Kuyini ukuhlolwa kwegazi kwe-RDW?

Ukuhlolwa kwegazi lokusatshalaliswa kweseli elibomvu (RDW) kukala inani lokuhluka kwamaseli abomvu egazini nosayizi.

Udinga amangqamuzana abomvu egazi ukuze uthwale umoya-mpilo ususe emaphashini wakho uye kuwo wonke amalungu omzimba wakho. Noma yini engaphandle kwebanga elijwayelekile lobubanzi beseli elibomvu noma ivolumu ibonisa inkinga engaba khona ngokusebenza komzimba okungathinta ne-oxygen ukufika ezingxenyeni ezahlukahlukene zomzimba wakho.

Kodwa-ke, ngezifo ezithile, usengaba ne-RDW ejwayelekile.

Amaseli egazi abomvu ajwayelekile agcina usayizi ojwayelekile wama-micrometer ayi-6 kuye kwayi-8 ububanzi. I-RDW yakho iphakanyisiwe uma ububanzi bamasayizi bukhulu.

Lokhu kusho ukuthi uma ngokwesilinganiso ama-RBC akho emancane, kepha futhi unamaseli amancane kakhulu, i-RDW yakho izophakanyiswa. Ngokufanayo, uma ngokwesilinganiso ama-RBC wakho emakhulu, kepha futhi unamaseli amaningi amakhulu kakhulu, i-RDW yakho izophakanyiswa.

Ngalesi sizathu, i-RDW ayisetshenziswa njengepharamitha ehlukanisiwe lapho kuhunyushwa inani eliphelele legazi (CBC). Esikhundleni salokho, inikeza izincazelo zencazelo kumongo we-hemoglobin (hgb) futhi isho inani le-corpuscular (MCV).

Amanani aphezulu e-RDW angasho ukuthi unokuntuleka kwezakhi, i-anemia, noma esinye isimo esingaphansi.

Kungani kwenziwa ukuhlolwa kwe-RDW?

Ukuhlolwa kwe-RDW kusetshenziselwa ukuxilonga izinhlobo ze-anemia nezinye izimo zezokwelapha kubandakanya:

• ama-thalassemias, okuyizinkinga zegazi ezizuzwe njengefa ezingadala i-anemia enamandla
• isifo sikashukela
• Isifo senhliziyo
• isifo sesibindi
• umdlavuza

Lokhu kuhlolwa kuvame ukwenziwa njengengxenye yokubalwa kwegazi okuphelele (i-CBC).

I-CBC inquma izinhlobo nezinombolo zamaseli egazi nezinye izici ezahlukahlukene zegazi lakho, njengezilinganiso zamaplatelets, amaseli abomvu egazi namaseli amhlophe egazi.

Lezi zivivinyo zisiza ukunquma isimo sakho sempilo jikelele, futhi kwezinye izimo, ukuxilonga ukutheleleka noma ezinye izifo.

Odokotela futhi bangabheka ukuhlolwa kwe-RDW njengengxenye ye-CBC uma une:

• izimpawu zokushoda kwegazi, njengesizungu, isikhumba esiphaphathekile, nokuba ndikindiki
• ukuntuleka kwensimbi noma amavithamini
• umlando womndeni wokuphazamiseka kwegazi, njenge-sickle cell anemia
• ukulahleka kwegazi okuphawulekayo ekuhlinzweni noma ekulimaleni
• kutholakale ukuthi unesifo esithinta amangqamuzana abomvu egazi
• ukugula okungalapheki, njenge-HIV noma i-AIDS

Usilungiselela kanjani isivivinyo?

Ngaphambi kokuhlolwa kwegazi le-RDW, ungacelwa ukuthi uzile, kuya ngokuthi yikuphi okunye ukuhlolwa kwegazi okuyalelwe ngudokotela wakho. Udokotela wakho uzokunikeza imiyalo ekhethekile ngaphambi kokuhlolwa kwakho.

Ukuhlolwa kukodwa akuthathi ngaphezu kwemizuzu emi-5. Umhlinzeki wezokunakekelwa kwempilo uzothatha isampuli yegazi lakho emthanjeni aligcine kuthumbu.

Lapho ithubhu seligcwalisiwe isampula yegazi, inaliti iyasuswa, bese kufakwa ingcindezi nebhandishi elincane phezu kwendawo yokungena ukusiza ukunqanda ukopha. Ishubhu lakho legazi lizobe selithunyelwa ebhodini lokuhlola.

