Bus. & Prof. Code, § 1301

(a) The annual renewal fee for a clinical laboratory license or registration set under this chapter shall be paid during the 30-day period before the expiration date of the license or registration. If the license or registration is not renewed before the expiration date, the licensee or registrant, as a condition precedent to renewal, shall pay a delinquency fee equal to 25 percent of the annual renewal fee for up to 60 days after the expiration date, in addition to the annual renewal fee in effect on the last preceding regular renewal date. Failure to pay the annual renewal fee in advance during the time the license or registration remains in force shall, ipso facto, work a forfeiture of the license or registration after a period of 60 days from the expiration date of the license or registration.

(b) (1) The department shall give written notice to all persons licensed pursuant to Section 1260, 1260.1, 1261, 1261.5, 1262, 1264, or 1270 30 days in advance of the regular renewal date that a renewal fee has not been paid. In addition, the department shall give written notice to licensed clinical laboratory bioanalysts or doctoral degree specialists and clinical laboratory scientists or limited clinical laboratory scientists by registered or certified mail 90 days in advance of the expiration of the fifth year that a renewal fee has not been paid and if not paid before the expiration of the fifth year of delinquency the licensee may be subject to reexamination.

(2) If the renewal fee is not paid for five or more years, the department may require an examination before reinstating the license, except that no examination shall be required as a condition for reinstatement if the original license was issued without an examination. No examination shall be required for reinstatement if the license was forfeited solely by reason of nonpayment of the renewal fee if the nonpayment was for less than five years.

(3) If the license is not renewed within 60 days after its expiration, the licensee, as a condition precedent to renewal, shall pay the delinquency fee identified in subdivision (k) of Section 1300, in addition to the renewal fee in effect on the last preceding regular renewal date. Payment of the delinquency fee will not be necessary if within 60 days of the license expiration date the licensee files with the department an application for inactive status.
