“Isn’t A Number Just A Number?” Understanding Variation in Lab Results

Have you ever had patients wonder why they should not compare their True Health test results with those of another laboratory? After all, isn’t a number just a number? For a multitude of reasons, diagnostic lab results for the same test are not standard across clinical laboratories. It is not recommended that patients compare test results between laboratories.

In the diagnostic laboratory industry, there are multiple manufacturers for instruments and reagents that a laboratory can choose to use in processing tests. Depending on the manufacturer chosen for a particular test, reference ranges may vary when the validation is established.

Laboratories rely on instrumentation and reagents to ensure reproducibility and precision. As a College of American Pathologists (CAP) and Clinical Laboratory Improvement Amendments (CLIA) accredited laboratory, True Health participates in a proficiency testing program as required by law, which ensures the accuracy and validity of our testing. By choosing to use a CAP accredited clinical laboratory, clinicians can confidently trust that their patients are receiving only the highest quality results.

True Health offers clinicians a team of experts and other resources to answer questions or provide insight and clarity on understanding and interpreting our biomarkers.
