In which phase are lab tests run?

• A. Pre-Analytic Phase
• B. Analytic Phase
• C. Post Analytic Phase
• D. QC Samples

Answer: (B)

Lab tests are run during the Analytic Phase, which is the stage where the actual measurement or assay is performed using instruments, reagents, and specific methods. Everything that happens before—such as obtaining and labeling the specimen, transporting and preparing it—is the Pre-Analytic Phase. After the measurements are completed, results are reported, interpreted if needed, and stored, which is the Post-Analytic Phase. Quality control materials (QC samples) are used during the Analytic Phase to verify that the instruments and methods are functioning correctly, ensuring accurate and reliable results.
