What's this test for?

This test is ideal if you're experiencing dark or reddish urine, unexplained fatigue, or signs of red blood cell breakdown in your body. It helps check for free hemoglobin in your urine, which can show up when red blood cells are being destroyed faster than normal. This can happen with certain infections, reactions to blood transfusions, or conditions that damage red blood cells.

How should I prepare for this test?

How can I naturally support healthy red blood cells? Staying well-hydrated helps your kidneys filter waste properly and can support overall urinary health. Eating iron-rich foods like leafy greens, beans, and lean meats supports healthy red blood cell production, while avoiding known triggers like certain medications or strenuous overexertion can reduce unnecessary red blood cell stress. Getting enough rest and managing underlying infections quickly also helps your body maintain healthy blood cells.

What's included in this test?

This test measures the amount of free hemoglobin present in your urine, which is a sign that red blood cells are breaking down somewhere in your body. Since hemoglobin normally stays inside red blood cells, finding it in urine helps flag conditions affecting red blood cell health.

What happens after I get my results?

Your results will show up in your account with a clear explanation of what a normal range looks like for free hemoglobin in urine. If your levels are elevated, next steps typically include retesting to confirm the finding, looking at recent activities or exposures that could cause red blood cell breakdown, and watching for symptoms like unusual tiredness or dark urine that may call for urgent care. You can download a standard lab report anytime, and the trends feature lets you track this marker over time if you test again in the future.

When will I get my results?

Results for this test are typically ready within about 7 days of your sample being processed at the lab. Once available, they'll be posted directly to your secure account, and you'll be able to view, download, and track them anytime.

Who should consider this test?

This test is a good fit for anyone noticing dark, tea-colored, or reddish urine without a clear cause. It's also useful if you've had a recent blood transfusion, suspect an autoimmune reaction affecting red blood cells, or have been diagnosed with a condition that causes red blood cell breakdown and want to monitor it over time.

What symptoms indicate I may need this test?

Common signs that may point to a need for this test include dark, red, or brown-colored urine, unusual fatigue, paleness, shortness of breath, or a rapid heartbeat. Some people also notice jaundice, which is a yellowing of the skin or eyes, alongside these symptoms.

What is free hemoglobin and why does it matter?

Free hemoglobin is the oxygen-carrying protein normally found inside red blood cells, but when those cells break apart, some of it spills into the bloodstream and can end up in urine. Finding it there matters because it often signals that red blood cells are being destroyed faster than the body can replace them, which can affect your energy levels and overall health if left unaddressed.

What does high free hemoglobin in urine mean?

A higher-than-normal result usually means red blood cells are breaking down somewhere in your body, a process called hemolysis. This can be triggered by things like infections, certain medications, autoimmune reactions, or complications from a blood transfusion, and it's worth retesting or seeking care if you also have symptoms like severe fatigue or dark urine.

How often should I retest?

If your first result comes back normal and you have no symptoms, retesting usually isn't necessary unless new symptoms appear. If you had an elevated result or an ongoing condition affecting red blood cells, retesting every few weeks to months can help you and track whether levels are improving or need closer attention.
