Special Info
Diet, medication and nutritional supplements may introduce interfering substances. Patients should be encouraged to discontinue nutritional supplements, vitamins, minerals and nonessential over-the-counter medications (upon the advice of their physician). High concentrations of iodine may interfere with elemental testing. Abstinence from iodine-containing medications or contrast agents for at least 1 month prior to collecting specimens is recommended. ARUP studies indicate that refrigeration of urine alone, during and after collection, preserves specimens adequately, if tested within 14 days of collection. Urine collected within 48 hours of administration of a gadolinium (Gd) containing contrast media (may occur with MRI studies) and acid-preserved samples are unacceptable. Specimens contaminated with blood or fecal material are unacceptable. Also unacceptable are specimens transported in non-trace element-free transport tubes (with the exception of the original device). This test is New York DOH approved.
Clinical Info
Urine aluminum may be useful for monitoring aluminum exposure and is preferred in the assessment of chronic exposure. Elevated levels should be confirmed with a second specimen due to a high susceptibility of specimen to collection related environmental contamination.
