What's this test for?

This test is ideal if you're being monitored for nutrition or protein needs, especially if you're critically ill or receiving intravenous nutrition. It helps estimate whether your body is breaking down more protein than it's taking in, which is called nitrogen balance. It can also be useful if you or someone managing your care wants a clearer picture of how your diet is affecting your body's protein status.

What happens after I get my results?

Your results will show up in your account with the normal range clearly explained next to your value. If your urea nitrogen level is outside the typical range, simple next steps include adjusting your protein intake, staying hydrated, and rechecking with a follow-up test after a few weeks to see if the change worked. If a result comes back extremely abnormal along with symptoms like severe weakness or swelling, treat that as a sign to seek medical care right away. You can download the full lab report from your account anytime, and the trends feature lets you track how your levels shift over time.

What symptoms indicate I may need this test?

You might consider this test if you're dealing with unexplained muscle loss, poor wound healing, or ongoing fatigue that could point to a protein or nutrition problem. It's also relevant if you have a condition affecting your kidneys, liver, or thyroid, since these can all change how your body handles protein waste. People on very restrictive diets or receiving nutrition through an IV are also good candidates.

How can I naturally support healthy nitrogen balance?

Eating a balanced amount of protein for your body size and activity level is the biggest factor, since too much or too little can throw off your results. Staying well hydrated helps your kidneys process and clear urea normally. Limiting excessive high-protein supplements or crash diets, and instead spreading protein intake evenly across meals, can also help keep levels steady.

When will I get my results?

Results are typically ready within about 7 days of your sample being tested at the lab. Once ready, they'll be posted directly to your online account where you can view and download them.

Who should consider this test?

This test is a good fit for people who are critically ill, hospitalized, or receiving nutrition through an IV line, since it helps guide how much protein they need. It's also useful for anyone working on managing a high-protein or low-protein diet who wants objective feedback on how their body is responding.

What is urinary urea nitrogen and why does it matter?

Urea is the main waste product left over after your body breaks down protein, and most of it leaves your body through urine. Measuring the urea nitrogen in a urine sample gives a snapshot of how much protein your body is processing and breaking down. This matters because it helps show whether you're getting enough protein or breaking down too much muscle.

What does high urinary urea nitrogen mean?

A higher than normal result can mean your body is breaking down more protein than usual, which can happen with excess protein in your diet, an overactive thyroid, or increased muscle breakdown from illness or injury. If this shows up, cutting back on very high-protein eating and rechecking your levels can help clarify if it was diet-related.

What does low urinary urea nitrogen mean?

A lower than expected result can point to not eating enough protein, a diet very high in carbohydrates and low in protein, liver problems, or kidney issues that affect how urea is processed. Pregnant people and healthy children can also naturally have lower levels without it being a concern. Reviewing your recent diet and protein intake is a good first step if your number comes back low.

How often should I retest?

If you're adjusting your diet or protein intake based on a previous result, retesting after 4 to 6 weeks is a reasonable timeframe to see if your changes made a difference. For people being monitored during IV nutrition or a hospital stay, retesting may happen more frequently as part of ongoing nutrition tracking. Use the trends feature in your account to see how your results change between tests.