Uma ukuphuma kwendawo yenaliti kuqhubeka ngaphezu kwamahora ambalwa, vakashela udokotela ngokushesha.

Ihunyushwa kanjani imiphumela ye-RDW?

Ibanga elijwayelekile lobubanzi bokusatshalaliswa kwamaseli abomvu lingamaphesenti ayi-12.2 kuye kwayi-16.1 kwabesifazane abadala namaphesenti angama-11.8 kuye kwayi-14.5 kwabesilisa abadala. Uma uthola amaphuzu ngaphandle kwalolu hlu, ungaba nokushoda kwezakhi, ukutheleleka, noma esinye isifo.

Kodwa-ke, noma kumazinga ejwayelekile e-RDW, usengaba nesimo sezokwelapha.

Ukuze uthole ukuxilongwa okufanele, udokotela wakho kufanele abheke okunye ukuhlolwa kwegazi - njengokuhlolwa kwe-mean corpuscular volume (MCV), okuyingxenye ye-CBC - ukuhlanganisa imiphumela nokunikeza izincomo zokwelashwa ezinembile.

Ngaphezu kokusiza ukuqinisekisa ukuxilongwa uma kuhlangene nezinye izivivinyo, imiphumela ye-RDW ingasiza ekunqumeni uhlobo lwe-anemia ongahle ube nayo.

Imiphumela ephezulu

Uma i-RDW yakho iphezulu kakhulu, kungaba yinkomba yokushoda kwezakhi, njengokushoda kwe-iron, folate, noma uvithamini B-12.

Le miphumela ingakhombisa futhi i-macrocytic anemia, lapho umzimba wakho ungakhiqizi amaseli abomvu ejwayelekile ngokwanele, futhi amaseli owakhiqizayo makhulu kunokujwayelekile. Lokhu kungenxa yokushoda kwe-folate noma i-vitamin B-12.

Ngokwengeziwe, ungaba ne-anemia ye-microcytic, okuwukushoda kwamaseli abomvu ejwayelekile, futhi amaseli akho abomvu azoba mancane kunokujwayelekile. Ukushoda kwe-iron anemia kuyimbangela ejwayelekile ye-microcytic anemia.

Ukusiza ukuxilonga kahle lezi zimo, umhlinzeki wakho wezokunakekelwa kwempilo uzokwenza ukuhlolwa kwe-CBC bese eqhathanisa izingxenye zokuhlolwa kwe-RDW ne-MCV ukukala ivolumu yakho ebomvu yegazi.

I-MCV ephezulu ene-RDW ephezulu ivela kuma-anemias athile we-macrocytic. I-MCV ephansi ene-RDW ephezulu yenzeka kuma-anemia we-microcytic.

Imiphumela ejwayelekile

Uma uthola i-RDW ejwayelekile ene-MCV ephansi, ungahle ube ne-anemia ebangelwa yisifo esingelapheki, njengaleso esibangelwa yisifo esingapheliyo sezinso.

Uma imiphumela yakho ye-RDW ingejwayelekile kepha une-MCV ephezulu, ungahle ube ne-aplastic anemia. Lesi yisifo segazi lapho umnkantsha wakho ungakhiqizi amaseli wegazi anele, kufaka phakathi amaseli abomvu egazi.

Imiphumela ephansi

Uma i-RDW yakho incipha, azikho izinkinga ze-hematologic ezihambisana nomphumela ophansi we-RDW.

Umbono

Ukushoda kwegazi kuyisimo eselaphekayo, kepha kungadala izinkinga ezisongela impilo uma kungatholakali kahle kungelashwa kahle.

Ukuhlolwa kwegazi le-RDW kungasiza ekuqinisekiseni imiphumela yokuhlolwa kokuphazamiseka kwegazi nezinye izimo lapho kuhlanganiswa nokunye ukuhlolwa. Udokotela wakho kufanele afinyelele ekuxilongweni ngaphambi kokukunikeza izinketho zokwelashwa, noma kunjalo.

Ngokuya ngobukhulu besimo sakho, udokotela wakho angancoma ama-vitamin supplements, imithi, noma izinguquko zokudla.

Uma uqala ukuhlangabezana nezimpawu ezingajwayelekile ngemuva kokuhlolwa kwegazi lakho le-RDW noma ukuqala ukwelashwa, shayela udokotela wakho khona manjalo.
