Iziphumo ze-RAST zinokuba nzima ukutolika
Uvavanyo lwe- RAST (i-RAST imela "uvavanyo lwe-radioallergosorbent test") lilinganisa izinga le-anti-ge-specific IgE antibodies egazini lakho. Ngendlela elula, oko kuthetha ukuba uvavanyo lwamanyathelo omzimba wakho omzimba wokumelana nomzimba omzimba kwi- allergen ethile yokutya .
Nangona kunjalo, oogqirha abambalwa basebenzisa uvavanyo lwegazi lwe-RAST ukuze baqaphele ukunyamezela. Esikhundleni saloo nto, basebenzisa oko kubizwa ngokuba yi-enzyme-linked linked immunosorbent assay, okanye i-ELISA, uvavanyo lwegazi, oluvakalayo kwaye aludingi ukusetyenziswa kwe-radioactivity.
Nangona kunjalo, ugqirha unokufumana izizathu zokukhetha i-RAST yobudala. Ukuba kunjalo, nasi isikhokelo sokutolika iziphumo zakho zokuvavanya.
Iziphumo zovavanyo lweRAST: ezikhohlisayo ukuchazela
Isistim somzimba sakho sichaza izinto ezibizwa ngokuba ngama-antibodies ukulwa nento ebonwa njengengozi, njengegciwane okanye ibhaktheriya. Xa unesifo somzimba, kuthetha ukuba isistim somzimba sakho senza amagciwane anqwenela ukulwa nokutya onokugula. Yilokho ebangela ukuphendulwa kwemizimba.
Xa ugqirha wakho uyalela uvavanyo lwe-RAST, uya kuba nesampuli yegazi. Ibhubhoratri eyenza uvavanyo iya kusebenzisa iteknoloji ye-RAST ukujonga i-anti-ge-specific IgE antibodies kule sampuli yegazi.
Nangona kunjalo, le yilapho ithola inkohlakalo. Uvavanyo lwe-RAST lunokukuxelela ukuba uninzi lomntu olwaphikisayo olune-allergen ethile lukhoyo egazini lakho. Nangona kunjalo, akubona bonke abantu abaneengxowanxu ezifanayo kwigazi labo baya kuphendula ngendlela efana neyokoqobo ye-allergen emizimbeni yabo (ngokwemigqirha yezokwelapha, oku kwaziwa ngokuba yi- vivo- ngokwesibili, kwinyama).
Ngamanye amazwi, umntu onokuxinwa okuphantsi kwe-antibody ethile kwigazi lakhe unokufumana impendulo enzima xa edibana ne-allergen enyameni. Kwiphepha le-flip, umntu onomlinganiselo ophezulu olwaphilo lwaloo mntu uqobo akavumelekanga, okanye nje ngendlela encinane, kwi-allergen xa ehlangene nobomi bokwenene.
Kwimeko yesibini, loo mntu akayi kuhlanjululwa koko kukutya, nangona uvavanyo lwayo lwegazi luphume kakuhle. (Oku kwaziwa ngokuba yinto ekhohlakeleyo .)
Iimvavanyo ze-RAST azixhatshazi kakhulu-zinezinga eliphantsi leempembelelo ezintle kunye nenani elifanelekileyo lemiphumo engafanelekanga, nangona le nto ihluka nge-allergen. Nangona kunjalo, abantu abanomlinganiselo omncinci wee-antibodies ezithile kwi-RAST bavame ukuba nethuba elincinane lokuphendula ngokutya ebomini bobomi, ngakumbi ukuba iziphumo zabo zokuvavanya izikhumba nazo zibi, kwaye ukuba Unayo imbali yokuphendula kuloo nto.
Iimvavanyo Zakho zovavanyo lwe-RAST
Ukutya okuhlukileyo kunamanqanaba ahlukeneyo anokuthiwa "ukuqikelela" kwi-test ye-RAST, oku kuthetha ukuba banokuqikelela ukuba ngaba uya kuthatha isisombululo sokutya. Abaphandi banquma la manqanaba ngokuthelekisa iziphumo zovavanyo lweRAST kwiziphumo zemingeni yokutya engabonakaliyo ukwenzela ukuba bafumane umgangatho we-IgE ethile kwiimvavanyo zegazi apho ipesenteji ephezulu kakhulu yabantu iyancipha.
Oku kuthetha ukuba awukwazi ukuthelekisa amanani kwiimvavanyo ze-RAST ngezifo ezihlukeneyo-ngokutya okunye, inombolo ingabonisa umphumo omuhle, ngelixa enye, inamba ithetha umphumo ongalunganga.
Kukulungele ukwazi ukuba iinqununu ezithile ze-IgE zivakalayo kwiiyunithi ze-microgram nge-milliliter (μg / mL). Abanye, nangona kunjalo, bachazwa ngokulinganisa kwamanani (kaninzi, kodwa kungekho rhoqo, ukusuka ku-0 ukuya ku-5 okanye kwe-6). Kwiimvavanyo ezilinganiselwe, 0 phantse njalo ibonisa ithuba eliphantsi kakhulu lokutya okunyanzelekileyo, ngelixa amaninzi aphezulu abonisa ukuba kunokwenzeka ukuba unamandla kakhulu wokungabikho komzimba kunye nobunzima obunzima bokuphendula.
Iziphumo zoVavanyo lwe-RAST: Ukubaluleka
Kunokwenzeka ukuba ugqirha wakho asebenzise iziphumo ezivela kwi-RAST yakho ukukunceda ukucacisa iinkalo ezithile zonyango lwakho. Iimvavanyo ze-RAST zinganceda ukunquma ukuba umntwana ubonisa iimpawu zokuphelisa ukutya kokutya.
Nangona amazinga athembekileyo okubikezela asetyenziswe ukutya okunye, ngamanqanaba amaxesha ngamanye amaxesha ahluka kunye nobudala beminyaka, kwaye abaphandi abazange baqikelele amanqanaba okuqikelela kuwo onke ukutya.
Uphando olulodwa kwiimvavanyo ze-RAST lubone ukuba abantwana abaninzi babetshelwe ukuba abanakuyidla ukutya baye bakwazi ukunyamezela ngexesha locelomngeni wokutya. Kungenxa yoko iimvavanyo ze-RAST zinikezelwa kunye nembali yonyango ngokucophelela, ukuvavanywa kwesikhumba apho kunokwenzeka kwaye, xa kufanelekile, imingeni yokutya.
ILizwi
Imivavanyo ye-RAST yindlela enye yokuvavanya ukutya kokutya. Bangabonelela ngeenkcukacha ezixabisekileyo zokuncedisa ukuba kutheni unempawu, kodwa i-allergenist yakho inokuyisebenzisa ngokudibanisa nezinye izilingo zokunciphisa umzimba.
Njengokuba kunjalo, ukuba unemibuzo ethile malunga nokutolika iziphumo zakho zokuvavanya, okanye uzibuze ukuba kutheni unikwe uvavanyo oluthile lwezonyango njengengxenye yokutya kokugula kokugula, u- allergenist okanye u-immunologist ngumntu onokuzibuza.
