The IOC official said the retests were in no way connected to a German state television report about two doping labs finding hundreds of positive tests using new methods.
The IOC is eager to root out cheats long after Olympic Games by using new methods of tracing known banned substances or substances that were not known at the time.
"We are re-testing Torino Games samples as planned. This is not linked to that report," the official told Reuters.
The IOC can re-test athletes' samples from its own events up to eight years after the Games and can sanction them.
They did so with five samples from the 2004 Athens Olympics coming back positive.
According to German ARD broadcaster labs in Cologne and Moscow found traces of anabolic steroids in hundreds of urine samples using the new testing method.
It was not clear which athletes and what sports were involved and when the samples were taken.
"This case is a good example of the necessity of performing retests on Olympic doping samples. I would certainly conduct retests here," Arne Ljungqvist, head of the IOC's medical commission told ARD.
"We have the mandate for that, after all". Germany's Anti-Doping Agency (NADA) said on Tuesday none of the positive tests unearthed in tests it had authorised since late last year involved German athletes, adding, however, it would start re-testing older samples with the new methods.
"Since the end of 2012 NADA tested more than 3,500 samples using the refined methods. All samples of German athletes tested negative," it said in a statement.
"NADA also plans to re-analyse samples of selected sports and disciplines that have been stored for a longer period of time."
