Introduction to Functional Lab Tests

This section contains excerpts from Dr. Weyrich's notebook of naturopathic and functional diagnostic medicine. It represents a snapshot of Dr. Weyrich's ongoing studies in functional diagnostic medicine that may be of interest to patients and other medical professionals.

Beware that most labs have two prices - "cash" and "list" with the list price being substantially higher. If you ask the lab to bill insurance and the insurance pays less than the list price, then the lab will "balance bill" you for the remainder of the list price. It is safer to always pre-pay cash and then submit the receipt to insurance for reimbursement.
