The blood sample can check to see whether your potassium levels are in the normal range. What Is Potassium? As a nutrient, potassium is found in a number of foods. Some foods with a lot...
The normal potassium level for an adult ranges from 3.5 to 5.2 mEq/L (3.5 to 5.2 mmol/L). Potassium levels between 3 and 3.5 mEq/L (3 to 3.5 mmol/L) are considered mild hypokalemia. Anything lower than 3 mEq/L (3 mmol/L) is considered severe hypokalemia.
Normal serum concentrations of potassium range from about 3.6 to 5.0 mmol/L and are regulated by a variety of mechanisms [3,7].
To help you determine if your potassium is in a normal range, here's a breakdown of low, normal and high levels of the nutrient.
A typical potassium level for adults is between 3.5 and 5.0 millimoles per liter (mmol/L). Hyperkalemia occurs when potassium levels go above 5.5 mmol/L. A potassium level above 6.5 mmol/L can cause heart problems that require immediate medical attention. How common is hyperkalemia? In the general U.S. population, hyperkalemia is rare.
Although each laboratory differs, most will consider potassium measurements between 3.8 and 5.2 milliequivalents per liter of blood as normal. And if you haven’t had bloodwork done, muscle weakness is a key symptom that can indicate your potassium levels might be an issue.
A potassium blood test measures how much potassium is in your blood. The test is often part of a group of routine blood tests called an electrolyte panel. It may be used to monitor or diagnose conditions related to abnormal potassium levels.
A normal potassium level is between 3.6 and 5.2 millimoles per liter. It’s important to note that individual laboratories may use different values.
The normal level of potassium has a narrow range, as it is critical to the function of nerve and muscle cells, most importantly those in the heart. If the level is higher or lower than...
The reference range for a normal potassium can vary somewhat between labs, but is most often in the range of: 3.5 mEq/l to 5.0 mEq/l in adults 3.4 mEq/l to 4.7 mEq/l in children
