Additional in-process sampling through solution manufacture may be done if it is decided that there's a reasonably higher possibility for introducing microbiological contamination through the producing process, such as open processes necessitating many item manipulation methods rather then entirely enclosed units, and/or prolonged production processes. Since the turnaround time for compendial sterility testing culture outcomes is prolonged (14 days for here sterility testing and 28 days for Mycoplasma
