- The service fees are collected every 2-3 months (JAN to MAR, APR to JUN, JUL to AUG and SEP to DEC). Because the accounts are closed at the end of year, the service fees for sample analysis conducted from Sep. 1 to Dec. 31 will be charged early the next year.
- There is no prepaid plan for the service fee. Service fees will only be charged after sample analysis.
