Physiological Reference Ranges

The ranges below represent standard adult physiological values. Your laboratory's printed reference range always takes precedence.

Adults (general)

Adult females

6 – 22 µg/dL

Adult males

6 – 22 µg/dL

Common alternative units:

µg/L(×0.1 µg/dL)

What does a low result mean?

A slightly low level can follow recent corticosteroid use (such as topical creams or nasal sprays) putting adrenals briefly at rest.

What does a high result mean?

A slightly high reading very frequently reflects morning rush, traffic, or anticipation of the blood test itself.

Questions ready for your doctor

Bring these questions to your next consultation to discuss with your healthcare practitioner:

  • Was the timing window (ideally between 7:30 and 8:30 AM) strictly observed?
  • Could morning rush or needle stress have nudged this value upward?
  • Would a late-night salivary or urinary check provide additional context?
