Lab reference intervals
Laboratory ranges describe how results are evaluated in a clinical context. They are not a complete assessment of symptoms, lifestyle or performance.
Laboratory reference intervals are commonly used to help interpret test results. A value within a reference interval does not automatically explain how someone feels or performs.
IOH optimal ranges
Health Cartel uses the IOH Bloodwork Sheet 2026 v2 as its internal framework for functional pattern review. These targets are not diagnostic thresholds and should not be confused with validated clinical reference intervals.
Patterns matter more than a single number
We look at relationships between relevant biomarkers and the person behind the results. A functional hypothesis is not proof of a cause.
FREQUENTLY ASKED QUESTIONS.
Does a normal blood test rule out health problems?
No. Test interpretation depends on the marker, clinical context and the question being investigated.
Are IOH optimal ranges the same as medical reference ranges?
No. They serve a different, non-diagnostic purpose in our coaching framework.
