Kwangexesha elide, ukufumanisa ukuba kukho naziphi izifo zesifo sofuba emzimbeni womntwana, ukusetyenziswa kweMantoux kusetyenziswa. Kodwa namhlanje le ndlela ithathelwe indawo yi-quantiferon test. Le ndlela yendlela yokuphanda yendalo yonke, engafanelekanga kuphela kwizigulana ezincinci. Kwakhona kubalulekile kubantu abadala. Kwaye xa kuthelekiswa nokuphendula kweMantou kunamathuba amaninzi.
Kutheni i-quantiferon yokuvavanya isifo sofuba ixhaphake ngakumbi kuneMantoux?
Ingozi enkulu kuMantoux kukuba le ndlela iyanqabile kwizilwanyana zokuhlaselwa isifo sofuba. Ngenxa yoko, impendulo kaninzi inokunika umphumo ontle. Ukuba ukholelwa amanani, ukusuka kuma-50 kuya kuma-70 ekhulwini kuwo onke amavanyo okuvavanya ayithembekile.
Yingakho esikhundleni seMantoux namhlanje ngokuya kwenza uvavanyo lwe quantiferon. Kuqhutywa ngokubhekiselele kwikhokhnoloji yanamhlanje, evumela ukuphepha ukufumana iziphumo ezingamanga.
Ukongeza, i-Mantoux kunye nezinye izinto - i-Diaskintest - zininzi zokuchasene. Akunakwenzeka ukusetyenziswa kwezi ndlela zokuphanda xa:
- ukunyamezela komntu ngamnye kwi-tuberculin;
- zifo;
- ubukho bezilwanyana ezinobungozi kunye nezifo ezingapheliyo;
- izikhumba;
- ukugqithisa kweemeko ezichasayo.
Iimpawu zokuhlolwa kwe quantiferon
Uvavanyo olunomlinganiselo lubucayi kakhulu kwaye luchanekile. Isekelwe ekufunyaneni kwigazi lomguli wezinto ezikhethekileyo ezingabonakala kuphela kwi-mycobacteria. I-Interferon IFN-y - into efanayo-ikhutshwa ngamathambo e-T.
Isiphumo sophando kwizigulane ngokupheleleyo, olusuleleke kwi-agent ekhuselekileyo yesifo sofuba okanye isifo sokugonywa nge-BCG siya kuba yinto embi.
Ukuba uvavanyo lwe-quantiferon luvavanyo lwama-homo, luya kubonisa umphumo omuhle, ngoko umntu uphethwe ngokuchanekileyo. Ukwesaba, xa ufumene impendulo efanelekileyo, kanye kanye akufuneki. Ukuba khona kwimizimba ye- pathogen yesifo sofuba akubonakali nesifo. Kungenzeka ukuba umntu umane nje ungumthwali wesifo. Ukuchonga indlela ekuhlakuleleni ngayo ukuveliswa kwezilwanyana, iimvavanyo zesikhumba zendabuko ziya kunceda.
Uvavanyo lwe quantiferon lwenzelwe:
- ukufumanisa ukusuleleka kwesifo sofuba;
- uphando lwabafuduki;
- ukuxilongwa ngokwahlukileyo kwezifo ezinokubangelwa yi-mycobacterium isifo sofuba.
Okokuqala, uvavanyo luqhutyelwa kwizigulane ezisengozini:
- kutshanje bedibene nabantu abanesifo;
- ngubani owenziwe ukufakelwa kwemiphunga;
- ukuxhatshazwa kwimizimba yamaphaphu;
- Abane-HIV;
- unyango lwe-immunosuppressive;
- ubandezeleka ngesifo sikashukela, i-lymphomas, i-leukemia, ukungaphumeleli kwezintso okanye izifo ezihlukeneyo;
- ephethe ubunzima obunzima bomzimba.
Iinzuzo ze-quantiferon test
Iziphumo ezinokwethenjelwayo eziphezulu neziphumo eziphezulu zokuhlolwa kwe-quantiferon aziyiyo inzuzo enkulu. Ngokungafani neesampuli ezibonisa ukufakwa kwe-tuberculin, lo vavanyo lwenziwa "kwi-vitro". Oko kukuthi, konke okufunekayo isigulane kukunikela ngegazi kwaye ulinde umphumo. Ngethuba emva kweMantoux kunye neDaaskintest, iindawo zokuqhawula kufuneka zihlolwe ngenyameko kwaye zijongwe.
Ukongezelela, uvavanyo lwe quantiferon alukho ukuphikiswa, akukho ukukhawulelwa, akukho mpendulo embi. Enyanisweni, olu phofu luvavanyo oluqhelekileyo lwegazi. Kumele unikezwe kwisisu esingenalutho ubuncinane kwiiyure ezisibhozo emva kokutya kokugqibela.
