New City Osaki Clinic homepage > Frequently asked questions > Question 6
It takes about two weeks to activate and increase lymphocytes.
It is important that you follow the schedule of visits in order to administer cultured and activated lymphocytes while they are in good condition. If you cannot come to the clinic on the scheduled day for compelling reasons, however, we can postpone the administration for up to one week.
As soon as you know your situation, please contact the clinic and reschedule the appointment.
