COVID-19 Antigen Rapid Test Cassettes
COVID-19 Antigen Rapid Test Cassettes
1. UKUSETYENZISWA OKUHLOSIWEYO
Ikhasethi ye-COVID-19 Antigen Rapid Test Cassette yi-lateral flow immunoassay eyenzelwe ukufunyaniswa okusemgangathweni kwee-antigens ze-SARS-CoV-2 ze-nucleocapsid kwi-nasopharyngeal swab kunye ne-oropharyngeal swab evela kubantu ekurhanelwa ukuba bane-COVID-19 ngumboneleli wabo wezempilo.
2. UKUGCINWA NOZINZI
Gcina njengoko zipakishwe kwisingxobo esitywiniweyo kwiqondo lobushushu (4-30℃ okanye 40-86℉).Ikhithi izinzile ngaphakathi komhla wokuphelelwa oshicilelwe kwilebhile.
Nje ukuba uvule isingxobo, uvavanyo kufuneka lusetyenziswe kwiyure enye.Ukuba sesichengeni ixesha elide kwindawo eshushu nefumileyo kuya kubangela ukuwohloka kwemveliso.
yena LOT kunye nomhla wokuphelelwa kwashicilelwa kwilebhile.
3. ISampuli yoQokelelo
Isampulu ye-Nasopharyngeal Swab
Faka i-minitip swab kunye ne-flexible shaft (ingcingo okanye iplastiki) ngokusebenzisa i-nostril parallel nenkalakahla (kungekhona phezulu) de kube ukuchasana kudibene okanye umgama ulingana naloo nto ukusuka endlebeni ukuya kwi-nostril yesigulane, ebonisa ukudibana ne-nasopharynx.I-Swab kufuneka ifikelele kubunzulu obulingana nomgama ukusuka kwiimpumlo ukuya ekuvulekeni ngaphandle kwendlebe.Gcoba ngobunono kwaye uqhube i-swab.Shiya i-swab kwindawo imizuzwana emininzi ukuze ufunxe iimfihlo.Susa iswab kancinane ngelixa uyijikelezisa.Iisampuli zinokuqokelelwa kumacala omabini usebenzisa i-swab efanayo, kodwa akuyimfuneko ukuqokelela imizekelo kumacala omabini ukuba i-minitip ihluthelwe ngolwelo olusuka kwingqokelela yokuqala.Ukuba i-septum etenxileyo okanye ukuvaleka kubangela ubunzima ekufumaneni lo mzekelo kwimpumlo enye, sebenzisa i-swab efanayo ukufumana isampuli kwenye impumlo.
Isampulu ye-Oropharyngeal Swab
Faka i-swab kwi-pharynx yangasemva kunye neendawo ze-tonsillar.Hlikihla i-swab phezu kweentsika zombini kunye ne-oropharynx yangasemva kwaye uphephe ukubamba ulwimi, amazinyo, kunye neentsini.
Ukulungiselela Isampulu
Emva kokuba isampuli zeSwab ziqokelelwe, i-swab inokugcinwa kwi-reagent ye-extraction enikwe nekhithi.Kananjalo inokugcinwa ngokuntywiliselwa intloko ye-swab kwityhubhu ene-2 ukuya kwi-3 mL yesisombululo sogcino lwentsholongwane (okanye isisombululo se-isotonic saline, isisombululo se-tissue culture, okanye i-phosphate buffer).
UKULUNGISWA KOMSEBENZI
1.Khulula isiciko se-reagent yokutsalwa.Yongeza yonke i-reagent ye-specimen extraction kwi-tube yokukhupha, kwaye uyibeke kwisikhululo somsebenzi.
2.Faka isampuli ye-swab kwi-tube yokukhupha equlethe i-reagent yokukhupha.Roll swab ubuncinane amaxesha ama-5 ngelixa ucinezela intloko ngezantsi kunye necala lombhobho wokukhupha.Shiya i-swab kwi-tube yokukhupha ngomzuzu omnye.
3.Susa i-swab ngelixa ucofa amacala ombhobho ukukhupha ulwelo kwi-swab.Isisombululo esithathiweyo siya kusetyenziswa njengomzekelo wovavanyo.
4.Faka i-tip ye-dropper kwi-tube yokukhupha ngokuqinileyo.
INKQUBO YOVAVANYO
1. Vumela isixhobo sovavanyo kunye neesampulu ukuba zilingane nobushushu (15-30℃ okanye 59-86℉) phambi kovavanyo.
2. Susa ikhasethi yovavanyo kwisingxobo esivaliweyo.
3. Ukubuyisela umva ityhubhu yokutsalwa komzekelo, ubambe ityhubhu yokutsalwa kwesampuli ngokuthe nkqo, tshintshela amathontsi ama-3 (malunga ne-100μL) kwiqula le-specimen (S) lekhasethi yovavanyo, emva koko uqalise isibali-xesha.Jonga umfanekiso ongezantsi.
4. Linda imigca enemibala ivele.Ukutolika iziphumo zovavanyo ngemizuzu eyi-15.Sukuzifunda iziphumo emva kwemizuzu engama-20.
UKUTOLIKWA KWEZIPHUMO
Okuhle:*Kuvela imigca emibini.Umgca omnye onemibala kufuneka ube kwindawo yokulawula (C), kwaye omnye umgca wembala ocacileyo kufuneka ube kwindawo yokuvavanya (T).Ilungile kubukho be-SARS-CoV-2 nucleocapsid antigen.Iziphumo ezilungileyo zibonisa ubukho be-antigens yentsholongwane kodwa ukulungelelaniswa kweklinikhi kunye nembali yesigulane kunye nolunye ulwazi loxilongo luyimfuneko ukufumanisa imeko yokusuleleka Iziphumo ezilungileyo azikhuphi usulelo lwebhaktheriya okanye ukusuleleka kunye nezinye iintsholongwane.I-arhente efunyenweyo ayinakuba ngunobangela oqinisekileyo wesifo.
Okubi: Umgca omnye onemibala ubonakala kwindawo yokulawula (C).Akukho mgca uvelayo kwindawo yovavanyo (T).Iziphumo ezibi ziyazicingela.Iziphumo zovavanyo ezingalunganga aziluthinteli usulelo kwaye akufuneki zisetyenziswe njengesona siseko sonyango okanye ezinye izigqibo zolawulo lwesigulane, kubandakanywa izigqibo zolawulo losulelo, ngakumbi xa kukho iimpawu zekliniki kunye neempawu ezihambelana ne-COVID-19, okanye kwabo bebekhe bagula. ukudibana nentsholongwane.Kucetyiswa ukuba ezi ziphumo ziqinisekiswe yindlela yokuvavanya i-molecular, ukuba kuyimfuneko, kulawulo lwesigulane.
Ayisebenzi: Umgca wolawulo awubonakali.Umthamo wesampulu engonelanga okanye ubuchule benkqubo obungachanekanga zezona zizathu ezinokuthi zibe kho zokungaphumeleli komgca wolawulo.Jonga inkqubo kwaye uluphinde uvavanyo usebenzisa ikhasethi entsha yovavanyo.Ukuba ingxaki iyaqhubeka, yeka ukusebenzisa iqashiso ngoko nangoko kwaye uqhagamshelane nomsasazi wakho wendawo.
