Heavy Metal & Mineral Testing There are two ways to interpret laboratory results, regular lab ranges and functional blood chemistry ranges. Conventional blood tests are used mainly for diagnosing disease for a long time. Functional Blood Chemistry Analysis is a new approach to identify underlying biochemical and nutritional imbalances that indicate health status. Functional Blood Chemistry Analysis helps to interpret blood test markers and understand these imbalances. Test values that fall between optimal ranges and pathological ranges are considered sub-clinical and may indicate the beginning stages of disease. Unlike conventional blood analysis, which uses broad reference ranges to diagnose a disease, the functional blood chemistry analysis approach is to identify the root cause of symptoms and applies a functional approach to rebalance and restore health.
