Sodium plays a very critical function in maintaining blood pressure. In addition it also regulates muscle and nerve functioning. Sodium holds water in the blood and high levels
increases the blood volume thereby increasing the pressure.
The human body regulates sodium level extremely carefully to maintain optimum levels. The kidneys play a critical role in eliminating sodium when blood levels are high and retain sodium when levels drop. A sodium test is always ordered in combination with other electrolytes like potassium, chloride and bicarbonates. A measurement of these electrolytes gives an indication of electrolyte imbalance which in turn gives information on conditions involving brain, lungs, liver, heart, kidney and thyroid.
