How can you tell if electrolyte levels are balanced in the body?

Electrolyte levels in the body can be determined through blood tests that measure the concentrations of key electrolytes such as sodium, potassium, and chloride. These tests can help healthcare providers assess whether electrolyte levels are within the normal range, indicating a balanced state in the body. Symptoms such as muscle weakness, fatigue, and abnormal heart rhythms may also suggest an imbalance in electrolyte levels.
