The bodies were found last Thursday and have now been sent to Islamabad for a DNA test.
A senior government official said the test was being done to ascertain identity of the deceased as the bodies were in bad condition and beyond recognition.
"To be honest, they are just skeletons," the official said today.
Chinese officials have been approached to get samples from relatives of the kidnapped man and woman for the DNA test, the Dawn reported.
The kidnapping of the Chinese nationals has raised concerns in Beijing over the multi-billion dollar investment in Pakistan.
The abduction forced the Chinese embassy in Islamabad to evacuate 10 of its nationals from Quetta and send them home.
