Physiological Reference Ranges
The ranges below represent standard adult physiological values. Your laboratory's printed reference range always takes precedence.
0 – 0.1 µg/L
0 – 0.1 µg/L
0 – 0.1 µg/L
What does a low result mean?
A level below 0.1 µg/L strongly suggests a viral cause, reassuringly indicating that antibiotics are likely unnecessary.
What does a high result mean?
A mild elevation points toward a bacterial response, helping the physician tailor appropriate antimicrobial therapy.

Bring these questions to your next consultation to discuss with your healthcare practitioner:
- Does this result confirm that antibiotics are not indicated for my symptoms?
- What is the most likely source of my discomfort?
- How quickly does this marker return to baseline as I recover?
