The Purpose of an Electrolyte Panel

Do you ever feel out of balance? It could be that your body lacks electrolytes, the electrically charged minerals that are essential for healthy cell function, whether that’s moving your muscles during a workout or maintaining the proper pH levels. Without the right balance of electrolytes, you can suffer symptoms ranging from fatigue and nausea to arrhythmia and kidney problems. Because you need to get electrolytes in your daily diet—your body doesn’t manufacture them—it’s important to stay on top of your levels so you can make the right dietary choices that support your health.

What Does the Electrolytes Test Measure?

An electrolyte imbalance test typically measures four main minerals: sodium, potassium, chloride, and bicarbonate (which is made from carbon dioxide).

Who Should Take a Blood Test for Electrolytes?

You can order an electrolyte panel annually for routine health maintenance; this will help you take proactive measures quickly if an imbalance is detected. It may also be advisable to get an electrolytes test as part of a weight loss program or fitness regimen. Keep an eye out for symptoms of electrolyte balance that may require testing, which include:

  • Arrhythmia or an elevated heart rate
  • Muscle weakness, spasms, or cramps
  • Fatigue
  • Nausea and/or vomiting
  • Headaches
  • Disorientation
  • A numbing or tingling sensation in your extremities
  • Changes to your bowel habits

Electrolytes Labs Preparation

You don’t need to take any special measures to prepare for your electrolyte blood test. Talk with your doctor or the lab if you are on medications, however, as some types can affect your results.

Electrolyte Panel Test Results

While there are variations in the normal ranges for each electrolyte that is tested in the panel, here are some general guidelines:

  • Chloride: 97 to 105 mmol/L
