The Electrolyte Test measures the levels of three essential electrolytes in your blood, providing valuable information about your body's health status. This test assesses levels of chloride, potassium, carbon dioxide and sodium. Understanding your electrolyte levels can help identify electrolyte imbalances that may affect fluid balance, nerve and muscle function, blood pressure and overall health.
Preparation: No special preparation needed.
An electrically charged mineral (electrolyte) that helps regulate fluid and acid-base balance within the body.
An electrically charged mineral (electrolyte) vital to a cell’s ability to take in nutrients and remove waste; it is also essential for muscle function and regulating fluid balance.
A waste product created by the body’s metabolism that helps maintain the body’s acid-base balance (pH) in the form of the electrolyte bicarbonate.
An electrically charged mineral (electrolyte) necessary for healthy muscle and nerve function that also helps maintain fluid balance.
Signs of electrolyte imbalances are often subtle and could be indicators of other health issues. Symptoms such as muscle weakness, irregular heartbeat or fatigue may be related to electrolyte imbalances and can often go unnoticed.
An electrolyte panel is typically part of a routine blood test or physical exam, or as part of a comprehensive metabolic panel (CMP), and can help you and your healthcare provider determine your next steps for improved health.

While 6 in 10 adults have a chronic disease and 4 in 10 have two or more, understanding your electrolyte balance can guide changes in lifestyle and behavior for better health.1
Electrolytes like sodium, potassium, and chloride are crucial for proper hydration, nerve and muscle function, blood pressure and overall health. Testing these levels can help you understand your body's electrolyte balance and make informed decisions about your overall health.

An electrolyte imbalance means that the level of one or more electrolytes in your body is too low or too high. Symptoms can vary but may include muscle cramps, weakness, irregular heartbeat, fatigue, confusion, and in severe cases, seizures. However, these symptoms may be associated with various health conditions, so it's important to consult with a healthcare provider for proper evaluation.
Some medications can affect electrolyte levels in the body. If you're taking certain medications, particularly diuretics, heart medications, antibiotics or corticosteroids, testing can help check if your electrolyte levels are in the optimal range.
