Why reference ranges differ
Every laboratory uses its own equipment and methods, so reference ranges differ between labs. Always compare your result with the reference on your own lab report as well.
What does an abnormal value mean?
A single out-of-range value is rarely cause for concern. Results fluctuate from day to day and depend on diet, exercise, and the time of the blood draw. Read what the value means and discuss an abnormal result with your GP.

Reference ranges are the limits within which roughly 95% of healthy people's results fall. They differ by sex and sometimes by age, and every laboratory uses its own values.
My value is outside the reference range. Should I worry?
A single out-of-range value is rarely cause for concern. Results fluctuate from day to day and depend on diet, exercise, and the time of the blood draw. Always discuss an abnormal result with your GP.
Why does the reference here differ from my lab report?
Every laboratory uses its own equipment and methods, so reference ranges differ between labs. The reference on your own lab report is always the one that counts.
