Lab Reference Library

Standard laboratory reference ranges are calculated from large population samples. They define where most people fall, not where people feel and function best. Functional medicine optimal ranges are narrower targets derived from clinical outcomes research. You can be well within the standard range and still have significant dysfunction. That gap is exactly what this library is designed to address.

This library is a clinical education resource. The information here will help you understand what your markers mean, what the optimal targets are, and what factors drive results in either direction. However, lab results should always be interpreted in clinical context by a qualified provider who knows your full history, medications, and presentation. Use this to get informed, then schedule a consultation to get interpreted.

Yes. As a cash-based functional medicine practice, Dr. Lamkin is not constrained by insurance authorization requirements when ordering labs. We build panels based on clinical need and individual patient presentation, not coverage policies. We also partner with specialty labs including Rupa Health for direct-access testing.

Reference ranges and clinical interpretation are reviewed and updated as new research becomes available. Each page is authored and reviewed by Brian Lamkin, DO, and reflects current functional medicine practice standards.

This library is actively being built. Pages are added on an ongoing basis, prioritized by clinical frequency and patient search volume. If a lab you are looking for is not yet available, contact us and we will add it to the queue.
