What does the Barium (Ba), Urine, Random test measure?

Why is Barium (Ba), Urine, Random measured?

Urinary barium is included in comprehensive toxic metals panels as an exposure marker. Significant barium elevation is associated with hypokalaemia-like effects — muscle weakness, cardiac arrhythmia, and hypertension — through potassium channel blockade. In the general population, elevated urinary barium most commonly reflects dietary sources (Brazil nuts are a particularly concentrated source) or contaminated drinking water. Occupational exposure assessment and water source investigation are the primary investigative responses to elevated urinary barium in clinical practice.
