Mineral Tests

  • Trace Elements Urine, Post Chelation UMEP

    A 24-hour urine test for measuring nutritional and toxic mineral (elements) after I.V. treatment with EDTA. These results are usually compared to the pre-chelation results. The profile includes aluminium, cadmium, calcium, chromium, copper, iron, lead, magnesium, manganese, and zinc. The post ...

  • Trace Elements – Urine, Pre & Post Chelation UMEP

    For pre chelation, the 24-hour period begins immediately after the patient has urinated to empty his/her bladder. This first urination specimen is not collected. It is discarded. Subsequent urination specimens are to be collected for testing. Refer to instructions for Trace elements- Urine Post ...

  • Copper, RBC

    Deficiency symptoms of copper may include anemia, fatigue, fragile bones and blood vessels, and lower disease resistance. Copper toxicity results in nausea, vomiting, epigastric burning and diarrhea. Classic conditions associated with copper deficiency are MenkeÆs syndrome and WilsonÆs disease. ...

  • Magnesium, RBC

    Magnesium is the fourth most abundant cation in the body and is second only to potassium within the cell. The adult human body contains 21 to 28 grams of Mg. Of this, 60% is in the bones, 20% in the skeletal muscle, 19% in other cells and about 1% in the extracellular fluid. Magnesium is […]

  • Manganese, RBC

    The Manganese (Mn) content in the adult human is 12 to 20 mg. About 25% is stored in the skeleton. Within each cell, Manganese is concentrated in the mitochondria. Bone, liver and pancreas tend to have the highest concentrations. Deficiency symptoms are unclear. There may be blood clotting ...

  • Selenium, RBC

    Selenium (Se) is a constituent of glutathione peroxidase, an antioxidant enzyme that breaks down hydrogen peroxide, phospholipid hydroperoxides and other free hydroperoxides. There are four selenium atoms in glutathione peroxidase. There are three types of iodothyronine deiodinase. It removes ...

  • Strontium, Urine

    The action of strontium, a trace mineral, is closely related to that of calcium and the retention of strontium varies inversely with intake. It affects the osteoporetic process by inhibiting the activity of the 24, 25 hydroxy forms of vitamin D3 in animals. It has been shown that treating ...

  • Zinc, RBC

    Zinc is important in DNA and protein synthesis, fertility, skin growth, healing, taste buds, protein digestion, carbon dioxide removal, disease resistance, immunity, etc. Too much calcium, copper or fiber in the diet, or the use of oral contraceptives may increase the need for zinc. Deficiency ...

  • Zinc, Serum

    Zinc is second to iron as being the most abundant trace mineral present in the body. It is an important component of nearly 300 enzymes in different species. It is found in high concentrations in the prostate, semen, liver, kidney, hippocampus, retina, bone and muscle. Zinc is important in DNA ...

  • Hair Tissue Analysis

    Hair mineral analysis examines for five toxic minerals and 11 nutritional elements. Since hair grows about one centimeter a month, and is an excretory tissue, two inches of hair cut from the nape of the neck between the ears, indicates the toxic or mineral nutrition status of an individual for ...

  • Copper, Serum

    Copper is a trace mineral and is associated with a number of metalloproteins, whose major functions involve oxidation-reductions in many important enzymes. It is also associated with iron in red blood cell formation, energy release, and is important in the synthesis of melanin, nerve coverings, ...

  • Calcium, RBC

    Calcium forms structural salts for bones and teeth. It is essential for growth, blood-clotting, muscle contraction, nerve transmission, cell membrane permeability, and is a catalyst in many reactions. Decreased levels may cause weak bones and teeth, stunted growth, early tooth loss, muscle ...

  • Boron, Urine

    Urine boron testing has gained popularity due to claims that it can strengthen bones, build muscle mass, increase brain activity, strengthen the immune system, increase calcium absorption from foods and lowers the amount of calcium excreted from the body. Boron is a trace mineral and is ...
