Physiological Reference Ranges
The ranges below represent standard adult physiological values. Your laboratory's printed reference range always takes precedence.
0 – 7 pg/mL
0 – 7 pg/mL
0 – 7 pg/mL
What does a low result mean?
A level below 7 pg/mL represents the standard, unstrained baseline of healthy immune homeostasis.
What does a high result mean?
A modest rise is common after intense athletic exercise, minor colds, or resolving seasonal illnesses.
Questions ready for your doctor
Bring these questions to your next consultation to discuss with your healthcare practitioner:
- Does this cytokine reading correlate consistently with my CRP level?
- Could recent workouts or a seasonal cold account for this variation?
- Is routine follow-up after symptom recovery adequate?
Do you have a full blood test report?
