Who this is for
Anyone who's had more than one OligoScan and isn't sure how to interpret the comparison report, or anyone deciding whether a single test is enough versus retesting after a period of targeted support.
Why movement matters more than any single reading
A single test result is one photograph. It tells you where things stood on that specific day, under whatever conditions you happened to be in. It can't tell you whether you're improving, stable, or declining — for that, you need a second photograph to compare it to.
This isn't a fringe idea. Mainstream chronic-disease management works the same way: an HbA1c value on its own is informative, but tracking it every few months is what actually tells a physician whether a diabetes management plan is working. The same logic applies here. As one clinical author focused on chronic disease interpretation puts it: if you're unsure what's going on, look at the movement of the values from one report to the next — the movement is what tells you the most about the underlying process.
Once two OligoScan reports exist for the same person, minerals, heavy metals, vitamins, and ratios can all be compared directly, with the goal being movement toward the "OK" range in the center of the chart. Algorithm scores are not compared between scans — they're read individually, each time, in the context of current symptoms.
The pattern that trips people up: rising heavy metals aren't automatically bad news
This is the single most counterintuitive part of reading a comparison report, and it's worth sitting with. When a heavy metal reading is lower on a follow-up scan, that's usually straightforward — it suggests the body is successfully clearing it. But when a heavy metal reading is higher on a follow-up scan, that can mean one of two very different things, and they point in opposite directions:
- The metal is mobilizing out of deeper tissue and into the periphery — often an early, expected part of a detox process, especially if elimination support is in place.
- The metal has moved but isn't actually being cleared — mobilization without adequate elimination, which is exactly the caution already built into how VIGEO frames detox: moving a metal is not the same as removing it, and when binding and elimination can't keep pace with what's been stirred up, people often feel worse partway through, not better.
The difference between these two isn't visible in the number alone. It depends on what else is happening — symptoms, timeline, and whether the elimination pathways (liver, kidneys, gut, sweat, lymph) are actually functioning well enough to carry the metal the rest of the way out.
Vitamins can show a similar dual meaning. A decline in vitamin levels between two scans can reflect poor diet or absorption — or it can reflect vitamins being actively consumed to fuel a detox process already underway. Same direction of movement, two very different explanations.
A framework worth naming honestly: Hering's Law
One lens sometimes used to interpret this kind of pattern comes from Constantine Hering, a 19th-century physician associated with homeopathic medicine. The idea, often summarized as "direction of cure," holds that healing tends to move from more vital organs outward to less vital ones — so an improvement in something like mental clarity, paired with a temporary worsening in something more peripheral like muscle pain, can be read as the body prioritizing repair in the right order rather than as a treatment failing.
Being direct about where this comes from: this is a interpretive framework from classical homeopathy, not an established biomedical mechanism with clinical trial support behind it. It's a useful lens for organizing what a comparison report and a symptom timeline are showing together — not a proven law of physiology. Worth knowing the difference before leaning on it too heavily in a client conversation.
A few illustrative patterns
The book's case-study chapter on common trends is explicit that this is an area of ongoing clinical observation — several patterns are working hypotheses based on recurring cases, not settled fact. A few that come up often:
- Mercury and silver rising together often shows up in people with dental amalgam fillings, since amalgam contains both.
- Copper and zinc moving in opposite directions is the classic mineral blockade pattern — covered in full here.
- A vegan or vegetarian diet tends to produce its own recognizable mineral signature, distinct from someone eating an omnivorous diet, which matters when deciding whether a "low" reading reflects a real deficiency or an expected dietary pattern.
These are pattern-recognition tools, not diagnoses — a comparison report is a prompt to ask a better question, not an answer on its own.
When should you actually retest?
Most people retest after a period of targeted support — typically several months — so there's been real time for change to occur. For repeat scans to be meaningfully comparable, use the same hand and similar conditions each time; comparing a post-illness scan to a well-rested baseline scan tells you about that one event, not about your overall trajectory.
What this article does not tell you
- A comparison report doesn't diagnose anything. It shows movement, not a medical conclusion.
- Two data points is a trend line, not proof. More scans over time make a pattern more reliable, not less.
- Several of the interpretive patterns discussed here — including Hering's Law and specific case-study patterns — are working hypotheses, not settled clinical fact. They're offered as a way to think through what's changing, not as certainties.
- This doesn't replace medical evaluation. If something in a comparison report is concerning, that's a conversation for your physician, not a self-directed response.

Questions and Answers
Q: What's the most important thing to look at when comparing two OligoScan reports? A: The direction of movement matters more than any single number. A value moving toward the "OK" range in the center of the chart is generally a positive sign; movement away from it is worth investigating alongside symptoms and other test results.
Q: If a heavy metal reading goes up on a follow-up scan, is that bad? A: Not necessarily. It can mean the metal is mobilizing out of deeper tissue as an early part of detox, or it can mean it's being redistributed without being effectively eliminated. The number alone can't distinguish between the two — symptoms and elimination support matter too.
Q: What is Hering's Law, and is it proven science? A: It's a 19th-century concept from classical homeopathy describing healing as moving from more vital organs outward. It's used here as an interpretive lens for reading symptom patterns alongside test comparisons, not as an established biomedical mechanism.
Q: How often should you retest? A: Most people retest after several months of targeted support, using the same hand and similar conditions each time for a meaningful comparison.
