    Test Description

    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 postmenopausal women with strontium ranelate leads to early and sustained reductions in the risk of vertebral fractures. Low levels have been found in patients with dental caries, decreased growth in animals, bone pain and osteoporosis. Toxic levels may cause dental caries, rickets, abdominal pain and diarrhea.

    No RDA has been established for strontium. An estimated mean daily intake of strontium worldwide from food and water is 1.0 mg to 5.0 mg per day. A therapeutic range is said to be from 10 mg to 2000 mg. Sources of strontium are most plant foods, dairy products, brazil nuts, and seawater.

    A 20-mL random or 24 hour urine specimen is required for this test.
