Ikhithi yokuxilonga ye-Fecal Occult Blood(Uvavanyo lwe-Fluorescence Immunochromatographic Assay
Ukusetyenziswa kokuxilongwa kwi-vitro kuphela
Nceda ufunde le phakheji ngononophelo phambi kokuba uyisebenzise kwaye ulandele imiyalelo ngokungqongqo. Ukuthembeka kweziphumo zovavanyo akunakuqinisekiswa ukuba kukho naluphi na uphambuko kwimiyalelo ekwesi sithuba sephakheji.

UKUSETYENZISWA OKUJOLISWEYO
Ikhithi yokuxilonga yeGazi leMfihlo yeFecal (Uvavanyo lweMfihlo yeMfihlo yeFluorescence) ifanelekile ekufumaneni ubungakanani be-hemoglobin kwindle yabantu ngovavanyo lwe-fluorescence immunochromatographic, isebenza njengonyango lokuncedisa ukopha esiswini. Zonke iisampulu ezilungileyo maziqinisekiswe zezinye iindlela. Olu vavanyo lwenzelwe ukusetyenziswa ziingcali zempilo kuphela.

ISISHWANKATHELO
Ukopha kancinci kwesifo sendlela yokugaya ukutya kubangela i-FOB, ngoko ke ukufunyanwa kwe-FOB kubaluleke kakhulu ekuxilongweni kwesifo sendlela yokugaya ukutya, yindlela ekhoyo yokuhlola izifo zendlela yokugaya ukutya.

UMGAQO WENKQUBO
I-strip ine-anti-FOB coating antibody kwindawo yovavanyo, ebotshelelwe kwi-membrane chromatography kwangaphambili. I-lable pad igqunywe yi-fluorescence ebhalwe yi-anti-FOB antibody kwangaphambili. Xa kuvavanywa isampuli elungileyo, i-FOB kwisampuli inokuxutywa ne-anti-FOB antibody ebhalwe yi-fluorescence, kwaye yenze umxube we-immune. Njengoko umxube uvunyelwe ukuba uhambe ecaleni kwe-test strip, i-FOB conjugate complex ibanjwa yi-anti-FOB coating antibody kwi-membrane kwaye yenza i-complex. Ubunzulu be-fluorescence buhambelana kakuhle nomxholo we-FOB. I-FOB kwisampuli inokubonwa nge-fluorescence immunoassay analyzer.

Isikhongozeli sokuqokelela isampuli, isibali-xesha

IMFUNDO YOKUQOKELELA NOKUGCINA IMIZEKELO
1. Sebenzisa isitya esicocekileyo esilahlwayo ukuze uqokelele isampuli yendle entsha, kwaye uvavanywe ngoko nangoko. Ukuba awukwazi ukuvavanywa ngoko nangoko, nceda ugcine kumaqondo obushushu angama-2-8°C kangangeentsuku ezi-3 okanye ngaphantsi kwe-15°C kangangeenyanga ezi-6.
2. Khupha intonga yokuvavanya, uyifake kwisampuli yendle, uphinde isenzo izihlandlo ezi-3, thatha iindawo ezahlukeneyo zesampuli yendle ngalo lonke ixesha, uze uyibuyisele intonga yokuvavanya, uyiqinise uze uyishukumise kakuhle, Okanye usebenzisa intonga yokuvavanya ukhethe malunga ne-50mg yesampuli yendle, uze ufake ityhubhu yesampuli yendle equlethe isampuli yokuxutywa, uze uyijije kakuhle.
3.Sebenzisa isampuli yepayipi elahlwayo, thabatha isampuli yendle yomntu onesifo sorhudo, uze wongeze amathontsi amathathu (malunga ne-100µL) kwityhubhu yokuvavanya ilindle uze ushukumise kakuhle.
Amanqaku:
1. Ziphephe ii-freeze-thicken cycles.
2. Nyibilikisa iisampulu zibe kubushushu begumbi ngaphambi kokuba uzisebenzise.
INKQUBO YOVAVANYO
Nceda ufunde incwadi yemiyalelo yokusebenza kwesixhobo kunye nesihlomelo sephakheji ngaphambi kokuvavanya.
1. Beka ecaleni zonke ii-reagents kunye neesampuli ukuya kubushushu begumbi.
2.Vula i-Portable Immune Analyzer (WIZ-A101), faka igama lokugqitha le-akhawunti ngokwendlela yokusebenza kwesixhobo, uze ufake i-interface yokubona.
3.Skena ikhowudi yokuchonga ukuze uqinisekise into yovavanyo.
4.Khupha ikhadi lovavanyo kwingxowa yefoyile.
5.Faka ikhadi lovavanyo kwindawo yokubeka ikhadi, skena ikhowudi ye-QR, uze umisele into yovavanyo.
6. Susa isiciko kwityhubhu yesampulu uze ulahle amathontsi amabini okuqala esampuli exutyiweyo, yongeza amathontsi amathathu (malunga ne-100uL) isampuli exutyiweyo engaxutyiweyo ngokuthe nkqo uze kancinci ungene emthonjeni wesampulu yekhadi ene-dispette enikiweyo.
7.Cofa iqhosha elithi “uvavanyo oluqhelekileyo”, emva kwemizuzu eli-15, isixhobo siza kuzibona ngokuzenzekelayo ikhadi lovavanyo, singafunda iziphumo kwisikrini sokubonisa isixhobo, size sirekhode/siprinte iziphumo zovavanyo.
8. Jonga imiyalelo ye-Portable Immune Analyzer (WIZ-A101).
IINQOBO EZILINDELEKILEYO
I-FOB <0.2μg/mL
Kucetyiswa ukuba ilabhoratri nganye imisele uluhlu lwayo oluqhelekileyo olumele inani lezigulana zayo.
IZIPHUMO ZOVAVANYO NOKUTOLIKWA
1. I-FOB kwisampulu ingaphezulu kwe-0.2μg/mL, kwaye kufuneka ithintele utshintsho kwimeko yomzimba. Iziphumo aziqhelekanga ngokwenene kwaye kufuneka zifunyaniswe zineempawu zeklinikhi.
2. Iziphumo zale ndlela zisebenza kuphela kuluhlu lwereferensi olusekwe kule ndlela, kwaye akukho kuthelekiswa ngokuthe ngqo nezinye iindlela.
3.Ezinye izinto zinokubangela iimpazamo kwiziphumo zokufumanisa, kuquka izizathu zobugcisa, iimpazamo zokusebenza kunye nezinye izinto zesampulu.

UKUGCINWA NOKUZINZISA
1. Le khithi ihlala iinyanga ezili-18 ukususela kumhla wokwenziwa kwayo. Gcina ezi khithi zingasetyenziswanga kwi-2-30°C. SUKUZIQANDA. Musa ukuzisebenzisa emva komhla wokuphelelwa.
2. Musa ukuvula isikhwama esivaliweyo ude ulungele ukwenza uvavanyo, kwaye uvavanyo olusetyenziswa kanye lucetyiswa ukuba lusetyenziswe phantsi kweemeko ezifunekayo (ubushushu obuyi-2-35℃, umswakama oyi-40-90%) kwimizuzu engama-60 ngokukhawuleza okukhulu.
3. Isampulu yomxube isetyenziswa kwangoko emva kokuba ivuliwe.
