Introduction Laboratory testing – integral part of patient care
Medical assistant must know Common laboratory equipment Safety in the laboratory Steps to prevent accidents CLIA ’88 – impact on laboratory setting Quality assurance Quality control procedures Required record-keeping
7
Role of Laboratory Testing in Patient Care
Analysis of blood, urine, and other body fluids Regular monitoring to identify diseases or other problems Confirm initial diagnosis Determine and monitor dosage of a medication
8
Role of Laboratory Testing (cont.)
Kinds of laboratories Reference laboratory Owned and operated by an organization outside the practice Have technological resources beyond the POL POL Quicker turnaround Eliminates need for patient travel to other test location Some managed care companies require their subscribers to use a specific reference laboratory.
9
Role of Laboratory Testing (cont.)
Purpose of POL Accurate and timely processing of routine tests Reporting test results to physician Tests Chemical analysis Hematologic tests Microbiologic tests Urinalysis
10
Super! Apply Your Knowledge
Compare a reference laboratory and the POL. ANSWER: A reference laboratory is lab facility usually run by an organization separate from the practice. It has technologies beyond the POL. Patients have to travel to this facility. A POL provides quicker turnaround on results but is limited in the testing that can be performed. Patients are able to have testing done during an appointment without leaving the office. Super!
11
Medical Assistant’s Role
Processing tests done in POL Preparing the patient Collecting the sample Completing the test Reporting the results Communicating information about the test
12
Medical Assistant’s Role (cont.)
Additional responsibilities Understand regulations Accident prevention Waste disposal Housekeeping and maintenance Quality assurance and control Record-keeping Inventory and order equipment and supplies Use reference materials Screen and follow-up results
13
Apply Your Knowledge Very Good!
What are the duties of a medical assistant related to testing done in the POL? ANSWER: The medical assistant duties may include preparing the patient, collecting the sample, running the test, reporting the results, and, once the physician has reviewed the results, communicating the results to the patient. Very Good!

47
Apply Your Knowledge Bravo!
Mr. Jones called for his laboratory results but the physician has not reviewed the results. What should the medical assistant do? ANSWER: The medical assistant should tell Mr. Jones that the physician has to review the results before releasing them to the patient. She should also tell Mr. Jones that she or the physician will call with the results once they are reviewed. When she reviews Mr. Jones’ laboratory results, she notes that his glucose is elevated. What should the medical assistant do? ANSWER: She should identify the test result that is out-of-range by circling or underlining it based on office policy.
