Kwiminyaka yakutshanje, umgangatho nokhuseleko lweti luye lwatsala ingqalelo engakumbi. Iintsalela zezibulali-zinambuzane ezidlula umgangatho ziyenzeka ngamanye amaxesha, kwaye iti ethunyelwa kwi-EU isoloko ixelelwa ukuba idlula umgangatho.
Izibulali-zinambuzane zisetyenziselwa ukuthintela izinambuzane nezifo ngexesha lokutyala iti. Ngokusetyenziswa kakhulu kwezibulali-zinambuzane, iziphumo ezimbi zeentsalela zezibulali-zinambuzane ezigqithisileyo, ezingafanelekanga okanye ezisetyenziswa kakubi kwimpilo yabantu, okusingqongileyo kunye norhwebo lwangaphandle ziya zibonakala ngakumbi.
Okwangoku, iindlela zokufumanisa iintsalela zezibulali-zinambuzane kwiti ziquka ikakhulu i-liquid phase, i-gas phase, kunye ne-ultra-high performance liquid chromatography-tandem mass spectrometry.
Nangona ezi ndlela zinobukrelekrele bokubona izinto kwaye zichanekile, kunzima ukuzenza zidume kakhulu kumanqanaba asezantsi ngokusebenzisa izixhobo ezinkulu ze-chromatographic, nto leyo engafanelekanga ekuvavanyeni izinto ezinkulu.
Indlela yokuthintela i-enzyme esetyenziselwa ukuvavanya ngokukhawuleza iintsalela zezibulali-zinambuzane kwindawo ethile isetyenziselwa kakhulu ukufumanisa iintsalela zezibulali-zinambuzane ze-organophosphorus kunye ne-carbamate, eziphazanyiswa kakhulu yi-matrix kwaye zinezinga eliphezulu le-false positive.
Ikhadi lokufumanisa igolide le-colloidal likaKwinbon lisebenzisa umgaqo we-immunochromatography yokuthintela ukhuphiswano.
Iintsalela zamayeza kwisampuli ziyakhutshwa kwaye zidityaniswe ne-antibody ethile ene-colloidal gold-labeled ukuthintela indibaniselwano ye-antibody kunye ne-antigen kumgca wovavanyo (umgca we-T) kumcu wovavanyo, nto leyo ebangela utshintsho kumbala womgca wovavanyo.
Iintsalela zezibulali-zinambuzane ezikwiisampulu zimiselwa ngokwemigangatho ngokuthelekisa ubunzulu bombala womgca wokuchonga kunye nomgca wolawulo (umgca C) ngokuhlolwa ngokubonakalayo okanye ukutolikwa kwesixhobo.
Isixhobo sokuhlaziya ukhuseleko lokutya esiphathwayo sisixhobo esikrelekrele esisekelwe kubuchule bokulinganisa, ulawulo kunye nobuchwepheshe benkqubo efakiweyo.
Ibonakala ngokulula kokusebenza, uvakalelo oluphezulu lokubhaqwa, isantya esiphezulu kunye nozinzo oluhle, ukufanisa umgca wobhaqo olukhawulezayo oluhambelanayo, kunokunceda abasebenzisi abasentsimini ukuba babone ngokukhawuleza nangokuchanekileyo iintsalela zezibulali-zinambuzane kwiti.
