Vatsvagiri paChirangaridzo Sloan Kettering Cancer Center (MSK) vakawana kuti SARS-CoV-2 genetic material inogona kuwanikwa yakavimbika mumasamples emate anozviunganidza pamwero wakafanana nenasopharyngeal uye oropharyngeal swabs.
Zvinoenderana nechidzidzo chitsva muJournal of Molecular Diagnosis yakabudiswa naElsevier, chiyero chekuonekwa kwemate samples akafanana pamapuratifomu ekuyedza akasiyana, uye kana akachengetwa mubhegi rechando kana pamhepo tembiricha, sampu dzemate dzinogona kuramba dzakagadzikana kweanosvika maawa makumi maviri nemana. .Vamwe vanhu vanokurudzira kushandisa kugeza muromo pachinzvimbo chekuunganidza nasal swab, asi COVID-19 haigone kuongororwa zvakavimbika.
Denda riripo rakanganisa zvakanyanya kugovera, kubva kukotoni swabs kuenda kune zvekuzvidzivirira nazvo (PPE) inodiwa nevashandi vekurapa kuti vatore samples zvakachengeteka.Iko kushandiswa kwemate yakazviunganidza kune mukana wekudzikisa kusangana nevashandi vekurapa uye kuderedza kudiwa kwemidziyo yakakosha yekuunganidza, senge donje swabs uye hutachiona hwekufambisa media.

Chidzidzo ichi chakaitwa kuMSK muNew York panguva yepamusoro-soro yekubuda kwedunhu kubva muna Kubvumbi 4 kusvika Chivabvu 11, 2020. Vakapinda muchidzidzo vaive vashandi mazana maviri nemakumi masere nevashanu veMSK vaifanira kuongororwa COVID-19 uye kuoneswa vanhu vakatapukirwa nehutachiona nekuti. yezviratidzo kana utachiona.
Mumwe nomumwe anotora chikamu akapa muenzaniso wepairi: nasopharyngeal swab uye oral rinse;nasopharyngeal swab uye sampuli yemate;kana oropharyngeal swab uye sampu yemate.Masampuli ese anoongororwa anochengetwa pakamuri tembiricha uye anotumirwa kurabhoritari mukati memaawa maviri.
Kuenderana pakati pekuedzwa kwemate uye oropharyngeal swab yaive 93%, uye senitivity yaive 96.7%.Kuenzaniswa ne nasopharyngeal swabs, kuwirirana kwemuedzo wemate kwaiva 97.7% uye kunzwisisika kwaiva 94.1%.Iko kugona kwekuona kweoral gargle yehutachiona ndeye 63% chete, uye kuenderana kwese nenasopharyngeal swab ingori 85.7%.
Kuti uedze kugadzikana, sampu dzemate uye nasopharyngeal samples dzine huwandu hwehutachiwana hwehutachiwana dzinochengetwa mune inotonhorera inotakura pane tembiricha ye4 ° C kana tembiricha yekamuri.
Panguva yekuunganidza, hapana mutsauko wakakosha muhuwandu hwehutachiona hwakaonekwa mune chero samples mushure memaawa masere nemaawa makumi maviri nemana.Mhedzisiro iyi yakasimbiswa pamapuratifomu maviri eSARS-CoV-2 PCR, uye chibvumirano chese pakati pemapuratifomu akasiyana ebvunzo chakapfuura 90%.
Dr. Babady vakaratidza kuti kusimbiswa kwenzira dzekuzviunganidza dzemuenzaniso kune tarisiro yakakura yenzira dzakakura dzekuyedza kuderedza njodzi yehutachiona uye kushandiswa kwePPE zviwanikwa.Iye akati: "Nzira dziripo dzehutano hweveruzhinji dzeku'edza, kutevera uye kutsvaga" kuongororwa dzinoenderana zvakanyanya nekuongororwa kuongororwa uye kuongororwa."“Kushandisa mate anozviunganidza kunopa nzira iri nani yekuunganidza sampuli.Yakachipa uye isingadhure sarudzo.Kuenzaniswa neyakajairika nasopharyngeal swabs, zviri nyore kupfira kapu kaviri pasvondo.Izvi zvinogona kuvandudza kutevedza kwemurwere uye kugutsikana, kunyanya kune bvunzo dzekutarisa, dzinoda kudzokororwa sampling.Sezvo takaratidzawo kuti hutachiona hwakagadzikana kweanenge maawa makumi maviri nemana patembiricha yekamuri, kuunganidza mate kune mukana wekushandiswa kumba. ”
