Yintoni uvavanyo lwegazi lwe-RDW?

Ububanzi bokusasazwa kweseli ebomvu (i-RDW) kuvavanyo lwegazi lilinganisa inani lokwahluka kweeseli ezibomvu zegazi kubungakanani kunye nobukhulu.

Udinga iiseli ezibomvu zegazi ukuze uphathe ioksijini ukusuka kwimiphunga yakho uye kuyo yonke indawo yomzimba wakho. Nantoni na engaphandle kwoluhlu oluqhelekileyo kububanzi beeseli ezibomvu zegazi okanye ivolumu ibonisa ingxaki enokubakho ngokusebenza komzimba okunokuthi kuchaphazele ioksijini ukuya kwiindawo ezahlukeneyo zomzimba wakho.

Nangona kunjalo, ngezifo ezithile, usenokuba unayo i-RDW eqhelekileyo.

Iiseli ezibomvu eziqhelekileyo zigcina ubungakanani obuqhelekileyo beemicrometer eziyi-6 ukuya kwezi-8 ()m) ububanzi. I-RDW yakho iphakanyisiwe ukuba uluhlu lobukhulu bukhulu.

Oku kuthetha ukuba ukuba ngokomndilili ii-RBCs zakho zincinci, kodwa uneeseli ezincinci kakhulu, i-RDW yakho iya kuphakanyiswa. Ngokufanayo, ukuba ngokomndilili ii-RBCs zakho zikhulu, kodwa uneeseli ezininzi kakhulu, i-RDW yakho iya kuphakanyiswa.

Ngesi sizathu, i-RDW ayisetyenziswanga njengeparameter ekwanti xa kutolikwa inani elipheleleyo legazi (CBC). Endaweni yoko, inika intsingiselo yentsingiselo kwimeko ye-hemoglobin (hgb) kunye nexabiso le-corpuscular value (MCV).

Amaxabiso aphezulu e-RDW anokuthetha ukuba unentsilelo yesondlo, i-anemia, okanye enye imeko engaphantsi.

Kutheni le nto kwenziwa uvavanyo lwe-RDW?

Uvavanyo lwe-RDW lusetyenziselwa ukunceda ekuchongeni iintlobo ze-anemia kunye nezinye iimeko zonyango kubandakanya:

• thalassemias, ezinelifa lokuphazamiseka kwegazi kunokubangela i-anemia kakhulu
• iswekile yemellitus
• isifo sentliziyo
• isifo sesibindi
• umhlaza

Olu vavanyo lwenziwa rhoqo njengenxalenye yokubala okupheleleyo kwegazi (CBC).

I-CBC ibeka iintlobo kunye nenani leeseli zegazi kunye nezinye izinto ezahlukeneyo zegazi, ezinje ngemilinganiselo yeeplatelets, iiseli ezibomvu zegazi kunye neeseli ezimhlophe zegazi.

Ezi mvavanyo zinceda ukumisela imeko yakho yezempilo, kwaye kwezinye iimeko, ukufumanisa isifo okanye ezinye izifo.

Oogqirha banokujonga kuvavanyo lwe-RDW njengenxalenye ye-CBC ukuba:

• Iimpawu zokungabikho kwegazi, ezinje ngesiyezi, ulusu olukhanyayo kunye nobundindisholo
• i-iron okanye i-vitamin
• Imbali yosapho yokuphazamiseka kwegazi, njenge-sickle cell anemia
• ukulahleka kwegazi okubonakalayo kotyando okanye umothuko
• kwafunyaniswa ukuba unesifo esichaphazela iiseli ezibomvu zegazi
• isifo esinganyangekiyo, njenge-HIV okanye i-AIDS

Ulungiselela njani uvavanyo?

Phambi kovavanyo lwegazi lwe-RDW, unokucelwa ukuba uzilile, kuxhomekeke koluphi uvavanyo lwegazi oluyalelwe ngugqirha. Ugqirha wakho uya kukunika nayiphi na imiyalelo ekhethekileyo ngaphambi kovavanyo lwakho.

Uvavanyo ngokwalo aluthathi ngaphezulu kwemizuzu emi-5. Umboneleli wezempilo uyakuthatha isampulu yegazi lakho emthanjeni aze aligcine kumbhobho.

Nje ukuba ityhubhu igcwalise isampuli yegazi, inaliti iyasuswa, kwaye uxinzelelo kunye nebhandeji encinci ifakwa ngaphezulu kwendawo yokungena ukunceda ukunqanda ukopha. Umbhobho wakho wegazi emva koko uya kuthunyelwa elebhu ukuvavanywa.

