Potassium urine test
A potassium urine test checks the level of potassium in your body. Potassium is an important element in cell metabolism, and it’s important in maintaining the balance of fluids and electrolytes in your body. Having too much or too little potassium can be bad. Getting a urine test to determine the amount of potassium in your body can help you alter your potassium levels for better overall health.
For a 24-hour urine sample, you will collect all of your urine from a 24-hour window into a large container. To do this, you will begin your day by urinating into a toilet. After that initial urination, you will begin collecting your urine every time you urinate. After 24 hours, you will turn over your collection container to a nurse or lab technician and it will be sent for testing.
A normal potassium range, or reference range, for an adult is 25–125 milliequivalents per liter (mEq/L) per day. A normal potassium level for a child is 10–60 mEq/L. These ranges are only a guide, and actual ranges vary from doctor to doctor and lab to lab. Your lab report should include a reference range for normal, low, and high potassium levels. If it doesn’t, ask your doctor or lab for one.
Following a potassium urine test, your doctor may also request a potassium blood test if they think it will help confirm a diagnosis or detect something that the urine missed.
