COBALT (SERUM)

The COBALT (SERUM) test measures the concentration of cobalt, a trace metal, in the blood serum to detect and monitor systemic exposure. A venous blood sample is analysed in an accredited laboratory using sensitive techniques (typically ICP‑MS) to quantify cobalt at trace levels, enabling detection of elevated exposure that can affect multiple organs. Monitoring serum cobalt is important for people with metal‑on‑metal orthopedic implants, occupational or environmental exposure, and for assessing potential causes of unexplained cardiac, neurological, liver or kidney dysfunction.

This test is suitable for patients requiring routine surveillance after joint replacement, workers in industries with cobalt use, and individuals with symptoms suggestive of metal toxicity. Results help clinicians decide on further investigations, implant management or exposure-reduction measures and are provided with professional interpretation guidance to support timely clinical decisions in the UAE healthcare context.

Lab reference ranges and clinical interpretation can vary; mildly elevated results may prompt repeat testing or correlation with symptoms, imaging and organ function tests (liver, kidney, cardiac). Always review results with your treating physician — serum cobalt alone does not establish a diagnosis and should be considered alongside clinical findings and other laboratory data.
