Electrolyte Panel
Electrolytes are minerals that have an electrical charge when they are dissolved in water or body fluids.
Electrolytes are minerals that have an electrical charge when they are dissolved in water or body fluids. You have electrolytes in your blood, urine, tissues, and other body fluids. They are important because they help: Balance the amount of water in your body Balance your body's acid-base (pH) level Move nutrients into your cells Move waste out of your cells Support your muscle and nerve function Keep your heart rate and rhythm steady Keep your blood pressure stable Keep your bones and teeth healthy Electrolytes are in your blood, urine (pee), tissues, and other body fluids. An electrolyte panel is used to check for electrolyte, fluid, or pH imbalances. An electrolyte panel, also known as a serum electrolyte test, is a blood test that measures levels of the body's main electrolytes: Sodium , which helps control the amount of fluid in your body. It also helps your nerves and muscles work properly. Chloride , which also helps control the amount of fluid in your body. In addition, it helps maintain healthy blood volume and blood pressure. Potassium , which helps your cells, heart, and muscles work properly. Bicarbonate , which helps maintain your body's acid- base balance (pH). It also plays an important role in moving carbon dioxide through the bloodstream. Calcium , which helps make and keep your bones and teeth strong. Magnesium , which helps your muscles, nerves, and heart work properly. It also helps control blood pressure and blood glucose (blood sugar) levels. Phosphate , which works together with the mineral calcium to build strong bones and teeth. You get these electrolytes from the foods you eat and the fluids you drink. The levels of electrolytes in your body can become too low or too high. This can happen when the amount of water in your body changes. The amount of water that you take in should equal the amount you lose. If something upsets this balance, you may have too little water ( dehydration ) or too much water (overhydration). Abnormal levels of any of these electrolytes can be a sign of a serious health problem, including kidney disease , high blood pressure , and a life-threatening type of arrhythmia (irregular heartbeat). Other names: serum electrolyte test, electrolyte blood test, electrolyte lab test, lytes, sodium (Na), potassium (K), chloride (Cl), carbon dioxide (CO2)
Why is this test ordered? You may need this test if you have symptoms indicating that your body's electrolytes may be out of balance. These include: Nausea and vomiting Confusion and irritability Weakness Irregular or fast heartbeat (arrhythmia) Diarrhea or constipation Fatigue Headaches Muscle weakness, cramps , or spasms Numbness or tingling in your arms, legs, fingers, and toes
Clinical Interpretation
Your results will include measurements for each electrolyte. Abnormal electrolyte levels can be caused by many different conditions, including: Dehydration. Kidney disease. Heart disease . Diabetes . Lung infection (such as tuberculosis ). Malabsorption , a condition in which your body is not getting enough nutrients from the foods you eat. Liver disease . Acidosis, a condition in which you have too much acid in your blood. It can cause nausea, vomiting, and fatigue. Alkalosis, a condition in which you have too much base in your blood. It can cause irritability, muscle twitching, and tingling in the fingers and toes. An electrolyte imbalance can also happen if you take certain medicines, such as: Antibiotics Antacids, especially if you take large amounts Chemotherapy medicines Diuretics ("water pills"), which are used to treat high blood pressure and other conditions Steroid medicines Your specific results will depend on which electrolyte or electrolytes are affected and whether levels are too low or too high. If your electrolyte levels were not in the normal range, it doesn't necessarily mean you have a medical problem needing treatment. Many factors can affect electrolyte levels. These include taking in too much fluid or losing fluid because of vomiting or diarrhea. Also, certain medicines such as antacids and blood pressure medicines may cause abnormal results. An electrolyte imbalance means that the level of an electrolyte is too low or too high. The names of the imbalances are: Electrolyte Too low Too high Bicarbonate Acidosis Alkalosis Calcium Hypocalcemia Hypercalcemia Chloride Hypochloremia Hyperchloremia Magnesium Hypomagnesemia Hypermagnesemia Phosphate Hypophosphatemia Hyperphosphatemia Potassium Hypokalemia Hyperkalemia Sodium Hyponatremia Hypernatremia If you have questions about your results, talk to your provider.
