What's this test for?

This test is ideal if you're experiencing constant fatigue, weakness, or feeling unusually tired throughout the day. It helps identify iron deficiency anemia, which is one of the most common causes of persistent tiredness and low energy. Many people use this test when they suspect their exhaustion might be related to low iron levels but want concrete answers.

What happens after I get my results?

You'll receive detailed doctor notes in simple language explaining what your iron levels mean for your energy and overall health. These notes include personalized recommendations like dietary changes to increase iron intake, supplement suggestions, or whether you should follow up with your doctor for further evaluation. You'll also get the standard lab report and can track your iron levels over time using our trends feature to see how your interventions are working.

What's included in this test?

This test measures % Saturation, Iron Binding Capacity (TIBC), and Iron, Total (serum iron). This panel evaluates your body's iron status by measuring serum iron, which shows how much iron is currently in your blood, total iron-binding capacity (TIBC), which indicates how well your blood can transport iron, and percent saturation, which reveals what portion of your iron-binding proteins are actually carrying iron. Together, these measurements help distinguish between iron deficiency anemia and other conditions that can cause low iron levels, giving you a complete picture of your iron health.

How should I prepare for this test?

You should fast for 8-12 hours before your test and schedule your blood draw in the morning if possible. Iron levels naturally decrease by about 30 percent during the day, so morning testing provides the most accurate baseline. Avoid eating fatty foods before your appointment, as they can interfere with the test accuracy.

Who should consider getting this test?

This test is important for people experiencing unexplained fatigue, weakness, pale skin, or shortness of breath. It's especially useful for women with heavy menstrual periods, pregnant women, frequent blood donors, vegetarians or vegans, and anyone with a history of anemia. People with inflammatory conditions or those monitoring iron storage diseases should also consider regular testing.

What symptoms indicate I may need this test?

Common symptoms include persistent tiredness even after sleeping, feeling weak or dizzy, pale skin or pale nail beds, and cold hands and feet. You might also notice brittle nails, unusual cravings for ice or non-food items, frequent headaches, or difficulty concentrating. If you experience shortness of breath during normal activities or have a rapid heartbeat, these can also indicate low iron levels.

How can I naturally increase my iron levels?

Focus on eating iron-rich foods like red meat, poultry, fish, beans, lentils, and dark leafy greens like spinach and kale. Pair these foods with vitamin C sources like citrus fruits, tomatoes, or bell peppers to boost iron absorption. Avoid drinking coffee or tea with meals as they can block iron absorption, and consider cooking with cast iron pans to add small amounts of iron to your food.

What is iron saturation and why does it matter?

Iron saturation, or percent saturation, measures what percentage of your transferrin (the protein that carries iron in your blood) is actually loaded with iron. It's calculated by dividing your serum iron by your TIBC. Low saturation typically indicates iron deficiency, while high saturation can suggest iron overload conditions. This measurement helps your doctor understand not just how much iron you have, but how effectively your body is using it.

What does low iron mean?

Low iron levels usually indicate iron deficiency anemia, which means your body doesn't have enough iron to make adequate red blood cells to carry oxygen throughout your body. This can result from not eating enough iron-rich foods, poor iron absorption, blood loss from heavy periods or internal bleeding, or increased iron needs during pregnancy. Low iron causes fatigue because your tissues aren't getting enough oxygen to function properly.

How often should I retest my iron levels?

If you're being treated for iron deficiency with supplements or dietary changes, retest every 2-3 months to monitor your progress until levels normalize. Once your iron is stable, annual testing is usually sufficient for monitoring unless you have ongoing risk factors like heavy periods or chronic conditions. If you're pregnant or have been diagnosed with an iron storage disorder, your doctor may recommend more frequent testing every 3-6 months.
