Normal Range
Also written as: Reference Range, Reference Interval
The band of values seen in most healthy people, printed next to your result for comparison.
Where it appears in reports
Beside every numeric value on lab reports, usually in brackets.
Why it matters
It tells you whether your value sits where most healthy people's values sit. Ranges differ between labs, ages, and sexes — so always compare against the range on your own report.
High vs low
A value above the range is flagged 'H' — it may or may not be significant depending on context.
A value below the range is flagged 'L' — same rule: context decides.
Report words describe findings — they are not diagnoses. What "Normal Range" means for you depends on your symptoms, history, and other results. Always review your report with your doctor.
