A dhijitari imwe-nhanho nhumbu yekubhadhara bvunzo clombocblue haizove nhaka, nekuti kunyatsojeka kunopfuura 99% kubva pazuva rekutanga rinotsaurwa kutenderera. Izvi zvinoenderana nekuvimbika kwezvidzidzo zve laboratory, uye zvakanyanya kukosha - nerubatsiro rweiyi bvunzo zvarava nyore kuona vhiki yekubata.
Muedzo mutsva wekutora nhumbu nenguva yekuzvitakura iripo kubva kuChigeblue ndiyo yekutanga uye chete yekubhadhara nhumbu yemimba, iyo ichazivisa mukadzi paakarongeka uye anomubatsira kuronga kwake chombo. Pakupedzisira, vanotsvaga vanotsvaga vakamanikidza kurota kwemukadzi - mukana wekuziva mafaira ekuvandudza nhumbu inotarisirwa uchishandisa bvunzo yemusha iri nyore. Mune ino kesi, bvunzo yekukurudzira yakachengetedza zvese zvakanakira bvunzo dzechiitiko chechizvarwa chakapfuura.
Hupfu hune hupfu hwakanyanya uye hwakareruka-kuverenga-kuverenga dijitari kuratidzwa, uye vakadzi havachafanira kufungidzira nezve mitsara inotyisa. Kana muedzo wacho uine zvakanaka, "+" uye inguva yekupa nhumbi inoratidzwa pane kuratidzwa. Kune matatu akasiyana edudziro - 1 - 2 vhiki, 2 - 3 vhiki, pamwe nemavhiki matatu uye nezvimwe.
