Gadolinium Test

Gadolinium is used in magnetic resonance imaging contrast agents. It is normally bound to a chelator, which is a molecule that helps the body eliminate it through urine.

In some individuals, gadolinium may dissociate and deposit in tissues. Elevated urine gadolinium reflects recent imaging or ongoing retention.

In patients with kidney disease, clearance is reduced, increasing the risk of nephrogenic systemic fibrosis, a condition involving skin and organ thickening.
