Umkhumbi wokuhlanganisa = ishubhu elijwayelekile legazi → ishubhu lokudonsa kwegazi → ishubhu le-biochemical.

Qaphela: I-tube ejwayelekile yegazi kumele iqoqwe kushubhu yesibili noma kunjalo (ishubhu yegazi iyishubhu yesithathu lapho isiko legazi lithandwa kakhulu), ngaphandle kwento evamile yegazi. Onke amashubhu wokuqoqa igazi kufanele abuyiselwe emuva amahlandla ama-1 kuye kwayi-7 ngemuva kokuqoqwa kwegazi, futhi anganyakaziswa.
