Abanye odokotela basasebenzisa ukuhlolwa okudala kwe-RAST kokuhlolwa kokunciphisa umzimba
Uhlolo lwe-RAST luhlobo lokuhlolwa kwegazi okusetshenziselwa ukuvivinya imizimba . Lezi zivivinyo, ezisebenzisa i-radioactivity, ziye zalahlwa odokotela ukuze zithole izindlela ezintsha, ezinembile zokuhlolwa kokunciphisa umzimba, kodwa odokotela abathile basasebenzisa ngezimo ezithile.
I-RAST imele "i-radioallergosorbent." Ukuhlolwa kwe-RAST bekuye indlela ephephile kakhulu yokuhlola izidakamizwa zokudla, kodwa futhi ziyabiza futhi azibhekwa njengezinembile njengezinselelo zokudla.
Imiphakathi yezokwelapha kanye neSikhungo Sikazwelonke Sokungezwani Komzimba kanye nezifo ezithathelwanayo esinconywe ngo-2010 ukuthi odokotela bashintsha igazi labo ukuhlolwa kokuvivinya umzimba kulokho okubizwa ngokuthi i-test immunosorbent-ehlobene ne-enzyme, noma i-ELISA, ukuhlolwa. Lokhu kuhlolwa kokungezwani komzimba akusebenzi ukusebenzisa i-radioactivity, futhi kuzwela kakhulu kune-RAST test. Noma kunjalo, i-allergists embalwa isasebenzisa ukuhlolwa kwe-RAST.
Izivivinyo ze-RAST zisetshenziswa nini?
Esikhathini esedlule, izivivinyo ze-RAST zazivame ukusetshenziselwa ukuhlanganiswa nezivivinyo zesikhumba , noma ezimweni lapho ezinye izivivinyo zibhekwa njengengozi (isib., Lapho isiguli sibhekane nesisindo esinzima ngemuva kokudla ukudla). Zisetshenziselwa ngezikhathi ezithile kulezi zimo, nakuba kuningi lamacala odokotela abenza izivivinyo ze-ELISA esikhundleni sokuhlolwa kwe-RAST.
Njengesivivinyana esisha sokuhlolwa kwe-ELISA yokudla, ukuhlolwa kwe-RAST kuhilela ukufuna ukusabela ku-allergen esitokisini sokuhlola esinegazi okwakusungulwe ngaphambili esigulini, hhayi esigulini ngokwayo, ngakho-ke akukho ngozi yokuba nomthelela wokugulisa isifo esigulini njengoba ingxenye yokuvivinya umzimba.
Izivivinyo ze-Prick nezinselelo zokudla zithwala leyo nengozi yokuphendula okungalungile, yingakho kudingeke kwenziwe ngaphansi kokuqondiswa kwezokwelapha.
Izinzuzo Nezinkinga Zemizamo Ye-RAST
Izivivinyo ze-RAST zibhekwa njengokungathi zibucayi kakhulu kunezicucu zesikhumba, nakuba zibhekwa njengento enembile futhi ewusizo.
Ziyigugu ngoba zinganikeza ulwazi mayelana nezinga lokuphendula okweqile elikhona egazini likagulane, futhi azithathi isikhathi esiningi.
Izivivinyo ze-RAST nazo zingasetshenziswa kwezinye izimo lapho ukuvivinya okungahle kwenzeke khona-ngokwesibonelo, kungenzeka ukuthi usebenzise uhlolo lwe-RAST uma umuntu evivinywa ane-eczema enzima noma ama-hive aphikisayo kuwo wonke umzimba ongahle alahle ukuhlolwa okuphambene, eshiya ukuhlolwa okuphambene kubangela umbuzo.
Izivivinyo ze-RAST noma izivivinyo ze-RAST, noma kunjalo, zibhekwa njengezinembile njengezinselelo zokudla "eziyimpumputhe", lapho ungazi ukuthi yini oyidla ukudla. Uma kunokwenzeka, ukuhlolwa okuhle kwe-RAST kuzovame ukuqinisekiswa ngenselele yokudla. Ngaphezu kwalokho, izivivinyo ze-RAST azikho kuzo zonke izinhlobo ezingaba khona, ngakho-ke uma ngabe ukuhlukunyezwa okungavamile kukhishwa, udokotela wakho ngeke akwazi ukukuhlola ngokusebenzisa uhlolo lwe-RAST.
Yini Ongayilindela Evivinyweni RAST
Ingxenye yakho yohlolo lwe-RAST izobandakanya ukudweba kwegazi okulula, okungenzeka kwenzeke ehhovisi likadokotela wakho noma ebhokisatri.
Uma usuhlinzekele isampula segazi lakho, lochwepheshe uzokwengeza i-allergen ecatshangelwayo egazini lakho elikhathele bese ubona ukuthi ingakanani le-allergen ehlangene ne-immunoglobulin E (IgE) egazini lakho. I-IgE iyinxenye yesistimu yakho yokuzivikela omzimba enesizathu sokuphendula okweqile, futhi kukhona uhlobo oluhlukile lwe-IgE kuwo wonke ama-allergen.
Okulandelayo, ochwepheshe welebhu uzogeza igazi ukuze kuphela i-allergen ne-IgE ekhethekile ye-allergen. Okokugcina, lochwepheshe uzokwengeza i-serum e-radioactive ekuxubeni, okuzokwenza ukuba ukuhlushwa kwe-IgE ethize-bloodgen egazini likagulane kulinganiswe.
Izwi kusuka
Abaningi be- allergen basebenzisa ukuhlolwa kwe-ELISA okucabangelayo, kunokuba kusetshenziswe izivivinyo ze-RAST ezidala, ukuhlola igazi lakho ngenxa yemithi . Kodwa-ke, kwezinye izimo-isibonelo, uma udokotela wakho ekholelwa ukuthi enze ezinye izinhlobo zokuvivinya umzimba kungase kube yingozi kuwe-udokotela wakho angakhetha ukuhlolwa kwe-RAST ngaphezu kwezinye izinhlobo zokuhlolwa.
Uma ungaqiniseki ukuthi yikuphi okuvivinywa udokotela wakho oye wayala noma ukucabanga ngemuva kokuhlolwa kuyiwe, cela udokotela wakho ngakho.
