📊 What 'Normal Range' on a Lab Report Means

Why you can be 'abnormal' and completely fine.

How Labs Calculate Normal Ranges

  • A **reference range** is determined by testing a large group of healthy people.
  • Labs take the results from the middle 95% of that group to define what is normal.
  • This means 5% of perfectly healthy people will fall outside these borders.
  • Being outside the range does not automatically mean you are sick.
