What Your Results Can and Can't Tell You

Lab results are an important part of understanding your health, but they are only one part. A number inside the reference range does not always mean everything is fine, and a number slightly outside it is not always a problem. Results are most useful when they are read alongside your symptoms, history and goals.

The guides below explain what common tests measure, how results are typically interpreted and which questions to ask your provider. They are organized into hormone labs, metabolic and thyroid labs, and general tips for reading your results.
