How can I know what the results mean?

  • Laboratory test results are often reported with a reference interval to assist the clinician in interpreting them. These reference intervals reflect the values in the majority of healthy individuals; however, a small number of healthy people (5%) may have results that are higher or lower than those in the reference range. Therefore, laboratory results should interpreted by clinicians who can decide whether or not the results indicate a medical condition.
  • Clinicians consider personal medical history, family history, and results from physical examination when interpreting an individual patient’s laboratory test results.
