Tilmaamaha Isticmaalka
Oggolow tijaabada, muunada, kaydinta soo saarista inay u dhigmaan heerkulka qolka (15-30℃) ka hor baaritaanka.
1. Ka saar cajaladda tijaabada ah shandad foornada xidhan oo isticmaal 15 daqiiqo gudahood. Natiijooyinka ugu fiican ayaa la heli doonaa haddii baaritaanka la sameeyo isla markiiba ka dib marka la furo boorsada qashinka.
2. Dhig tuubada soo saarista goobta shaqada Tube.
3. Geli muunada suufka tuubada soo saarida
4. Ka saar suufka markaad madaxa suufka ku tuujinayso gudaha tuubada soo saarista markaad ka saarto si aad u soo saarto dareeraha ugu badan ee suurtogalka ah u samee suufka. Tuur suufka si waafaqsan nidaamka qashin-saarka biohazard-ka.
5.Ku hafi caarada dhibcaha ee dusheeda tuubada soo saarista. Dhig cajaladda tijaabada dusha nadiif ah oo siman.
6.Ku dar 2 dhibcood oo xalka ah (qiyaastii,65μL) muunada si fiican ka dibna billow saacada. Akhri natiijada la soo bandhigay 20-30 daqiiqo gudahood, natiijadii la akhriyay 30 daqiiqo ka dib waa sax.
FARSAMADA NATIIJADA
NEGTIVE NATIIJO: |
Hal xariiq oo midab leh ayaa ka muuqda gobolka khadka kantaroolka (C). Ma jiro wax khad ah oo ka soo baxaya gobolka tijaabada (T).Natiijada taban waxay muujinaysaa in antigen-ka SARS-CoV-2 aanu ku jirin muunadda, ama uu ka hooseeyo heerka la ogaan karo ee baadhista.
TOOSANATIIJO:
Laba xariiq ayaa soo muuqda.hal xarriiq oo midab leh waa inuu ku yaal gobolka kantaroolka (C) iyo khad kale oo midab leh oo muuqda waa inuu ku yaal gobolka tijaabada (T) Natiijadu waxay muujineysaa in SARS-CoV-2 laga helay muunada.
NATIIJO AAN AHAYN:
Khadka kantaroolku wuu soo bixi waayay Dib u eeg nidaamka oo ku celi tijaabada imtixaan cusub. Haddii dhibaatadu sii socoto, jooji isticmaalka qalabka tijaabada isla markiiba oo la xidhiidh qaybiyaha xaafaddaada.
FIIRO GAAR AH:
Xoogagga midabka gobolka khadka tijaabada (T) wuu kala duwanaan doonaa iyadoo kuxiran fiirsashada SARS-CoV-2 Antigen ee ku jirta muunada. Sidaa darteed, hadh kasta oo midab ah oo ku yaal gobolka khadka tijaabada (T) waa in loo tixgeliyaa mid wanaagsan.
Kontaroolka tayada
- Xakamaynta habraaca ayaa ku jirta imtixaanka. Xariiq midab leh oo ka soo muuqda gobolka kantaroolka (C) waxaa loo tixgeliyaa kontorool habraac gudaha ah.Waxay xaqiijinaysaa xuubka ku filan.
- Heerarka xakamaynta lama bixiyo xirmadan; si kastaba ha ahaatee, waxaa lagu talinayaa in kontaroolada togan iyo kuwa taban la tijaabiyo si ay u noqdaan dhaqan shaybaar oo wanaagsan si loo xaqiijiyo nidaamka tijaabada iyo si loo xaqiijiyo waxqabadka saxda ah ee imtixaanka.
XADKAEE IMTIXAANKA
- Cassette-ka SARS-CoV-2 Antigen Degdegga ah ee Tijaabada degdegga ah waxaa loogu talagalay xirfad-yaqaannada isticmaalka ogaanshaha fayraska oo keliya. Tijaabada waa in loo adeegsadaa ogaanshaha SARS-CoV-2 Antigen ee Oropharyngeal Swab. Qiimaha tirada iyo heerka korodhka SARS- midna ma aha. U fiirsashada CoV-2 waxaa lagu go'aamin karaa tijaabadan tayada leh.
- Saxnaanta imtixaanku waxay kuxirantahay tayada muunada suufka
- Cassette-ka SARS-CoV-2 Antigen Degdegga ah ee Tijaabada ayaa kaliya tilmaami doonta joogitaanka SARS-CoV-2 ee muunada ka yimid noocyada coronavirus-ka ee SARS-CoV-2 ee la hirgelin karo iyo kuwa aan macquul ahayn.
- Sida dhammaan baaritaanada ogaanshaha, dhammaan natiijooyinka waa in lala tarjumaa macluumaadka kale ee caafimaad ee uu heli karo takhtarka.
- Natiijo taban oo laga helay xirmadan waa in ay xaqiijiso PCR. Natiijooyin taban ayaa laga yaabaa in la helo haddii xoogga saaridda SARS-CoV-2 ee ku jirta suufka aysan ku filneyn ama ay ka hooseyso heerka la ogaan karo ee baaritaanka.
- Dhiiga xad-dhaafka ah ama xababka ku jira shaybaarka suufka ayaa laga yaabaa inay farageliyaan waxqabadka waxaana laga yaabaa inay keenaan natiijo wanaagsan oo been ah.
- Natiijooyinka togan ee SARS-CoV-2 kama reebayso infekshan hoose oo leh cudur-sidaha kale. Sidaa darteed, suurtogalnimada infekshanka bakteeriyada ee aan qarsoonayn waa in la tixgeliyaa.
- Natiijooyinka taban kama saarayaan infekshanka SARS-CoV-2, gaar ahaan kuwa la xiriira fayraska. Baaritaanka daba-galka ah ee baaritaanka molecular waa in la tixgeliyo si meesha looga saaro infekshanka shakhsiyaadkan.
- Natiijooyinka wanaagsan ayaa laga yaabaa inay sabab u tahay infekshanka jira noocyada aan ahayn SARS-CoV-2 ee coronavirus, sida coronavirus HKU1, NL63, OC43, ama 229E.
- Natiijooyinka ka soo baxa baaritaanka antigen-ka waa in aan loo isticmaalin saldhigga kaliya si loo baaro ama looga saaro caabuqa SARS-CoV-2 ama in lagu wargeliyo heerka caabuqa.
- Dareeraha soo saarista ayaa awood u leh in uu dilo fayraska, laakiin ma dami karo 100% fayraska. Habka hawl-gabka fayraska waxaa loo tixraaci karaa: habka ay ku taliso WHO/CDC, ama waxaa loo maarayn karaa si waafaqsan xeerarka maxalliga ah.
