What's this test for?

This test is ideal if you're experiencing persistent fatigue, weakness, pale skin, shortness of breath, or frequent headaches that you can't explain. It helps identify iron deficiency anemia, one of the most common causes of constant tiredness and low energy levels. Many people use this test when they suspect their exhaustion isn't just from stress or lack of sleep, but something more measurable in their blood.

What happens after I get my results?

You'll receive detailed doctor notes in simple language explaining what your iron levels, ferritin, and red blood cell counts mean for your energy and overall health. These notes include personalized recommendations like dietary changes to boost iron intake, supplement suggestions, or whether you should follow up with your doctor about underlying causes. Along with your standard lab report, you can track your iron levels over time using our trends feature to see how your diet or supplements are working.

What's included in this test?

This panel measures Iron (Total), Iron Binding Capacity, % Saturation, Ferritin, Reticulocyte Count (Automated and Absolute), and Complete Blood Count including Hemoglobin, Hematocrit, MCV, MCH, MCHC, RDW, White Blood Cell Count, Red Blood Cell Count, Platelet Count, and complete differential. This comprehensive panel measures your serum iron, iron binding capacity, ferritin (your body's iron storage), reticulocyte count (new red blood cells), and a complete blood count with hemoglobin and hematocrit. Together, these markers reveal whether you have enough iron in your blood, if your body is storing iron properly, and if your bone marrow is producing healthy red blood cells. This complete picture helps pinpoint whether iron deficiency is causing your fatigue and identifies how severe the anemia may be.

How should I prepare for this test?

You should fast overnight and have your blood drawn in the morning, as iron levels naturally decrease by 30% throughout the day. Avoid eating for at least 8 hours before your test to get the most accurate results. If you're taking high-dose biotin supplements (more than 5 mg per day), wait at least 8 hours after your last dose before testing, as biotin can interfere with certain measurements.

Who should consider getting this test?

This test is important for anyone experiencing unexplained fatigue, dizziness, or weakness that doesn't improve with rest. It's especially valuable for women with heavy menstrual periods, pregnant women, vegetarians or vegans, people with digestive conditions affecting nutrient absorption, and anyone who has been told they look pale or have noticed brittle nails or hair loss. Athletes and frequent blood donors should also consider testing regularly.

What symptoms indicate I may need this test?

Common symptoms include feeling tired all the time even after sleeping, weakness or difficulty exercising, pale or yellowish skin, shortness of breath with minimal activity, frequent headaches or dizziness, cold hands and feet, brittle nails, or unusual cravings for non-food items like ice or dirt. If you notice several of these symptoms together, it may indicate your body isn't getting enough oxygen due to low iron or red blood cells.

How can I naturally support my iron levels?

Boost your iron intake by eating red meat, poultry, fish, beans, lentils, spinach, and iron-fortified cereals. Pair iron-rich foods with vitamin C sources like oranges, strawberries, or bell peppers to enhance absorption. Avoid drinking tea or coffee with meals, as they can block iron absorption. Cooking in cast iron pans can also add small amounts of iron to your food.

What is ferritin and why does it matter?

Ferritin is a protein that stores iron in your body, acting like a reserve tank for when you need it. Low ferritin is often the first sign that your iron stores are depleting, even before you develop full anemia. Checking ferritin helps catch iron deficiency early, before it progresses to more serious symptoms like extreme fatigue and weakness.

What does low hemoglobin mean?

Low hemoglobin means your red blood cells aren't carrying enough oxygen throughout your body. Hemoglobin is the protein in red blood cells that binds to oxygen, and when it's low, your organs and tissues don't get the oxygen they need to function properly. This is what causes the fatigue, shortness of breath, and weakness associated with anemia.

How often should I retest my iron levels?

If you've been diagnosed with iron deficiency and started supplements or dietary changes, retest in 8-12 weeks to see if your levels are improving. Once your iron levels normalize, testing every 6-12 months is reasonable if you have ongoing risk factors like heavy periods or a restrictive diet. If your initial results are normal but symptoms continue, discuss retesting with your doctor in 3-6 months.
