The October 21 filing says some patient records were accessed but operations were not materially disrupted.
Quest learned on October 21 that its Quanum Lab Services Manager was accessed and has not yet counted affected patients.

The lab learned of the access on October 21, has not named the data types, and found no group claiming the attack.

Quest says the Wednesday attack hit Quanum and took some protected health information; the number of patients is unstated.
Quanum Lab Services Manager was taken offline Thursday; Quest expects it back Friday and says other operations were not hit.

The October 21 Form 8-K does not say how many patients were affected or whether records were taken.

The company says certain patient records were likely accessed, but the number of patients and record types are still unknown.

Quest found the intrusion on October 21 and confirmed patient information was involved, without stating how many people.
