Ishubhu lokuqoqa igazi le-DNA lokubeletha okungahlanyisi lingavikela ngempumelelo amasampula egazi ngesikhathi sokuqoqwa, ukulondolozwa kanye nokuthuthwa.cfDNA.
1. Ingakwazi ukugwema ngokuphumelelayo ukungcoliswa kwe-DNA ye-genomic kusuka kumaseli ngesikhathi sokugcinwa kwegazi kanye nokuthutha.
2. Vimbela ukucekelwa phansi kwe-cfDNA yesampula.
3. Vimbela i-cfDNA ekuxhumaniseni amanye ama-biomolecules njengamaprotheni.
