What Is COLA? Accreditation Overview & Its Benefits

What Is COLA?

The Commission on Office Laboratory Accreditation (COLA) is one of the most recognized laboratory accreditors in the United States. It’s dedicated to improving healthcare and patient care in laboratories nationwide through its accreditation and educational services. By partnering with medical laboratories, COLA aims to make the accreditation process simple and quick while meeting their needs. The certificate demonstrates the quality system of organizations, patient care, healthcare workflows, laboratory quality, and the accuracy and reliability of the results produced by the labs.

Its straightforward strategy helps clinical laboratory professionals easily meet CLIA requirements. Further, its LabUniversity® platform provides them with continuing education opportunities to improve their healthcare services and skills.

In 1993, the Health Care Financing Administration (now CMS, Centers for Medicare and Medicaid Services) granted COLA with the deeming authority for laboratory accreditation, which was later also recognized by the Joint Commission (TJC).

Now, COLA, Inc. is a physician-directed accreditation organization and sole accreditation provider whose program runs under an ISO 9001:2015-certified quality management system.

Medical labs eligible for COLA accreditation include office labs, mobile labs, community hospital labs, and other reference laboratories. However, labs whose CLIA certificate has been revoked within 24 months are not eligible to operate a COLA-accredited laboratory.

Currently, the organization is headquartered in Columbia. It’s Executive Team includes such key members as Nancy Stratton, the company’s Chief Executive Officer, Kathy Nucifora (Chief Operating Officer), David Chhieng (Chief Medical Officer), and Danielle Stroughton Duncan (Director of Education).

COLA and CLIA (Clinical Laboratory Improvement Amendments) follow the same regulatory requirements. However, there are minor differences regarding how they intersect:


  • Works at the national level.
  • Inspectors move across states for lab inspections to ensure consistent implementation of the regulation.
  • Performs correlation studies between the new and old installed instruments for performance comparison.
  • Requires that the old and new control lot numbers overlap at least five times.


  • Administered at the state level.
  • Quality of implementation differs between different states.
  • Doesn’t involve any correlation studies for instruments.
  • Requires the overlapping of old and new control lot numbers but doesn’t have any specific number limit.

Throughout this article, we will examine all of the prerequisites for COLA’s laboratory accreditation program. We’ll also review how your laboratory can earn the accreditation certificate after the complete implementation of COLA and CLIA regulations.

How Does the COLA Accreditation Process Work?

In addition to meeting CLIA and other regulatory requirements, COLA-accredited clinical labs also benefit from its educational products and services, which help companies achieve accreditation.

COLA’s accreditation approach is designed to streamline the accreditation process and collect all the required information for the improvement of the laboratory’s quality system. It’s a straightforward process where:

  • First, COLA prepares the laboratories using its educational tools before performing on-site surveys.
  • Laboratories’ standards are evaluated based on COLA criteria.
  • COLA then develops a customized accreditation approach that best fits the medical organizations applying for the accreditation.

1. Apply for Enrollment

To apply for the COLA accreditation, the first step is to:

  • Sign up with COLA
  • Set up your account
  • Provide laboratory information
  • Pay the enrollment fee

After payment, you will receive COLA’s welcome packet containing:

  • Enrollment letter
  • Laboratory Information Packet
  • COLA Accreditation Manual CD
  • Forms to perform the self-assessment
  • Three administrative forms:
  • Form VI: Laboratory Director Signature Form, which outlines COLA’s and the laboratory’s agreement.
  • Form IX: Annual Test Volume, which is used by the labs to report their annual test volume.
  • Form XI: Proficiency Test Data Release Form, which authorizes the proficiency testing provider of labs to send proficiency test results to COLA.  

You must submit all of the above forms to COLA, along with any other general laboratory information, to begin the accreditation process.

2. Self-assessment

After enrollment, labs are required to perform self-assessment to evaluate their performance before an on-site survey. All the information provided implies if the laboratory complies with each criterion mentioned in the form.

The questions in the self-assessment form outline COLA’s Criteria for Quality

Laboratory Performance, which is also used by the COLA surveyors during the on-site surveys and evaluation of laboratories.

After the submission of the self-assessment form, labs’ responses are reviewed by COLA. At this stage, any non-compliances are identified. Thereafter, COLA will inform laboratories of these non-compliance and ask labs to make improvements before the on-site survey.

3. On-site Survey

COLA surveyors visit the laboratory for on-site surveys. They will review your documentation, quality assurance, and proficiency testing activities. From the obtained information during the survey, the surveyors will also examine the lab’s process and its ability in delivering on-time, accurate, and reliable results.

At this time, laboratory staff must also guide surveyors through labs and answer all/any questions they have. All general, research, and healthcare staff must be familiar with all the policies and procedures of the lab.

4. Post-survey & Corrective Action

Lastly, the surveyors share the survey summary with the lab director and healthcare staff. They mention any additional non-compliant criteria (if any are still found), and offer further education and training guidance as necessary.

Surveyors send a data report from their on-site visits to COLA, after which COLA generates a separate report noting the lab’s accreditation status. COLA also sends a Plan of Required Improvement (PRI) to laboratories containing information on the remaining areas of non-compliance.

After identification of non-compliances, COLA helps the laboratories to take corrective actions by providing educational materials, support and advice, and hand-on consultations.

Lastly, labs are required to create and implement a corrective action plan and submit all the appropriate required documents to COLA.

5. Accreditation

After correcting all non-compliant criteria, the laboratories are provided with a COLA Accreditation Certificate. The accreditation certificate is valid for a total of two years.

During the two years, COLA continues to monitor lab performance and help labs to maintain the state licensure standards and federal regulations.