Ukuba ukopha kwindawo yenaliti kuyaqhubeka ngaphezulu kweeyure ezininzi, tyelela ugqirha kwangoko.

Zichazwa njani iziphumo ze-RDW?

Uluhlu oluqhelekileyo lobubanzi beeseli ezibomvu zii-12.2 ukuya kwi-16.1 yepesenti kubafazi abadala kunye ne-11.8 ukuya kwi-14.5 yeepesenti kumadoda amadala. Ukuba unamanqaku ngaphandle kolu luhlu, unokuba nokusilela kwezondlo, usulelo, okanye esinye isifo.

Nangona kunjalo, kwinqanaba le-RDW eliqhelekileyo, usenokuba nemeko yonyango.

Ukufumana uxilongo olufanelekileyo, ugqirha wakho kufuneka ajonge ezinye iimvavanyo zegazi- ezinje ngovavanyo lwevolumu yecopuscular (MCV), ekwayinxalenye yeCBC- ukudibanisa iziphumo kunye nokubonelela ngonyango oluchanekileyo.

Ukongeza ekuncedeni ukuqinisekisa ukuxilongwa xa kudityaniswe nezinye iimvavanyo, iziphumo ze-RDW zinokukunceda ukumisela uhlobo lwe-anemia onokuba unayo.

Iziphumo eziphezulu

Ukuba i-RDW yakho iphezulu kakhulu, inokuba luphawu lokunqongophala kwezondlo, njengokunqongophala kwe-iron, folate, okanye i-vitamin B-12.

Ezi ziphumo zingabonisa i-macrocytic anemia, xa umzimba wakho ungazivelisi ngokwaneleyo iiseli ezibomvu zegazi, kwaye iiseli ezizivelisayo zinkulu kunesiqhelo. Oku kunokubangelwa kukusilela kwe-folate okanye i-vitamin B-12.

Ukongeza, unokuba ne-microcytic anemia, ukusilela kweeseli ezibomvu zegazi eziqhelekileyo, kwaye iiseli zakho ezibomvu zegazi ziya kuba zincinci kuneqhelekileyo. Ukunqongophala kwe-iron anemia ngoyena nobangela we-microcytic anemia.

Ukunceda ukufumanisa kakuhle le meko, umboneleli wakho wezempilo uya kwenza uvavanyo lwe-CBC kwaye uthelekise i-RDW kunye ne-MCV yovavanyo lokulinganisa umlinganiso wevolumu ebomvu.

I-MCV ephezulu ene-RDW ephezulu yenzeka kwezinye ii-macrocytic anemias. I-MCV ephantsi ene-RDW ephezulu yenzeka kwii-microcytic anemias.

Iziphumo eziqhelekileyo

Ukuba ufumana i-RDW eqhelekileyo ene-MCV ephantsi, unokuba ne-anemia ebangelwa sisifo esinganyangekiyo, esifana nesibangelwa sisifo sezintso esinganyangekiyo.

Ukuba iziphumo zakho ze-RDW ziqhelekile kodwa une-MCV ephezulu, unokuba ne-aplastic anemia. Esi sisifo segazi apho umongo wakho wethambo awuvelisi iiseli ezaneleyo zegazi, kubandakanya neeseli ezibomvu zegazi.

Iziphumo eziphantsi

Ukuba i-RDW yakho iyancipha, akukho ziingxaki ze-hematologic ezinxulumene nesiphumo esiphantsi se-RDW.

Imbonakalo

I-Anemia yimeko enokunyangeka, kodwa inokubangela iingxaki ezisongela ubomi ukuba ayifumaniswanga kakuhle kwaye inyangwa.

Uvavanyo lwegazi lwe-RDW lunokunceda ekuqinisekiseni iziphumo zovavanyo lokuphazamiseka kwegazi kunye nezinye iimeko xa zidityaniswe nolunye uvavanyo. Ugqirha wakho kufuneka afumane ukuxilongwa ngaphambi kokuba akubonise ngeendlela zonyango, nangona kunjalo.

Kuxhomekeka kubuzaza bemeko yakho, ugqirha wakho unokucebisa ngokuncedisa iivithamini, amayeza, okanye utshintsho kwindlela otya ngayo.

Ukuba uqala ukufumana naziphi na iimpawu ezingaqhelekanga emva kovavanyo lwegazi lwe-RDW okanye unyango lokuqala, tsalela ugqirha kwangoko.
