What's this test for?

This test is ideal if you're experiencing symptoms like excessive thirst, muscle weakness, swelling, or ongoing vomiting that may point to a fluid or electrolyte imbalance. It measures how much chloride your body is releasing in urine over a full day, which reflects how well your kidneys and hydration levels are balancing salt intake. It's often used when there's concern about dehydration, kidney function, or conditions affecting your body's acid-base balance.

How should I prepare for this test?

How can I naturally support healthy electrolyte and hydration balance? Staying consistently hydrated throughout the day helps your kidneys regulate chloride and sodium levels naturally. Eating a balanced diet with moderate salt, plenty of fruits and vegetables, and avoiding excessive processed foods can help keep your electrolytes steady. Regular movement and avoiding excessive sweating without replacing fluids also support healthy chloride balance.

What's included in this test?

This test measures the amount of chloride and creatinine in a urine sample collected over 24 hours. Chloride reflects your dietary salt intake and hydration status, while creatinine helps confirm that the urine collection was complete and accurate, making the chloride reading more reliable.

What happens after I get my results?

Your results will be available in your account, with each value's normal range clearly explained so you know exactly where you stand. If your chloride level is outside the expected range, simple next steps might include adjusting your fluid and salt intake, reviewing any medications that affect hydration, or retesting after a few weeks to confirm the pattern. If a result is extremely high or low, seek medical care promptly since this can signal a serious imbalance. You can download the standard lab report anytime and use the trends feature to track your levels over time.

When will I get my results?

Results for this test are typically ready within about 7 days after your 24-hour urine sample is received at the lab. This timeframe allows the lab to accurately process the full-day collection along with the creatinine measurement used to validate it. You'll be notified as soon as your results are posted to your account.

Who should consider this test?

This test is a good option for anyone with symptoms of dehydration, unexplained swelling, unusual fatigue, or digestive issues like prolonged vomiting or diarrhea. It's also useful if you have a known condition like heart failure, kidney disease, or an adrenal disorder and want to monitor how it's affecting your salt and fluid balance. People on certain medications that affect hydration or blood pressure may also benefit from this test.

What symptoms indicate I may need this test?

Common symptoms that might prompt this test include excessive thirst, dry mouth, muscle cramps or weakness, unexplained swelling in the legs or abdomen, and irregular heartbeat. Ongoing vomiting, diarrhea, or heavy sweating without adequate fluid replacement can also disrupt chloride levels. If you're experiencing any of these along with fatigue or confusion, this test can help identify an underlying imbalance.

What does high chloride mean?

A high chloride result in your urine often means your body is losing more salt and water than usual, which can happen with dehydration, certain kidney conditions, or hormonal imbalances like Addison's Disease. It can also show up with diabetic acidosis. Simple steps include increasing fluid intake, reviewing your diet, and retesting after making changes, but very high levels paired with symptoms like dizziness or confusion warrant prompt medical attention.

What does low chloride mean?

Low urine chloride can happen when your body is holding onto salt more than usual, which is often seen with congestive heart failure, heavy sweating, or prolonged vomiting that causes a condition called metabolic alkalosis. Adjusting your diet and fluid intake may help, and it's worth retesting to see if the level normalizes. If you have ongoing vomiting or heart-related symptoms alongside a low result, seek medical care.

How often should I retest?

If your first result comes back outside the normal range, retesting after a few weeks is a reasonable step to see if lifestyle changes have made a difference. If you're managing a known condition affecting your kidneys, heart, or hormones, periodic retesting every few months can help you track trends over time. The trends feature in your account makes it easy to compare results side by side.
