Ekuhlaziyeni wegazi RDW ephakanyiswe noma sehliselwe - kusho ukuthini?

Lapho benza ukuhlolwa igazi ukuthi ihlola hhayi kuphela inani lamaseli yayo, kodwa futhi izinga labo. Izici ezifana umbala, ijamo, isayizi futhi ubaluleke sitholakele isifo futhi ngezikhathi ezithile kuphela izimpawu pathognomonic. Ngakho-ke, zegazi ucelwa ukuba ucacise assays elabhorethri futhi RDW, esimelela njengoba ukusakazwa kwamangqamuzana egazi abomvu ngosayizi.

Kuyini lokhu?

Ngesisekelo igazi lethu, ngaphezu uketshezi, namangqamuzana ezivezwa umnkantsha. Eza ezintathu izinhlobo: obomvu, omhlophe nama-platelet. Kulokhu, sinesithakazelo kwesikwenzayo amangqamuzana abomvu noma amangqamuzana abomvu egazi. Lokhu encane biconcave disc ukuma, okuyinto lenza igazi libe nombala, kanye kukhona abathwali oksijini evela emaphashini ezicutshini futhi izitho. Ngo abantu abayimiqemane, konke okufanayo ijamo, umbala kanye ivolumu. Kuyinto kusukela sibalo yokugcina incike ekusebenzeni efanele kulezi cells. Wabiza MCV futhi evamile ingahluka kancane, ibizwa ngokuthi ububanzi ukusatshalaliswa ivolumu.

Uma udokotela ongabikezela ukuthi isiguli singenakukwazi Ukushintsha ivolumu sezitokisi, ithumela ku-CBC. RDW ne umsizi azichaye. Lokhu kuyiqiniso ikakhulukazi uma Anisocytosis nasemkhakheni igazi.

Kusho ukuthini RDW e ukuhlolwa igazi? Lena kakhulu ukuhlukumeza wokusabalalisa kwamangqamuzana egazi abomvu ngosayizi.

Anisocytosis - ushintsho sokugembula ebukhulwini kwamangqamuzana egazi abomvu. Ngokuvamile kuhluka eziyisikhombisa ukuba micrometer eyisikhombisa nengxenye. Microcytes anosayizi kuze kufinyelele 6.9 micrometer, futhi macrocytes ngokulandelana micrometer eziyisishiyagalombili kuya kweziyishumi nambili. amaseli Okukhulu lwadlulela ngokusebenzisa ubukhulu capillary, njengoba zisetshenziswa ubende. Kumuntu ophile isilinganiso amangqamuzana avamile futhi ezishintshwe abomvu zokhahlamba kusuka 5: 1. Anisocytosis anaemia emtholampilo lapho kubonakala, ukuhluleka kwenhliziyo, iphika, cyanosis. Izimbangela kulesi simo kungase kube ukuntuleka kwamavithamini, ikakhulukazi B 12 futhi Ukuntuleka yensimbi, ukuphazamiseka of umnkantsha, ezifana syndrome myelodysplastic noma ukuba khona Ukudlulela ngesikhathi umdlavuza wegazi. Ukwelashwa incike imbangela kanye kuyehla ziqedwe yayo.

Injongo sokuhlaziya

Ngokuvamile RDW ekucubunguleni wegazi kunqunywa ngokuhlanganyela nezinye amamethrikhi lapho besanda kuqala ukuxilongwa. Lolu cwaningo angaqokwa njengoba kwakuhleliwe, ngesikhathi isiguli esibhedlela eziphuthumayo, ngaphambi kokuba uhlinzwe. Ngaphezu kwalokho, amaqembu athile eziguli definition RDW ukwenza njalo ukulandelela Dynamics ukwelapha izifo igazi.

Nge yalokho omuhle, udokotela kufanele akhethe isifundo eyalandela, ngoba ngaphansi kwethonya izici ezingaphandle ihlonzwe ezincane test zamanga-HIV ngoba RDW.

Kla futhi RDW

Njengomthetho, igazi kunqunywa ukuhlaziywa RDW futhi ukuthola MCV. Lokhu kusiza ukubona ngokugcwele isithombe lesi sifo futhi ukuhlukanisa omunye noma olunye uhlobo igazi microcytic. Uma Inkomba ngezansi MCV ngenxa, ngesilinganiso RDW, kungase kube uphawu lokungabi pathologies ezinzima ezifana thalassemia, ukumpontshelwa igazi, ukopha, nabanye abaningi. Ngaphezu kwalokho, ngezinye izikhathi izinqubo neoplastic angase anikeze isithombe igazi, ikakhulukazi uma isiguli ziphathwe ngamakhemikhali.

Mhlawumbe isimo esichazwe okuphambene, lapho MCV kukaKayafase esikhundleni uphawu futhi RDW zibuyele kokujwayelekile. Le nhlanganisela liphawuleka izifo zesibindi. Kodwa ngenxa yokugcina libhekene uhlobo kwamakhemikhali igazi isithombe futhi coagulation, ukuze uphethwe umehluko udokotela akunzima.

Izindlela cwaningo

Isiguli unika igazi umthambo esiswini esingenalutho, kodwa izingane ezincane nezinsana igazi ngokwanele kusuka umunwe. Ngemva lab iqede reception, ubeka amasampula endaweni Centrifuge ukuhlukanisa ingxenye ewuketshezi yegazi emangqamuzaneni. Khona-ke ubeka okuholela ezisalayo lomisile analyzer futhi idivayisi ngokwayo sinquma inani izinhlobo ezihlukene zamangqamuzana, ihlola kubo, futhi wenza umbiko. Imiphumela okukhiphayo iphrinta njengoba histogram.

