Ukubaluleka Kwamakhithi Amaphakathi Ezokuthutha Ngegciwane Eqoqweni Lesampula Lamathe

Emkhakheni wokuxilongwa nokuhlaziywa kwamangqamuzana, ukuqoqwa, ukugcinwa kanye nokuthuthwa kwamasampula amathe omuntu kuyizinyathelo ezibalulekile zokuqinisekisa ukunemba nokuthembeka kwemiphumela yokuhlolwa. Kulapho amakhithi e-Viral Transport Media (VTM) edlala khona indima ebalulekile. Lawa makhithi aklanyelwe ngokukhethekile ukugcina ubuqotho be-viral nucleic acids ngesikhathi sokuthutha, okuwenza abe yithuluzi elibalulekile labachwepheshe bezempilo kanye nabacwaningi.

Umsebenzi oyinhloko weIyunithi ye-VTMukuhlinzeka ngendawo efanelekile yokulondolozwa kwe-viral nucleic acid ekhona kumasampula amathe. Lokhu kufezwa ngokusebenzisa i-transmission medium ekhethekile efakwe kukhithi. I-medium isebenza njengesivikelo esivikelayo, ivimbela ukuwohloka kwezakhi zofuzo ezibangelwa amagciwane kanye nokuqinisekisa ukuzinza kwayo ngesikhathi sokuthutha iyiswa elabhorethri ukuze iqhubeke nokuhlaziywa.

Enye yezinzuzo ezinkulu zokusebenzisa amakhithi e-VTM amandla ayo okuvikela ubuqotho be-viral nucleic acids, okuvumela ukuxilonga nokutholwa kwamangqamuzana okunembile. Amasampula alondoloziwe angenziwa ngaphansi kwamasu anhlobonhlobo okuhlaziya, okuhlanganisa ukukhuliswa kwe-PCR nokutholwa, ngaphandle kokubeka engcupheni ikhwalithi yezinto zofuzo. Lokhu kubaluleke kakhulu ekuhlolweni kwezifo ezithathelwanayo, lapho ubukhona begciwane lesandulela ngculaza kufanele buhlonzwe ngokunembile futhi bubonakale.

Ukusebenziseka kalula nokusebenziseka kalulaIkhithi ye-VTMikwenze kube yithuluzi elibalulekile kubahlinzeki bezempilo kanye nabacwaningi abathintekayo ekuqoqweni nasekuhlaziyeni isampula yamathe. Imvelo elungele ukusetshenziswa yalezi zinsiza yenza kube lula inqubo yokuqoqwa kwesampula futhi iqinisekise ukuthi amasampula alondolozwe ngendlela efanele futhi anakekelwa aze afike elabhorethri. Lokhu akugcini nje kongi isikhathi kodwa futhi kunciphisa ubungozi bokungcoliswa kwesampula noma ukucekelwa phansi.

Ngaphezu kwalokho, ukusetshenziswa kwe-VTM suite akukhawulelwe kuzilungiselelo zomtholampilo. Izikhungo zocwaningo kanye namalabhorethri okuxilonga nazo zithembele kulezi zinsiza ukuze zisekele imizamo yazo yophenyo kanye nokuxilonga. Ikhono lokuthutha amasampula amathe ngokuzethemba nangokwethembeka libalulekile ekwenzeni izifundo ze-epidemiological, izinhlelo zokugada, namaphrojekthi ocwaningo ahloselwe ukuqonda amandla okudluliselwa kokutheleleka ngegciwane.

Kafushane, ukubaluleka kwamakhithi emidiya yokuthutha ngegciwane ekuqoqweni nasekuthuthweni kwamasampula amathe omuntu akukwazi ukweqiwa. Lawa makhithi adlala indima ebalulekile ekulondolozeni ubuqotho be-viral nucleic acid, ngaleyo ndlela kube lula ukuxilongwa nokuhlaziywa kwamangqamuzana. Njengoba isidingo samathuluzi okuxilonga anokwethenjelwa siqhubeka sikhula, ama-VTM suite azohlala eyingxenye ebalulekile yokunakekelwa kwezempilo nokucwaninga, okunomthelela ekuthuthukisweni kokulawulwa kwezifo ezithathelwanayo kanye nezinhlelo zezempilo zomphakathi.
