Melemo ea tlhahiso ea rona:
Re sebelisa lisebelisoa tse tala tse khethiloeng hantle kamehla, boleng bo holimo ba likhechana tsa tšepe. 'Me nako le nako ha laboratori ea rona e hlahloba lisampole tse sa reroang ho tsoa thepa bakeng sa netefatso ea ho qetela, ka pono le ho leka metsoako ea eona ea lik'hemik'hale jj.
Ts'ebetso eohle ho kenyeletsoa ho qhibilihisa ka ontong, ho centrifugation, ho omisa, ho temperature, ho tima, ho hlahloba le ho paka jj., kaofela re laola le ho laola hantle ke lihlopha tsa rona tsa litsebi. Har'a tsena, ontong ea rona e kholo ho feta e le 'ngoe, e na le bokhoni ba 15mts, e re nolofalletsa ho hlahisa lihlahisoa tse ngata. 'Me re na le mela e tsoelang pele ea ho temperature, mela ea ho paka ea roboto e iketsang jj. Tsena tsohle li netefatsa tšebeletso e betere le boleng ho bareki ba rona ba lefats'e ka bophara.
