Abashakashatsi bo mu kigo cy’Urwibutso rwa Sloan Kettering Kanseri (MSK) basanze ibikoresho bya SARS-CoV-2 bishobora kuvumburwa mu buryo bwizewe mu macandwe y’amacandwe yegeranijwe ku kigero gisa na nasofaryngeal na oropharyngeal swabs.
Nk’uko ubushakashatsi bushya bwasohotse mu kinyamakuru cya Molecular Diagnose bwashyizwe ahagaragara na Elsevier bubitangaza, igipimo cyo gutahura amacandwe y’amacandwe gisa ku mbuga zitandukanye zipimisha, kandi iyo kibitswe mu gikapu cy’ibarafu cyangwa ku bushyuhe bw’icyumba, urugero rw’amacandwe rushobora kuguma ruhagaze neza mu gihe cy’amasaha 24 .Abantu bamwe batanga igitekerezo cyo gukoresha umunwa aho gukoresha amazuru, ariko COVID-19 ntishobora gupimwa neza.
Icyorezo kiriho cyibasiye cyane urwego rutanga, kuva ku ipamba kugeza ku bikoresho byo kurinda umuntu (PPE) bisabwa n'abakozi bo kwa muganga gukusanya neza ingero.Gukoresha amacandwe yegeranijwe wenyine afite ubushobozi bwo kugabanya imikoranire n’abakozi b’ubuvuzi no kugabanya ibikenerwa mu bikoresho byihariye byo gukusanya, nk'ipamba hamwe n’ibitangazamakuru bitwara virusi.

Ubushakashatsi bwakorewe muri MSK i New York mu gihe cyo kwibasirwa n’akarere kuva ku ya 4 Mata kugeza ku ya 11 Gicurasi 2020. Abitabiriye ubwo bushakashatsi ni abakozi 285 ba MSK bari bakeneye kwipimisha COVID-19 kandi bakagaragaza abantu banduye virusi kuko y'ibimenyetso cyangwa indwara.
Buri wese mu bitabiriye amahugurwa yatanze icyitegererezo: nasopharyngeal swab no koga mu kanwa;nasopharyngeal swab hamwe n'amacandwe y'icyitegererezo;cyangwa oropharyngeal swab hamwe n'amacandwe y'icyitegererezo.Ibyitegererezo byose bigomba gupimwa bibikwa ku bushyuhe bwicyumba hanyuma byoherezwa muri laboratoire mu masaha abiri.
Guhuza hagati yipimisha amacandwe na oropharyngeal swab byari 93%, naho sensibilité yari 96.7%.Ugereranije na nasopharyngeal swabs, guhuza ibizamini by'amacandwe byari 97.7% naho ibyiyumvo byari 94.1%.Uburyo bwiza bwo gutahura umunwa wa virusi ni 63% gusa, kandi muri rusange guhuza na nasofaryngeal swab ni 85.7% gusa.
Kugirango hamenyekane ituze, icyitegererezo cyamacandwe nicyitegererezo cya nasofaryngeal hamwe nubwinshi bwimitwaro ya virusi bibikwa muri firigo itwara abantu ku bushyuhe bwa 4 ° C cyangwa ubushyuhe bwicyumba.
Mugihe cyo gukusanya, nta tandukaniro rikomeye ryibanze rya virusi ryagaragaye mubitegererezo byose nyuma yamasaha 8 namasaha 24.Ibisubizo byagenzuwe ku mbuga ebyiri z'ubucuruzi SARS-CoV-2 PCR, kandi amasezerano rusange hagati y’ibizamini bitandukanye yarenze 90%.
Dr. Babady yagaragaje ko kwemeza uburyo bwo gukusanya uburyo bwo gukusanya ibintu bifite amahirwe menshi yo gufata ingamba zo kwipimisha kugabanya ibyago byo kwandura no gukoresha umutungo wa PPE.Yagize ati: “Uburyo rusange bw’ubuzima rusange bwo gupima, gukurikirana no gukurikirana 'kugira ngo bugenzure biterwa ahanini no kwipimisha no gusuzuma.”“Gukoresha amacandwe yegeranijwe bitanga inzira nziza yo gukusanya icyitegererezo cyiza.Amahitamo ahendutse kandi make.Ugereranije na nasofaryngeal swabs isanzwe, biroroshye rwose gucira igikombe kabiri mubyumweru.Ibi birashobora kunoza kubahiriza abarwayi no kunyurwa, cyane cyane mugupima ibizamini, bisaba guhitamo kenshi.Kubera ko twerekanye kandi ko virusi ihagaze byibuze amasaha 24 ku bushyuhe bw'icyumba, gukusanya amacandwe bifite ubushobozi bwo gukoreshwa mu rugo. ”
Janmagene SARS-CoV-2 ibikoresho byo gutahura aside nucleic birashobora kugurwa kuric843.goodao.net.
