While CLSI EP28 is dominant in North and South America, the rest of the world often uses the guidelines or ISO 15189 standards. Without this document, you did not do the study

In an era of personalized medicine, we obsess over genetic variants. But the baseline—the definition of "normal" for 99% of routine testing—still comes from a well-executed reference interval study. While CLSI EP28 is dominant in North and

Aliyah recruited 120 healthy volunteers from hospital staff: non-pregnant, no chronic meds, no thyroid history. She drew their blood in the gold-top tubes at 8:00 AM sharp, spun them down, and ran them in duplicate. The data came back clean—but wrong.

In the world of laboratory medicine, a single test result is rarely a definitive diagnosis on its own. A potassium level of 4.2 mmol/L is meaningless until you know that the normal range (reference interval) is approximately 3.6 to 5.2 mmol/L. But how are those ranges established? Who decides what "normal" means?

EP28 explicitly forbids using data from hospitalized or sick patients to define a reference interval. The "normal" range derived from a hospital population will always be skewed because only sick people are in the hospital.