Uma ukuhlaziywa inguyebo, olandelwayo uncika uphinda yayo ukuze ugweme yalokho okungelona iqiniso. Lo mthetho usebenza cishe yonke yalolu cwaningo elihlobene ne sitholakele kwegazi, njengoba ukuhamba udokotela igazi picture kunikeza isizathu sokungabaza ngokunemba esikhethiwe ukwelashwa isu futhi ubuyekeze izindlela ngoba ukulungiswa lesimo sokugembula.

amazinga evamile

Ekuhlaziyeni wegazi RDW unikezwa embundwini amaphesenti 11,5-14,5 izinguquko ejwayelekile erythrocyte ngobukhulu omdala. Ezinganeni, lokhu ipharamitha luyehluka in the uhla kusuka 11.6 kuya kumaphesenti langema-18,7. Phela, abakwazi konke ifane patsi.

Esibonisa RDW Inkomba, kumelwe kukhunjulwe ukuthi le ndlela akuxhomekile usayizi cell. Lokhu kungase kunikeze imiphumela engemihle yamanga, futhi ixhunywe nge yokuthi inani elikhulu Ushintshe abomvu egazi ashaye khona egazini. Lezi amangqamuzana abomvu egazi okubizwa ngokuthi ama macrocytes. Ngezinye izikhathi, ukuze uthathe imiphumela yokuhlaziya njengento enhle, kubalulekile hhayi kuphela ekuhambisaneni RDW, kodwa ukuhlanganisa yayo nge MCV.

ukusebenza anda

RDW e ukuhlolwa igazi kungenziwa ngcono ezimweni ezimbalwa. Imvama, kuba uphawu igazi, ngokuvamile yensimbi. Kodwa kukhona amathuba wokuthuthukisa vitamin B12 ukuntula kwegazi, ukuntula folate noma isifo sesibindi. Ngakho-ke, qiniseka ukuthi afeze ukuxilongwa umehluko, ukuqoka luhlolo eyengeziwe kanye lejulile rezultam yabo. Nquma uhlobo anaemia - umsebenzi isikhathi esiningi ngoba odokotela.

yensimbi ukuntula anaemia

Njengoba yensimbi ukuntula anaemia yisona esikhulunywa abantu abaningi e Nenkabazwe wethu, thina-ke xoxa ngawo kabanzi.

Ngo esigabeni sokuqala lesi sifo enanini lama-elementi kwakhiwa kuyinto esezingeni evamile, kodwa izinga elithwala umoya-mpilo isifinyelele umkhawulo engezansi noma lehla kakhulu. Lokhu kunikeza isizathu ukuxilonga igazi. Kodwa ekucubunguleni wegazi RDW kuyinto evamile, njengoba kusekhona anisocytosis, kanye nomnkantsha ithambo isebenza kahle.

Esigabeni esilandelayo libhekene i iconsi ngisho nakakhulu i-hemoglobin futhi abomvu cell count, kodwa manje eshintsha nezinye izinto. RDW anda ukuhlaziywa igazi, kunokwehluka inani amaseli, okuqukethwe elithwala umoya-mpilo kanye okuhlushwa yayo. I-histogram kuyoba kude kakhulu ngakwesobunxele.

Ngemva ukwelashwa, ngaphansi kokulawula igazi Ukwakheka, inombolo, isayizi shape kwamangqamuzana egazi abomvu zibuyele kokujwayelekile. Lokhu ibangelwa ethola yensimbi zinsiza.

ukwehla

Akumangalisi, kodwa uma RDW ekucubunguleni wegazi lehliselwa, kungase futhi abonisa igazi. Ngakho-ke, nakani nakwabangcwele MCV. Njengoba kungehlisa kanyekanye abonisa isifo sesibindi. Ngokuvamile kudinga ukuhlaziya ezingaphezu kweyodwa ukuqonda imbangela izinguquko ezinjalo esithombeni igazi lilonke.

Kunoma yikuphi, musa afafaze umlotha ekhanda ngaphambi kwesikhathi. Ekuhlaziyeni wegazi (RDW) kungenzeka AMANGA avunyelwe, ngoba kwenza umshini futhi kuyadingeka zokubala kabusha ngesandla. Ngaphezu kwalokho, ngeziphambeko kusukela kuyinsakavukela kungaba ngemva kokumpontshelwa igazi noma ukuhlinzwa. Khona-ke udinga ukuphinda isivivinyo kamuva.

Lapha uthola ukuhlolwa igazi. RDW - ngcono. Kusho ukuthini? Kungenzeka-ke ukuthi i-laboratory akusho ulinganise insimbi, noma uma usanda abalimele nge izinqubo ezincane kuhlinzwa, noma ubungase ukunikela.

igazi isithombe sishintsha ngokushesha ngokwanele, ngakho Awayi isidumo. Ukuhlaziywa kumele sibonise udokotela wakho ulalele izincomo zakhe ngokucophelela. Lokhu kuzosiza ukuba kugwenywe ukungaqondi kahle esikhathini esizayo. Ngaphezu kwalokho, i-laboratory ngamunye has izinkomba ekucubunguleni kwegazi - RDW, kuye ngokuthi hlobo luni imishini abawasebenzisayo. Kungenzeka Udokotela ubheke wena kuya Isikhungo sokuxilonga, imiphumela okuyinto abetsembele. Kubalulekile futhi kakhulu ngoba uyayazi imbangela.
