Zotsatira za RAST zingakhale zovuta kutanthauzira
Chiyeso cha RAST (RAST chimaimira "test testens") imayesa mlingo wa maselo enaake omwe amapezeka m'magazi anu. Mwachidule, izo zikutanthauza kuti mayesero amachititsa chitetezo cha thupi lanu ku chitetezo chakuthupi .
Ngakhale zili choncho, madokotala ochepa akugwiritsa ntchito mayeso a magazi a RAST kuti ayang'anire matenda. M'malo mwake, akugwiritsa ntchito zomwe zimatchedwa "immunosorbent testay", kapena ELISA, mayeso a magazi, omwe ndi ovuta kwambiri ndipo safuna kugwiritsa ntchito mauthenga.
Komabe, dokotala wanu akhoza kukhala ndi zifukwa zokonda teknoloji yakale ya RAST. Ngati ndi choncho, apa pali ndondomeko yotanthauzira zotsatira zanu.
Zotsatira Zoyesedwa Zowonjezera: Zowonongeka kutanthauzira
Chitetezo chanu cha mthupi chimatulutsa zomwe zimatchedwa antibodies kuti zimenyane ndi zomwe zimawoneka ngati zoopsa, monga kachilombo kapena mabakiteriya. Mukakhala ndi zakudya zowonjezera, zimatanthawuza kuti chitetezo chanu cha mthupi chimapanga ma antibodies okonzeka kumenyana ndi zakudya zomwe mumakhala nazo. Izi ndizo zimayambitsa zowawa.
Dokotala wanu atapereka mayeso a RAST, mudzakhala ndi zitsanzo za magazi. Ma laboratory omwe amachititsa mayesowa amatha kugwiritsa ntchito zipangizo zamakono za RAST pofuna kuyang'ana ma antibodies enieni a mtundu wa IgE mumsampha wa magazi.
Komabe, izi ndi pamene zimakhala zovuta kwambiri. Mayeso a RAST angakuuzeni kuchuluka kwa wodwala wodwalayo motsutsana ndi mankhwala enaake omwe ali m'magazi anu. Komabe, sikuti onse omwe ali ndi ma antibodies omwe ali m'magazi awo amachitanso chimodzimodzi ndi kukhalapo kwa thupi lonse (mwa mankhwala, izi zimadziwika monga vivo -malo mwake, mnofu).
Mwa kuyankhula kwina, munthu amene ali ndi matenda ochepa a antibody wina m'magazi awo akhoza kukhala ndi vuto lalikulu pamene akukumana ndi allergen mu thupi. Pa mbali ya flip, munthu yemwe ali ndi kachilombo ka HIV kameneka sangachitepo kanthu, kapena pang'ono chabe, kupita ku allergen akakumana ndi moyo weniweni.
Pachifukwa chachiwiri, munthu ameneyo sakhala wotsutsana ndi chakudya, ngakhale kuyesedwa kwa magazi kunatuluka bwino. (Izi zimadziwika ngati zabodza zabodza .)
Mayeso a RAST sali ovuta kwambiri - ali ndi chiŵerengero chochepa cha zotsatira zabwino zabodza ndi chiwerengero chokwanira cha zotsatira zoipa zabodza, ngakhale izi zimasiyanasiyana ndi allergen. Komabe, anthu ambiri omwe ali ndi ma antibodies apadera m'kati mwa mayeso a RAST amakhala ndi mwayi wochepa wokhudzana ndi chakudya m'moyo weni weni, makamaka ngati zotsatira zawo zowononga khungu ndizosawonongeke, Tili ndi mbiri yakuchitira chakudya chomwecho.
Zotsatira Zanu Zowona za RAST
Zakudya zosiyana zili ndi magawo osiyana omwe amaonedwa kuti ndi "predictive" mu yesero la RAST, kutanthauza kuti angadziwe ngati mungayesedwe ndi chakudya chimenecho. Ochita kafukufuku amadziwika bwino poyerekezera zotsatira za RAST ndi zotsatira za zovuta zowonongeka kuti athandizidwe kuti apeze mayeso ochepa omwe ali ndi kachilombo ka magazi komwe anthu ambiri ali ndi vutoli.
Izi zikutanthauza kuti simungathe kufanizitsa nambalayi pa mayesero a RAST osiyana siyana - chifukwa cha chakudya chimodzi, chiwerengero chikhoza kuimira zotsatira zabwino, koma kwa ena, chiwerengerocho chimatulutsa zotsatira zoipa.
Ndibwino kudziwa kuti zikhalidwe za IgE zodziwika nthawi zambiri zimayikidwa mu ma unit of micrograms pa mamililita (μg / mL). Ena, komabe, amanenedwa pa chiwerengero cha nambala (nthawi zambiri, koma osati nthawizonse, kuyambira 0 mpaka 5 kapena 6). Kuyeza kuyesedwa, 0 nthawizonse kumasonyeza mwayi wochepa kwambiri wa chakudya chenicheni, pamene chiwerengero chapamwamba chikhoza kuwonetsa mphamvu zowopsa kwambiri ndipo zimakhala zovuta kwambiri kuti zichitike.
Zotsatira Zoyesedwa Zowonjezera: Zofunikira
N'zotheka kuti dokotala wanu agwiritse ntchito zotsatira kuchokera mu RAST yanu kuti athandize kupeza mbali zina za mankhwala anu. Mayeso a RAST angathandize kudziwa ngati mwana akuwonetsa zizindikiro zowonjezera zakudya zowonjezera.
Ngakhale kuti zakudya zina zowonjezera zakhala zodalirika, nthawi zina zimakhala zosiyana ndi msinkhu wa odwala, ndipo asayansi sanadziwe kuchuluka kwa zakudya zonse.
Kafukufuku wina pa mayesero a RAST adanena kuti ana ambiri adauzidwa kuti sangadye zakudya zomwe adatha kuzipirira panthawi ya mavuto. Ndicho chifukwa chake mayeso a RAST amaperekedwa pamodzi ndi mbiri yachipatala mosamala, kuyezetsa khungu ngati kuli kotheka ndipo, pakuyenera, mavuto a zakudya.
Mawu Ochokera
Mayesero a RAST ndi njira imodzi yokha ya kuyesa zakudya zowonjezera. Iwo angapereke zizindikiro zina zofunika kuti athandizidwe kuti mudziwe chifukwa chake muli ndi zizindikiro, koma wodwalayo angagwiritse ntchito limodzi ndi zovuta zina zolimbitsa thupi.
Monga nthawizonse, ngati muli ndi mafunso enieni okhudza kutanthauzira zotsatira za mayeso, kapena kudabwa chifukwa chake munapatsidwa mayeso a zachipatala monga gawo la chakudya cha matenda odwala matenda opatsirana pogonana, odwala kapena odwala matendawa ndi munthu wabwino kwambiri.
