Abaphandi kwiZiko loMhlaza we-Memorial Sloan Kettering Cancer Centre (MSK) bafumanise ukuba imathiriyeli yemfuzo ye-SARS-CoV-2 inokubonwa ngokuthembekileyo kwiisampulu zamathe eziqokelele ngokwazo ngesantya esifana ne-nasopharyngeal kunye ne-oropharyngeal swabs.
Ngokutsho kophononongo olutsha kwiJournal ye-Molecular Diagnosis epapashwe ngu-Elsevier, izinga lokufumanisa iisampulu ze-saliva lifana kwiiplatifti ezahlukeneyo zokuvavanya, kwaye xa zigcinwe kwisikhwama seqhwa okanye kwiqondo lokushisa, iisampuli zamathe zinokuhlala zizinzile ukuya kwiiyure ze-24. .Abanye abantu bacebisa ukusebenzisa i-mouthwash endaweni yokuqokelelwa kwe-nasal swab, kodwa i-COVID-19 ayinakufunyanwa ngokuthembekileyo.
Ubhubhani wangoku uchaphazele kanobom ikhonkco lokubonelela, ukusuka kwi-cotton swabs ukuya kwisixhobo sokuzikhusela (PPE) esifunwa ngabasebenzi bezonyango ukuqokelela ngokukhuselekileyo iisampulu.Ukusetyenziswa kwe-saliva eqokelelweyo inamandla okunciphisa ukudibanisa nabasebenzi bezonyango kunye nokunciphisa imfuno yezixhobo ezikhethekileyo zokuqokelela, ezifana ne-cotton swabs kunye neendaba zokuthutha intsholongwane.

Uphononongo lwenziwe kwi-MSK eNew York ngexesha lokuqhambuka kwengingqi ukusuka nge-4 ka-Epreli ukuya kwi-11 kaMeyi, 2020. Abathathi-nxaxheba kuphononongo yayingabasebenzi abangama-285 be-MSK ababedinga ukuvavanyelwa i-COVID-19 kwaye bavezwe kubantu abosulelwe yintsholongwane ngenxa yokuba. iimpawu okanye usulelo.
Umthathi-nxaxheba ngamnye unikeze isampuli edibeneyo: i-nasopharyngeal swab kunye ne-rinse yomlomo;i-nasopharyngeal swab kunye nesampuli yamathe;okanye i-oropharyngeal swab kunye nesampuli yamathe.Zonke iisampulu eziza kuvavanywa zigcinwa kubushushu begumbi kwaye zithunyelwe elebhu kwiiyure ezimbini.
Ukuhambelana phakathi kovavanyo lwe-saliva kunye ne-oropharyngeal swab yi-93%, kwaye uvakalelo lwaluyi-96.7%.Xa kuthelekiswa ne-nasopharyngeal swabs, ukuhambelana kovavanyo lwamathe kwaba yi-97.7% kunye novakalelo lwe-94.1%.Ukufumanisa ukusebenza kakuhle kwe-oral gargle ye-virus kuphela yi-63%, kwaye ukuhambelana ngokubanzi kunye ne-nasopharyngeal swab kuphela yi-85.7%.
Ukuze uvavanye ukuzinza, iisampuli ze-saliva kunye neesampuli ze-nasopharyngeal ezinoluhlu lwemithwalo yentsholongwane zigcinwa kwindawo epholileyo yokuthutha kwiqondo lokushisa le-4 ° C okanye ukushisa kwegumbi.
Ngexesha lokuqokelela, akukho ntlukwano ebalulekileyo ekugxininiseni intsholongwane efunyenwe kuyo nayiphi na iisampulu emva kweeyure ze-8 kunye neeyure ezingama-24.Ezi ziphumo ziye zaqinisekiswa kumaqonga eentengiso amabini e-SARS-CoV-2 PCR, kwaye isivumelwano xa sisonke phakathi kwamaqonga ovavanyo ahlukeneyo sigqithile kuma-90%.
UGqr. Babady wachaza ukuba ukuqinisekiswa kweendlela zokuziqokelela iisampulu kunamathuba abanzi ovavanyo olubanzi lwezicwangciso zokunciphisa umngcipheko wosulelo kunye nokusetyenziswa kwezixhobo zePPE.Uthe: "Iindlela zempilo yoluntu zangoku 'zokuvavanya, ukulandelela kunye nokulandela umkhondo' ukuze kubekwe iliso kuxhomekeke kakhulu kuvavanyo lokuxilongwa kunye nokubek'esweni.“Ukusetyenziswa kwamathe aziqokelele wona kubonelela ngendlela engcono yokuqokelela isampulu esebenzayo.Inketho engabizi kakhulu kunye nencinci.Xa kuthelekiswa ne-nasopharyngeal swabs eqhelekileyo, ngokuqinisekileyo kulula ukutshica ikomityi kabini ngeveki.Oku kunokuphucula ukuthotyelwa kwesigulane kunye nokwaneliseka, ngakumbi kwiimvavanyo zokubeka iliso, ezifuna isampuli rhoqo.Kuba sikwabonisile ukuba intsholongwane izinzile ubuncinci iiyure ezingama-24 kwiqondo lobushushu begumbi, ingqokelela yamathe inamandla okusetyenziswa ekhaya. ”
