Description
Overview:
Cadmium is a toxic heavy metal found in batteries, metal coatings, and cigarette smoke. Unlike some toxins that the body clears quickly, Cadmium accumulates over time, specifically damaging the kidneys and bones. Because the kidneys filter Cadmium from the blood, a urine test is the most reliable way to assess the body’s total burden of this metal.
Clinical Significance:
-
Heavy Metal Toxicity: High levels indicate dangerous exposure.
-
Kidney Damage: Chronic exposure can lead to kidney failure. This test is often performed alongside a “Urine Creatinine” test to correct for urine concentration (how much water you drank), ensuring accurate results.
-
Occupational Safety: Essential monitoring for workers in smelting, welding, battery manufacturing, or electroplating industries.
When is this test recommended?
-
Occupational Health: Routine screening for industrial workers.
-
Symptoms of Toxicity: If a patient presents with kidney dysfunction, fragile bones (osteoporosis), or unexplained lung issues.
-
Smokers: Heavy smokers are at higher risk of Cadmium accumulation.
Sample Requirements:
-
Specimen: Random Urine Sample (Spot Urine).
-
Container: Sterile Urine Container (Plastic cup with screw cap).
-
Preparation:
-
No fasting required.
-
Important: Avoid eating seafood (especially shellfish) for 48 hours before the test, as it can temporarily raise heavy metal levels.
-
Wash hands thoroughly before collection to avoid contaminating the sample with external dust.
