Sodium plays many important roles in the body. It maintains fluid balance and is a main nutrient used in nerve impulse transmission and muscle contraction. The normal range for blood sodium is between 135 and 145 mEq/L (3.10 mg/ml to 3.34 mg/ml). Higher levels of sodium are normally associated with hypertension. A sodium level of 150 mEq/L (3.45 mg/ml) or more is known as hypernatremia, a condition that is commonly caused by dehydration or eating too much salt. However it can also be caused by other conditions such as diabetes or hormonal imbalances.
Your doctor will evaluate your sodium by requesting a blood lab test. Sodium levels should be between 135 to 145 milliequivalents per liter, or mEq/L for short, although your lab may have slightly different values, MedlinePlus reports. A high sodium level indicates too much sodium in your diet, too much fluid loss or some sort of complication.
