Kab mob sib kis yog ib hom kab mob uas tshwm sim los ntawm ntau yam kab mob uas kis tau ntawm tib neeg, tsiaj txhu thiab tsiaj txhu, lossis ntawm tib neeg thiab tsiaj txhu. Feem ntau tshwm sim los ntawm cov kab mob parasites, kab mob, kab mob thiab lwm yam kab mob, cov kab mob sib kis pathogendetection txoj kev muaj ntau, nrog rau kev sim tsiaj, cais tus kab mob, ELISA, PCR, immunotomography, cov kev kuaj mob no kuj yog qhov tseeb, tab sis vim xav tau tsiaj txhu, khoom siv, los yog lub sij hawm ntev dua, los yog xav tau kev tshaj lij thiab kev tshaj lij clinical daim ntawv thov.
Raws li cov tshuaj tiv thaiv cov tshuaj tiv thaiv antigen, tsiaj ntawv kuaj daim ntawv tau tsim, uas yog yooj yim, ceev thiab yooj yim nyeem, thiab tsim nyog rau kev kho mob. Cov ntawv xeem siv hauv kev kho mob yog ua raws li kev siv tshuab colloidal kub.
Colloid kub kuaj daim ntawv kuaj mob yog tsim los ntawm colloidal kub immunotomography technology, uas yog ib tug ceev thiab yooj yim immunological kuaj tshuab tsim los ntawm lub hauv paus ntawm immunofiltration technology nyob rau hauv thaum ntxov 1990s. Colloidgold yog ib qho me me ntawm cov khoom kub uas tsim los ntawm chloroquinic acid nyob rau hauv qhov kev txiav txim ntawm kev txo cov neeg ua haujlwm. Cov tshuaj zoo zoo colloidal kub tuaj yeem pom liab, qhov loj me kuj tseem sib xws. Colloidgold tuaj yeem khi ruaj khov rau cov molecules cov protein (xws li immunoglobulin) nyob rau hauv alkaline tej yam kev mob, uas ua rau tsim cov colloidal kub-labeled antibodies.
Daim ntawv sim rau nitric cellulose membrane raws li tus neeg nqa khoom, kev siv cov microporous membrane capillary nkaus, drip- ntxiv cov kua ntawm ib kawg ntawm daim nyias nyias bar maj mam seepage mus rau lwm qhov kawg, los ntawm antigen antibody khi, thiab siv cov colloidal kub los nthuav tawm xim (liab) cov tshuaj tiv thaiv, nrhiav kom tau antigen / antibody. Colloid kub suav nrog cov txheej txheem sandwich, txoj kev tsis ncaj ncees thiab txoj cai sib tw, uas feem ntau siv rau hauv kev sib piv hauv kev kho mob rau cov txheej txheem sandwich.
