 with various operational, personnel, facility, administration, quality and proficiency testing requirements intended to ensure the accuracy, reliability and timeliness of
patient test results. CLIA certification is also a prerequisite to be eligible to bill state and federal health care programs, as well as many commercial third-party payors, for laboratory testing services.

Our laboratories located in Menlo Park and Union City, California, are CLIA certified and must comply with all applicable CLIA regulations and standards. If a clinical
laboratory is found to be out of compliance with CLIA standards, CMS may impose sanctions; suspend, limit or revoke the laboratory’s CLIA certificate (and prohibit the owner, operator or laboratory director from owning, operating, or directing
a laboratory for two or more years following license revocation); subject the laboratory to a directed plan of correction, on-site monitoring, civil monetary penalties, civil actions for injunctive relief,
criminal penalties; or suspension or exclusion from the Medicare and Medicaid programs.

CLIA provides that a state may adopt laboratory licensure requirements and
regulations that are more stringent than those under federal law and requires compliance with such laws and regulations. A number of states have implemented their own more stringent laboratory regulatory requirements. State laws may require the
laboratory to obtain state licensure and/or laboratory personnel to meet certain qualifications and obtain professional licensure, specify certain quality control procedures or facility requirements, or prescribe record maintenance requirements.
Moreover, several states impose the same or similar state requirements on out-of-state laboratory testing specimens collected or received from, or test results reported
back to, residents within that state. Therefore, we are required to meet certain laboratory licensing requirements for those states in which we offer services or from which we accept specimens, and that have adopted laboratory regulations beyond
CLIA.

College of American Pathologists (CAP)

The College of American
Pathologists (CAP) maintains a clinical laboratory accreditation program. While not required to operate a CLIA-certified laboratory, many private insurers require CAP accreditation as a condition to contracting with clinical laboratories to cover
their tests. In addition, some countries outside the United States require CAP accreditation as a condition to permitting clinical laboratories to test samples taken from their citizens. Our two laboratories have each been accredited by CAP, which
means that our laboratories have been certified as following CAP standards and guidelines in operating the laboratory facility and in performing tests that ensure the quality of our test results. In order to maintain CAP accreditation, we are
subject to survey for compliance with CAP standards every two years.
