  1. Laboratory Assessment Suggestions
    1) Thyroid Testing– Make sure ALL Thyroid tests ordered.
    Most docs do not know how to interpret these tests.
    TSH; Total T4; Free T4; Total T3 (T3 Uptake); Free T3 ;
    Reverse T3; & Thyroid antibodies
    2) Other Lab tests to consider:Vit D3 level (critical); Hemoglobin A1C;
    Testosterone Free and Total; Sex Hormone Binding Globulin; DHEA-S; Estradiol, Progesterone, FSH / LH; Prolactin 

3) Hormone Testing –
Make sure you get ALL your hormones measured and their metabolites – i.e. cortisol’s X 4, Estrogen and Testosterone metabolites;  Some of the metabolite ratios are very predictive of breast and prostate cancer

4) Environmental toxicity
Great Plains Labs GPL-TOX: TOXIC NON-METAL CHEMICAL Profile & Glyphosate level

Glyphosate test

Sample report

Every day, we are exposed to hundreds of toxic chemicals through products like pharmaceuticals, pesticides, packaged foods, household products, and environmental pollution.  As we have become more exposed to chemical-laden products and to toxic chemicals in food, air, and water, we have been confronted with an accelerating rate of chronic illnesses like cancer, heart disease, chronic fatigue syndrome, chemical sensitivity, autism spectrum disorders, ADD/AD(H)D, autoimmune disorders, Parkinson’s disease, and Alzheimer’s disease.  This chemical profile that screens for the presence of 172 different toxic chemicals including organophosphate pesticides, phthalates, benzene, xylene, vinyl chloride, pyrethroid insecticides, acrylamide, perchlorate, diphenyl phosphate, ethylene oxide, acrylonitrile, and more.  This profile also includes Tiglyglycine (TG), a marker for mitochondrial disorders resulting from mutations of mitochondrial DNA.  These mutations can be caused by exposure to toxic chemicals, infections, inflammation, and nutritional deficiencies.|


4) Heavy Metals testing – Genova (I suggest doing a DMSA challenge (chelates metals, increasing chance of finding them à Need Rx for DMSA). I missed my heavy metal toxicity 5 yrs. ago doing a regular urine test and no chelation)
You do a baseline urine collection, take DMSA and repeat a urine collection in 6 hrs.

5) GI Effects or CSDA Stool analysis Doctors Data)

6) Mold

A) Do visual screening ($15 and takes 10 min on computer).

The VCS Test – Visual Contrast Sensitivity – The online VCS Test is a measure of one of the neurologic functions of vision called contrast.  In order to take this test, your corrected visual acuity must be better than 20:50. There must be adequate illumination.   The test is taken with one eye covered and one open at a distance of 18” from the computer screen. It is a ”Pass/Fail,” though how well you do can be used to assess your improvement over time or worsening with re-exposure/repeat illness.
 You need to know that the computer version of the VCS test is a screening test and is not used to diagnose any condition.  If you are concerned about the possibility of a biotoxin associated illness you will need to be examined by a physician experienced in the field.  We recommend your VCS testing results be validated for you by use of a hand held VCS test.

B) Urine mycotoxins – Real Time Labs
(measures the toxic exposures in your body)

C) HLA – Immunoglobulin’s (20% of population is genetically sensitive to mold)

D) TGF-Beta 1; VIP; Anti-Diuretic Hormone; MMP9; VEGF; MSH;
