The exercise took place on Wednesday, August 14 at the Western Regional Police Headquarters in Sekondi.
It lasted less than an hour, 3news.com can confirm.
The samples will be matched against the human remains found in Sekondi/Takoradi earlier this month in the search for the girls.
While three sets of human remains were found in a septic tank near the residence of the suspected kidnapper, a fourth set was found at Nkroful New Site, where Samuel Udoetuk-Willis was rearrested when he broke jail.
It is exactly a year since the first case of a missing girl was reported in Takoradi.
Ruth Quayson, Priscilla Blessing Bentum and Priscilla Koranchie were first reported missing before a fourth girl was also kidnapped.
Samuel Udoetuk-Willis has been held in police custody over the crime and he has been assisting in investigations.
