Instructions:
Refrigerate during 24 hr collection in plastic container.
Diet, medication, and nutritional supplements may introduce interfering substances. Patients should be encouraged to discontinue nutritional supplements, vitamins, minerals, and non-essential 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 for elemental testing is recommended.
Studies indicate that refrigeration of urine alone, during and after collection, preserves specimens adequately, if tested within 14 days of collection.
Record start and stop of collection period on requisition.

Interpretive Data:
Urine cadmium levels can be used to assess cadmium body burden. In
chronic exposures, the kidneys are the primary target organ. Symptoms
associated with cadmium toxicity vary based upon route of exposure and
may include tubular proteinuria, fever, headache, dyspnea, chest pain,
conjunctivitis, rhinitis, sore throat and cough. Ingestion of cadmium
in high concentration may cause vomiting, diarrhea, salivation,
cramps, and abdominal pain.
