The health body recently changed the way it records the figures.
Cases identified through a positive lateral flow test – those which can deliver results within half an hour – will no longer be counted if the person then takes a PCR test, which is sent to a lab to be checked, and receives a negative result within three days.
These cases are now being removed daily.
The rate of infection in Lancashire now stands at 8,264 cases per 100,000 people, higher than the England average of 6,962.
Across the UK, the number of recorded cases increased by 12,733 over the period, to 4,490,438.
Lancashire's cases were among the 623,377 recorded across the North West, a figure which rose by 3,524 over the period.
Cumulative case counts include patients who are currently unwell, have recovered and those that have died.
