ahua rite te toharite o tetahi ngeniwhero rino-kei roto pūtoto pūmua. Whanganga i roto i ngā tino.

Tātaihia te uara toharite o te ihirangi pūtoto i roto i te kotahi ngeniwhero mā te wehewehe i te kukū pūtoto i te maha o ngā pūtau ngeniwhero. I roto i te rite ki te tohu tae, taea MCH-tātari tatou ki ake tika te whakatau i te taumata o te pūmua rino-kei roto i roto i ngā pūtau toto whero.

Homai te uara o tenei taupū ko hyper- anemia motuhake, hypo me normochromic. Normohromiyu taea te kitea i roto i te iwi hauora, engari i ētahi wā tahi reira hemolytic me anemia aplastic, me te tikanga e pā ana ki te mate toto whakapeka.

A, no te hypochromia he rōrahi ngeniwhero heke, ka huaina i microcytosis heke ranei i roto i te pūtoto pūmua i roto i ngā pūtau toto whero ki te rōrahi noa. huinga taea te kupu hypochromia ki erythrocytes rite te rahi iti me ki normo- me macrocytes.

puta Hyperchromicity whakakitenga ahakoa o te waiwai o pūtoto pūmua pūtau ngeniwhero me meinga anake rōrahi o ngā pūtau toto whero. Ko e tika ana ki te meka i te hua i roto i te pūtoto i runga i te täkupu whaiaroaro ko tona whātioatanga me hemolysis tenei.
