Ofufuza ku Memorial Sloan Kettering Cancer Center (MSK) adapeza kuti ma genetic a SARS-CoV-2 amatha kuzindikirika bwino m'masampu a malovu odzisonkhanitsa okha pamlingo wofanana ndi swabs za nasopharyngeal ndi oropharyngeal.
Malinga ndi kafukufuku watsopano mu Journal of Molecular Diagnosis lofalitsidwa ndi Elsevier, kuchuluka kwa matepi amadzimadzi kumakhala kofanana pamapulatifomu osiyanasiyana oyesera, ndipo akasungidwa mu thumba la ayezi kapena kutentha kwa firiji, zitsanzo za malovu zimatha kukhala zokhazikika mpaka maola 24. .Anthu ena amati agwiritse ntchito kutsuka pakamwa m'malo motolera mphuno, koma COVID-19 sangadziwike modalirika.
Mliri wapano wakhudza kwambiri njira zogulitsira, kuyambira thonje la thonje kupita ku zida zodzitetezera (PPE) zofunidwa ndi ogwira ntchito zachipatala kuti atole zitsanzo mosamala.Kugwiritsa ntchito malovu odzisonkhanitsa okha kumatha kuchepetsa kukhudzana ndi ogwira ntchito zachipatala ndikuchepetsa kufunikira kwa zida zapadera zosonkhanitsira, monga thonje swabs ndi ma virus zoyendera media.

Kafukufukuyu adachitika ku MSK ku New York panthawi yomwe chipwirikiti chinkachitika kuyambira pa Epulo 4 mpaka Meyi 11, 2020. Ochita nawo kafukufukuyu anali antchito 285 a MSK omwe amayenera kuyezetsa COVID-19 ndikuwonetseredwa kwa omwe ali ndi kachilomboka chifukwa. za zizindikiro kapena matenda.
Wophunzira aliyense anapereka chitsanzo chophatikizira: swab ya nasopharyngeal ndi kutsuka pakamwa;swab ya nasopharyngeal ndi chitsanzo cha malovu;kapena oropharyngeal swab ndi sampu ya malovu.Zitsanzo zonse zoyesedwa zimasungidwa kutentha kwa chipinda ndikutumizidwa ku labotale mkati mwa maola awiri.
Kusagwirizana pakati pa mayeso a malovu ndi swab ya oropharyngeal kunali 93%, ndipo kumva kunali 96.7%.Poyerekeza ndi swabs za nasopharyngeal, kusagwirizana kwa mayeso a malovu kunali 97.7% ndipo kukhudzidwa kunali 94.1%.Kuzindikira bwino kwa gargle pakamwa pa virus ndi 63% yokha, ndipo kusasinthika konse ndi swab ya nasopharyngeal ndi 85.7% yokha.
Pofuna kuyesa kukhazikika, zitsanzo za malovu ndi zitsanzo za nasopharyngeal zokhala ndi ma virus angapo zimasungidwa mu chozizira choyendera kutentha kwa 4 ° C kapena kutentha kwachipinda.
Pa nthawi yosonkhanitsa, palibe kusiyana kwakukulu kwa ndende ya kachilombo komwe kunapezeka mu zitsanzo zilizonse pambuyo pa maola 8 ndi maola 24.Zotsatirazi zidatsimikiziridwa pamapulatifomu awiri amalonda a SARS-CoV-2 PCR, ndipo mgwirizano wonse pakati pa nsanja zosiyanasiyana zoyeserera udaposa 90%.
Dr. Babady adanenanso kuti kutsimikizika kwa njira zodzitolera zitsanzo kumakhala ndi chiyembekezo chachikulu cha njira zambiri zoyesera zochepetsera chiopsezo cha matenda ndi kugwiritsa ntchito zinthu za PPE.Anati: "Njira zomwe zilipo panopa zachipatala 'zoyesa, kutsata ndi kufufuza' kuti zitheke zimadalira kwambiri kuyezetsa matenda ndi kuwunika."“Kugwiritsa ntchito malovu odzisonkhanitsa tokha kumapereka njira yabwinoko yopezera zitsanzo zabwino.Njira yotsika mtengo komanso yosasokoneza.Poyerekeza ndi swabs wamba wa nasopharyngeal, ndizosavuta kulavulira kapu kawiri pa sabata.Izi zitha kupititsa patsogolo kumvera ndi kukhutira kwa odwala, makamaka pakuwunika kowunika, komwe kumafunikira kutsanzira pafupipafupi.Popeza tidawonetsanso kuti kachilomboka kamakhazikika kwa maola 24 kutentha kwachipinda, kusonkhanitsa malovu kumatha kugwiritsidwa ntchito kunyumba. ”
