Why can someone be told their labs are “normal” while their body still feels like it is running on fumes?
In this episode, Noah and Eloise take a deep dive into the My Adrenal Life article “Understanding Lab Reference Ranges in Adrenal Insufficiency.” Together, they unpack one of the most frustrating experiences in the adrenal insufficiency community: being told test results are “in range” while symptoms remain severe, persistent, and life-disrupting.
This conversation explores a critical truth about adrenal testing: reference ranges are statistical tools, not guarantees of functional safety. For people living with primary adrenal insufficiency (Addison’s disease), secondary adrenal insufficiency, tertiary adrenal insufficiency, or steroid-induced adrenal insufficiency, a number can technically fall inside the lab’s normal range and still be too low to provide meaningful reserve for daily life, illness, injury, or stress.
Noah and Eloise explain why a morning cortisol result that appears “normal” on paper may still fall into a clinical gray zone. The episode breaks down the difference between having enough cortisol to simply remain upright at rest and having enough reserve to handle real-world demands such as infection, emotional stress, surgery, or even standing up and moving through the day.
The discussion also dives into ACTH, the pituitary hormone that signals the adrenal glands to produce cortisol. One of the most important points in the episode is that ACTH cannot be interpreted in isolation. A cortisol result and an ACTH result may each look technically “normal” on their own, but when placed together, they can reveal a serious mismatch that points toward secondary adrenal insufficiency rather than health.
Noah and Eloise also examine the role of the ACTH stimulation test, which is often used to assess how well the adrenal glands respond under stress. The episode explains why this test remains valuable, but also why interpretation is more nuanced than many patients realize. Older and newer lab assays can lead to different cutoff expectations, and a detectable cortisol response does not always mean a sufficient one.
Another important theme is the role of DHEA-S as a possible clue in long-standing adrenal or pituitary dysfunction, especially when cortisol levels appear borderline. The conversation also tackles the common misunderstanding around aldosterone and renin, explaining why normal sodium, potassium, or aldosterone-related markers do not rule out adrenal insufficiency, particularly in secondary AI, where aldosterone may remain preserved.
Most importantly, this episode validates the lived experience of people who know something is wrong even when the lab report does not flag it clearly. A blood draw is a snapshot. Adrenal function is dynamic. Many patients experience the real cost of low reserve in motion, under stress, or across the rhythms of daily life – not while sitting still for a single lab test.
At its core, this conversation is about context. A result may be technically “in range” and still not be enough for a body trying to live, recover, regulate blood pressure, manage inflammation, and meet the demands of the real world.
If you have ever been told your labs look fine while your body tells a very different story, this episode offers language, clarity, and validation.
