I-viral transport media (VTM) iwumsoco osetshenziselwa ukuthwala nokugcina ukusebenza kwezibonelo (amagciwane) kuyise elabhorethri ukuze kukhonjwe futhi kuqhutshekwe nokucutshungulwa kwesampula.Imidiya yezokuthutha yamagciwane ibaluleke kakhulu njengoba ishesha kakhulu kunezinye izifo ezithathelwanayo.
Kwi-microbiology yesimanje imidiya yezokuthutha ingenye yezinto ezibaluleke kakhulu ezisetshenziswa ekuthuthweni kwezibonelo ukusuka endaweni eyodwa kuya kwenye.Ukuze kuhlaziywe ngempumelelo, Amasampula adinga ukuba sendaweni ezinzile engenalo ubungozi ezintweni eziphilayo noma endaweni ezungezile.Imithombo yezokuthutha inemisebenzi eyahlukene kuye ngohlobo lwento ephilayo esetshenziselwa yona, kanye nesikhathi okumele umzimba usichithe kuyo.I-VTM iyisivikeli esingenamsoco esilungele ukusebenzisa imidiya equkethe ama-antibiotic ahlukahlukene kanye nama-antimycotics ukuvimbela ukukhula kwamagciwane kanye nesikhunta.Lezi zingxube zingazinzisa isampula izinsuku ezingu-2 kuya kwezingu-3 ngaphansi kwezimo ezivamile ngisho nalapho isiqandisi esifanele singatholakali.Kodwa-ke, isampula akufanele sivezwe ekudluleleni kwemvelo.Imithombo yezokuthutha ibizwa kanjalo ngoba inezithako ezikhethekile ezigcina isampula yomtholampilo ukuze ithuthwe esimweni esizinzile futhi ivimbele ukuwohloka.
Njengoba kushiwo ngenhla i-VTM isetshenziselwa ukuthutha amasampula omtholampilo kanye namasampula omtholampilo wegciwane okufanele ahlolwe.Phakathi nalolu bhubhane lwe-COVID-19, i-VTM ibe ngenye yezingxube zamakhemikhali ezisetshenziswa kakhulu futhi ezifunwa kakhulu.Ama-swabs ekhala athathwe ezigulini ze-CVID-19 alondolozwa kuzixazululo ze-VTM ukuze azinze kuze kube yilapho ukuhlolwa sekuqediwe.Njengoba i-VTM ivimbela ukuwohloka okuhlobene nezinga lokushisa, ukomiswa kwesampula, futhi futhi kuthena amandla ukukhula kwamagciwane kanye nesikhunta esiza nesampula ngakho kuyisidingo esibalulekile futhi esinqunywe yi-WHO kanye ne-CDC.
