The reference ranges on the Environmental Toxins tests are based either on Vibrant America's internal validation study or results from the National Health and Nutrition Examination Survey (NHANES).
NHANES survey conducts urine and blood biomonitoring in a nationally representative sample of Americans. NHANES measures several environmental toxins. The use of NHANES data for reference ranges allows ordering providers and patients to compare heavy metal and environmental toxin exposure results to the general population.
All other analytes on the Environmental Toxins report use the Vibrant Wellness internal validation study of 1,000 adults. Specifically, the analyte levels of 1,000 healthy individuals were measured and plotted on a Gaussian curve.
- In Control: Levels that are less than the 75th percentile.
- Moderate: Levels between the 75th and 95th percentile.
- High: Levels greater than the 95th percentile.
