Resources We Rely On
Resources We
Rely On
Every range, threshold, and recommendation on MyHealthChart traces back to a named clinical authority — never a guess. Here’s exactly which organizations we cite, and which tool or guide each one powers.
Clinical & Government Health Authorities
We build our tools directly on published guidelines from these bodies — not on secondhand summaries. When a guideline updates, we update the tool.
World Health Organization
Global public health guidance and standardized growth and weight-classification references.
Powers: our BMI formula and weight-status categories.
American Heart Association
Sets the U.S. clinical standard for cardiovascular risk and blood pressure classification, updated in 2024.
Powers: our Blood Pressure Chart categories, from Normal to Crisis.
American Diabetes Association
Defines glucose and HbA1c ranges used to screen for prediabetes and diabetes.
Powers: our Blood Sugar Calculator and Blood Sugar Checker.
Centers for Disease Control
U.S. federal reference for screening intervals, risk factors, and preventive-care benchmarks.
Powers: screening guidance across our Health Conditions guides.
NHS (United Kingdom)
Plain-language, patient-facing symptom guidance we cross-check for clarity, not just accuracy.
Powers: the urgency flags in our Symptom Checker.
Endocrine Society
Clinical practice guidelines for hormone, thyroid, and vitamin reference ranges.
Powers: Vitamin D and hormone panels in our Lab Result Interpreter.
How We Choose a Source
We only cite peer-reviewed, government, or professional-society guidelines — never forums, press releases, or unverified claims. Every article lists its sources, and every tool names its guideline in the results screen.
