Abanye oogqirha basasebenzisa iimvavanyo ezindala ze-RAST zokuvavanya
Uvavanyo lwe-RAST luhlobo lovavanyo lwegazi olusetyenziswa ukuvavanya ukunyamezela . Ezi zivavanyo, ezisebenzisa i-radioactivity, ziye zalahlwa yicandelo loogqirha ngokuthanda iindlela ezintsha, ezichanekileyo zokuvavanya, kodwa abanye oogqirha basasebenzisa kwiimeko ezithile.
I-RAST imele "i-radioallergosorbent." Iimvavanyo ze-RAST ziyeyona ndlela ekhuselekileyo yokuvavanya ukutya kokutya, kodwa nazo zibiza kwaye azicingwa njengechanekileyo njengemingeni yokutya.
Iingcali zonyango kunye neZiko leSizwe loLwaphulo lwezilwanyana kunye nezifo ezithathelwanayo zinconywe ngo-2010 ukuba oogqirha bashintsha igazi labo lokuvavanya ukunyuka kwezinto ezibizwa ngokuba yi-enzyme-linked linked immunosorbent test, okanye i-ELISA. Olu vavanyo lwe-allergies alusebenzise i-radioactivity, kwaye lukhuphe ngaphezu kovavanyo lwe-RAST. Nangona kunjalo, i-allergenists ezimbalwa zisasebenzisa uvavanyo lwe-RAST.
Iimvavanyo zeRAST zisetyenziswa nini?
Kwixesha elidlulileyo, iimvavanyo ze-RAST zisetyenziselwa ukudibanisa neemvavanyo zesikhumba , okanye kwiimeko apho ezinye iimvavanyo zithathwa njengengozi (umz., Xa isigulane sibhekene nesifo esibi emva kokutya ukutya). Basoloko besetyenziswe ngezikhathi ezithile kwezi meko, nangona kuninzi lwa matyala oogqirha banika i-ELISA iimvavanyo esikhundleni seemvavanyo ze-RAST.
Njengovavanyo olutsha lwe-ELISA yokunyuka kokutya, uvavanyo lwe-RAST lubandakanya ukukhangela impendulo kwi-tube ye-tube yokuhlola ephethe igazi ngaphambili elibanjwe kwisigulane, kungekhona kwisigulane ngokwalo, ngoko akukho mngcipheko wokuba umonakalo wokugulisa kwisigulane nje inxalenye yokuvavanywa kwamanye amazwe.
Iimvavanyo zeengcingo kunye nemingeni yokutya ziqhuba loo mngcipheko wokusabela kakubi, yingakho kufuneka ukuba zenziwe phantsi kolawulo lwezonyango.
Iingenelelo kunye neentsilelo zeemvavanyo zeRAST
Iimvavanyo ze-RAST zibhekwa njengento engathandekiyo kunezilwanyana ezinqabileyo, nakuba zibhekwa njengento echanekileyo kwaye luncedo.
Zixabiseke ngenxa yokuba zinokunika ulwazi malunga nomgangatho wokuphendula okukhoyo kwigazi legulane, kwaye awathathi ixesha elide.
Uvavanyo lwe-RAST lungasetyenziselwa kwezinye iimeko apho iimvavanyo ezingenakukwazi ukuzenza-umzekelo, kunokwenzeka ukusebenzisa uvavanyo lwe-RAST xa umntu ovavanywayo ene-eczema enzima okanye imingxuma eqhubekayo kuwo wonke umzimba onokuyiphonsa ukuvavanya ukuvavanywa, ukushiya ukuvavanya iziphumo kumbuzo.
Akukho mvavanyo yokuhlaselwa okanye iimvavanyo ze-RAST, nangona kunjalo, zibhekwa njengezichanekileyo njengeengxaki zokutya "eziyimfama," apho ungazi nto ukutya ozidlayo. Xa kunokwenzeka, uvavanyo olufanelekileyo lwe-RAST luya kuqinisekiswa rhoqo ngesingeni sokutya. Ukongezelela, iimvavanyo ze-RAST azikho kuzo zonke izinto ezinokuthi zenzeke, ngoko ke ukuba unobungozi obungavamile, ugqirha wakho akakwazi ukuyivavanya usebenzisa uvavanyo lwe-RAST.
Yintoni enokuyilindela kwi-Test RAST
Ingxenye yakho yovavanyo lwe-RAST iya kubandakanya ukudweba kwegazi elula, enokuthi yenzeke kwiofisi yakho okanye ugqirha.
Emva kokuba unikeze isampuli yegazi lakho, ochwephesha uya kwongeza i-allergen esityhalwayo kwigazi lakho elikhatywayo kwaye ubone ukuba uninzi lwe-allergen ehlangene ne-immunoglobulin E (IgE) egazini lakho. I-IgE iyinxalenye yesistim somzimba wakho sokuzivikela esilungele ukuphendula, kwaye kukho uhlobo oluthile lwe-IgE kuyo yonke i-allergen.
Emva koko, uchwepheshe webhu uza kuhlamba igazi ukuze kuphela i-allergen kunye ne-IgE e-allergen. Ekugqibeleni, ochwephesha uza kwandisa i-serum ye-radioactive kumxube, oya kwenza ukuba uxinzelelo lwe-IgE e-allergen egazini legazi lilinganiswe.
ILizwi
Uninzi lwezilwanyana zezilwanyana zisebenzisa i-ELISA i-test ye-ELISA, kunokuba ihlolwe i-RAST, imvavanyo ye-RAST yakho . Nangona kunjalo, kwezinye iimeko-ngokomzekelo, ukuba ugqirha wakho ukholelwa ukuba wenza ezinye iintlobo zokuhlolwa kweengxaki zokungabikho kwemilingo zingase zibe yingozi kuwe-ugqirha wakho unokukhetha uvavanyo lwe-RAST kwezinye iindidi zokuvavanya.
Ukuba awuqinisekanga ukuba luphi uvavanyo lwakho ugqirha wakho oye wayala okanye ukuqiqa emva kovavanyo oluyalelwe, cela udokotela wakho malunga nalo.
