1) Chotsani chubu lachitsanzo ndi swab.Musanatenge chitsanzo, lembani zomwe zili patsamba laposungira chubu kapena kulumikiza chizindikiro cha bar code.
2) Chotsani chitsanzo cha swab ndikusonkhanitsira chitsanzo ndi swab pagawo lolingana molingana ndi zosiyanasampuli zofunika.
3. A) Kusonkhanitsa kwapakhosi: Choyamba, kanikizani lilime ndi lilime spatula, kenaka tambasulani mutu wa swab.Pakhosi ndikupukuta matani a pharyngeal ndi khoma lakumbuyo la pharyngeal, ndikuzungulira pang'onopang'onotengani chitsanzo chonse.
3. B) Kutolere chitsanzo cha m’mphuno: Yezerani mtunda kuchokera kunsonga kwa mphuno mpaka kumakutu ndi swab ndilembani ndi chala chanu.Ikani swab m'mphuno yamphuno molunjika kumphuno (nkhope).The swab ayeneraatalikitsidwe osachepera theka la utali wake kuchokera ku nsonga ya m'khutu mpaka kunsonga kwa mphuno.Sungani swab mu mphuno kwa 15-30masekondi.Pang'onopang'ono tembenuzani swab 3-5 ndikutulutsa swab.
4) Ikani swab mu chubu chosungirako mwamsanga mutatolera zitsanzo, thyola swab;kuviika mutu waswab mu njira yosungira, taya chogwirira cha sampuli ndikumangitsa kapu.
5) Zitsanzo zotengedwa kumene ziyenera kutumizidwa ku labotale mkati mwa maola 48.Ngati ntchito kwa tizilombo nucleickudziwa asidi, nucleic acid iyenera kuchotsedwa ndikuyeretsedwa posachedwa.Ngati kusungidwa kwa nthawi yayitali kumafunika,ziyenera kusungidwa pa -40 ~ -70 ℃ (nthawi yosungirako khola ndi zinthu ziyenera kutsimikiziridwa ndi labotale iliyonsemalinga ndi cholinga chomaliza choyesera).
6) Pofuna kuwongolera kuchuluka kwa kuzindikira ndikuwonjezera kuchuluka kwa ma virus a zitsanzo zomwe zasonkhanitsidwa, zitsanzo zapakhosindipo mphuno imatha kusonkhanitsidwa nthawi imodzi ndikuyika mu chubu limodzi lachitsanzo kuti liwunikenso.
