Welcome back to our weekly edition of Friday Field Notes.
This week inside our Doctor of Functional Medicine program, we're exploring mineral testing — the different ways practitioners can investigate essential minerals and trace elements, and what these findings may reveal about nutritional status and overall health. 🌿
Minerals play important roles in hundreds of processes throughout the body, from energy production and muscle function to nerve signaling, bone health, and metabolic activity.
Yet assessing mineral status isn't always as simple as ordering one test.
Different testing methods offer different pieces of the puzzle. The key is understanding which markers to evaluate, when to look beyond routine bloodwork, and how to interpret results in the context of the whole person.
Upon program completion, our graduates have access to both Rupa Health and Evexia— functional testing platforms that connect practitioners with a wide range of laboratory testing options.
Let's explore three ways practitioners investigate mineral status. 👇 |

| 🩸 Blood Chemistry & Mineral Markers
Sometimes, valuable clues are already available through routine bloodwork.
A Comprehensive Metabolic Panel (CMP) measures several important minerals and electrolytes, including:
- Sodium & Potassium — Help regulate fluid balance, nerve signaling, and muscle function.
- Chloride & Bicarbonate — Help maintain fluid and acid–base balance.
- Calcium — Supports bones, muscles, nerve signaling, and heart function.
The CMP also measures glucose, proteins, liver enzymes, and markers of kidney function, offering a broader picture of metabolic health.
But here's the important distinction: CMP results reflect minerals circulating in the blood, not total body stores. Additional testing may be needed to assess minerals like magnesium, iron, zinc, and copper.
For a functional medicine practitioner, understanding what's included in routine bloodwork — and knowing when to look deeper — is an important part of connecting the dots. |

| 🔬 Specialized Micronutrient Testing
When routine bloodwork doesn't answer the question, specialized testing may provide additional information.
The SpectraCell Micronutrient Test, for example, evaluates nutritional status inside white blood cells, helping practitioners understand how well cells are using essential nutrients.
Depending on the clinical question, practitioners may also consider targeted testing for minerals such as manganese, chromium, zinc, and copper.
- Chromium — Testing may be considered in specific nutritional or exposure-related circumstances.
- Manganese — Assessment may be appropriate when deficiency, excess exposure, or impaired elimination is suspected.
- Copper-to-Zinc Ratio — Evaluating both markers together offers additional context, but the ratio isn't a stand-alone diagnostic tool.
The goal isn't to order every available test. It's to choose the right investigation for the question at hand and understand what the results can — and cannot — tell you. |

| 💇♀️ Hair & Urine Mineral Testing
Blood isn't the only specimen used to assess minerals.
Hair Tissue Mineral Analysis (HTMA) measures selected minerals and elements in a hair sample. It's used in some functional and integrative health settings to explore potential exposure patterns over time.
HTMA results can be affected by contamination, hair treatments, and testing methods, so they should be interpreted cautiously and not used alone to guide supplementation.
Urine testing has a role, too!
- Urine Mineral Testing — Timed or 24-hour collections can help assess the excretion of certain minerals, such as calcium or magnesium, when clinically appropriate.
- Exposure Assessment — Urine testing may help investigate exposure to specific elements, depending on the substance and timing.
- A Bigger Picture — Blood, urine, and hair tests measure different things. They're not interchangeable, and the best choice depends on the clinical question.
🤎 Mineral testing is about connecting the dots. Meaningful insights come from combining lab results with nutrition, lifestyle, symptoms, and personal history.
That's part of what students explore in our Doctor of Functional Medicine program — learning to interpret laboratory data, investigate underlying factors, and develop a more comprehensive understanding of health. 🌿 |
