When working with clients I generally first just want to see a CBC (Comprehensive Blood Count) and as big a CMP (Comprehensive Metabolic Profile) as their doctors are willing to order. (CMPs are available with a varying number of tests.) From these, I can get a decent -- not perfect, but pretty good -- idea of hydration status, blood sugar/insulin control, inflammation, stomach acid status, and certain nutrient insufficiencies. If I see anything of concern on these, I have clients either request from their doctors, or order on their own, other more specific markers. One thing I DO like to add is a more detailed look at thyroid function. Doctors generally only include Thyroid Stimulating Hormone (TSH), though some doctors do more. I like to see a Free T4 and Free T3 (emphasis on the "Free") in addition to TSH. If you think that stress is a big issue for you, a Reverse T3 would be very helpful. When I interpret results for clients, I use different reference ranges than the standard ones. Dicken Weatherby, ND and Scott Ferguson, ND have published a useful book (except for thyroid), called, Blood Chemistry and CBC Analysis
, that I use to guide me.
From here, your options multiply enormously, and your insurance company often stops footing the bill, which is why I start with standard labs and proceed as necessary. There are many different types of tests that are considered "functional," i.e., they demonstrate how different parts of your body are actually functioning, versus whether or not you've reached an actual disease state (standard tests and reference ranges). These measure blood, urine, saliva, and/or hair and are individually determined based on need.
I also suggest questionnaires first, as a helpful means of honing in on what needs to be tested. Any of the Bauman questionnaires throughout the textbooks and workbooks are recommended, as well as some detailed ones you can access online and in books. Of particular interest are the ones for Candida (http://www.yeastconnection.com/pdf/yeastfullsurv.pdf
) and adrenal fatigue (http://www.adrenalfatigue.org/take-the-adrenal-fatigue-quiz
