: Cadmium [Mass or Content] in Tissue by Mass Concentration Measurement

: What Is Being Measured

: Cadmium is a naturally occurring metal found in small amounts in soil, water, and air, and also in cigarette smoke and some industrial workplaces. The body does not clear cadmium efficiently, so repeated exposure can lead to accumulation, especially in organs such as the kidneys and liver. This test detects and quantifies cadmium in a tissue specimen.

: Why the Test May Be Ordered

: A healthcare provider may order tissue cadmium testing when there is concern about significant exposure, such as occupational contact, smoking history, or known environmental exposure. It is one part of a broader evaluation and is usually interpreted together with other tests and a detailed exposure history.

: How the Sample Is Collected

: Because the slug indicates a tissue measurement, the specimen is a tissue sample rather than blood or urine. The exact collection method depends on the clinical setting and the provider's request, and a trained professional obtains and prepares the sample according to laboratory instructions.

: What Results Can Mean

: Results indicate the amount of cadmium detected in the tissue sample relative to the laboratory's reporting method. Higher levels generally suggest greater accumulation or exposure, but results must be interpreted by a clinician in the context of symptoms, exposure history, and other laboratory findings. This test does not by itself diagnose a specific disease.
