A clinical reference manual that can help with interpretation of test results, development of treatment plans for patients, identification of possible causes of symptoms & conditions, & more. The Metametrix Handbook is a companion to the new Laboratory Evaluations in Integrative & Functional Medicine textbook (Lord & Bralley, 2008), which is a revision, update & expansion of the original textbook. Both the handbook & textbook cover tests to evaluate nutrients, toxicants, detoxification & biotransformation ability, adverse food responses, & gastrointestinal & hormonal functions. The handbook's quick-reference format complements the textbook's in-depth discussions & nearly 3800 literature citations.
