Cadmium, Random Urine
Also known as: U CAD RAND
Use
This test is useful in the assessment of chronic exposure to cadmium and determination of the cadmium body burden. In chronic exposures, the kidneys are the primary target organ, and urine cadmium concentrations can be indicative of cadmium toxicity. Symptoms vary based on exposure route and include tubular proteinuria, fever, headache, dyspnea, chest pain, conjunctivitis, rhinitis, sore throat, and cough. Ingestion of high concentrations of cadmium may cause vomiting, diarrhea, salivation, cramps, and abdominal pain.
Special Instructions
Not provided.
Limitations
Elevated cadmium results may arise from skin or collection-related contamination, such as using non-trace element-free containers. If contamination is suspected, a second specimen collected in trace element-free containers should confirm results. High iodine concentrations may interfere with elemental tests.
