Abaphenyi baseMemorial Sloan Kettering Cancer Center (MSK) bathole ukuthi izakhi zofuzo ze-SARS-CoV-2 zingatholwa ngokuthembekile kumasampula amathe aziqoqile ngenani elifana ne-nasopharyngeal kanye ne-oropharyngeal swabs.
Ngokocwaningo olusha olukuyi-Journal of Molecular Diagnosis eshicilelwe ngu-Elsevier, izinga lokutholwa kwamasampula amathe liyafana kumapulatifomu okuhlola ahlukene, futhi lapho egcinwe esikhwameni seqhwa noma ekamelweni lokushisa, amasampula amathe angahlala ezinzile kuze kube amahora angu-24. .Abanye abantu baphakamisa ukuthi kusetshenziswe i-mouthwash esikhundleni sokuqoqwa kwe-nasal swab, kodwa i-COVID-19 ayikwazi ukutholakala ngokuthembekile.
Ubhubhane olukhona manje seluthinte kakhulu uchungechunge lokuhlinzekwa kwempahla, kusuka ku-cotton swabs kuya kumishini yokuzivikela yomuntu siqu (PPE) edingwa ngabasebenzi bezokwelapha ukuqoqa amasampula ngokuphepha.Ukusetshenziswa kwamathe aziqoqile kunamandla okunciphisa ukuthintana nabasebenzi bezokwelapha futhi kunciphise isidingo semishini ekhethekile yokuqoqa, njengama-swabs kakotini kanye nemidiya yokuthutha igciwane.

Ucwaningo lwenziwa e-MSK eNew York ngesikhathi kuqubuka udlame lwesifunda kusukela ngo-Ephreli 4 kuya kuMeyi 11, 2020. Abahlanganyeli bocwaningo babengabasebenzi abangama-285 be-MSK ababedinga ukuhlolelwa i-COVID-19 futhi bavezwe kubantu abangenwe yileli gciwane ngoba. izimpawu noma izifo.
Umhlanganyeli ngamunye unikeze isampula ebhanqiwe: i-nasopharyngeal swab kanye nokuhlanza ngomlomo;i-nasopharyngeal swab kanye nesampula yamathe;noma i-oropharyngeal swab kanye nesampula yamathe.Wonke amasampula okufanele ahlolwe agcinwa ekamelweni lokushisa futhi athunyelwe elabhorethri kungakapheli amahora amabili.
Ukungaguquguquki phakathi kokuhlolwa kwamathe kanye ne-oropharyngeal swab kwaba ngu-93%, kanti ukuzwela kwaba ngu-96.7%.Uma kuqhathaniswa nama-nasopharyngeal swabs, ukuhambisana kokuhlolwa kwamathe kwaba ngu-97.7% kanti ukuzwela kwaba ngu-94.1%.Ukuthola ukusebenza kahle kwe-oral gargle yegciwane kungamaphesenti angama-63 kuphela, futhi ukuvumelana okuphelele ne-nasopharyngeal swab kungu-85.7 kuphela%.
Ukuze kuhlolwe ukuzinza, amasampula amathe namasampula e-nasopharyngeal anohlu lwemithwalo yegciwane agcinwa endaweni epholile yokuthutha endaweni yokushisa engu-4 ° C noma ekamelweni lokushisa.
Ngesikhathi sokuqoqwa, awukho umehluko obalulekile ekugxilweni kwegciwane kunoma yimaphi amasampula ngemva kwamahora angu-8 namahora angu-24.Le miphumela yaqinisekiswa ezinkundleni ezimbili zezohwebo ze-SARS-CoV-2 PCR, futhi isivumelwano sisonke phakathi kwezinkundla zokuhlola ezihlukene seqe ama-90%.
UDkt. Babady waveza ukuthi ukuqinisekiswa kwezindlela zokuziqoqa isampula kunethuba elibanzi lamasu okuhlola abanzi ukuze kuncishiswe ingozi yokutheleleka kanye nokusetshenziswa kwezinsiza ze-PPE.Uthe: "Izindlela zamanje zezempilo zomphakathi 'zokuhlola, ukulandelela kanye nokulandela umkhondo' ukuze zibhekwe zincike kakhulu ekuhloleni ukuxilongwa nokubhekwa."“Ukusetshenziswa kwamathe aziqoqele wona kunikeza indlela engcono yokuqoqwa kwamasampula asebenzayo.Inketho eshibhile futhi engangeneleli.Uma kuqhathaniswa ne-nasopharyngeal swabs evamile, kulula ukukhafula inkomishi kabili ngesonto.Lokhu kungathuthukisa ukuthobela kwesiguli kanye nokwaneliseka, ikakhulukazi ukuhlolwa kokuqapha, okudinga ukusampula njalo.Njengoba siphinde sakhombisa ukuthi leli gciwane lizinzile okungenani amahora angama-24 ekamelweni lokushisa, ukuqoqwa kwamathe kunamandla okusetshenziswa ekhaya.”
I-Janmagene SARS-CoV-2 ikhithi yokuthola i-nucleic acid ingathengwa kuyoc843.goodao.net.
