Laboratory testing in the physician's office improves efficiency and quality of patient care because test results can be available at the time the patient is seen. Laboratory technology has produced systems that are reliable, simple to use and inexpensive.
Residents should obtain the knowledge and skills required to maintain a high-quality laboratory for their patients. In addition, residents should be able to qualify to direct a laboratory in compliance with federal and state regulations.
An understanding of federal regulations such as Clinical Laboratory Improvement Amendment (CLIA-88), the role of the laboratory director and the elements of quality assurance and quality control are essential. In addition, residents should learn about the requirements of the physical plant, equipment, laboratory needs, written policies and procedures, including an understanding of the role of the Commission on Office Laboratory Accreditation (COLA), Joint Commission on Accreditation of Healthcare Organizations (JCAHO) and Occupational Safety and Health Administration (OSHA) safety requirements.
Residents should also be able to evaluate the feasibility of performing tests, considering laboratory space, office staff and financial implications. Test volumes, equipment and reagent costs, technician time, cost of quality control, testing liability and charge to the patient should also be considered.

The minimal educational experience required by CLIA is 20 hours of didactic and laboratory workshops. It is suggested that the experience be divided into approximately 15 hours of didactic training and at least five hours of laboratory skills. The 15 hours of didactic time could meet the CLIA certification for laboratory director if the following times are allocated:
Regulations: 1 hour
Physical plant: 1 hour
Testing systems and equipment: 3 hours
Quality assurance: 3 hours
Quality control: 3 hours
Laboratory personnel: 2 hours
Written policies, procedures and individual performance responsibilities: 2 hours
The guidelines can be accomplished on a longitudinal basis or through an in-depth, intense experience utilizing family practice and laboratory educators.
