What's this test for?

This test is ideal if you're experiencing constant fatigue, weakness, pale skin, shortness of breath, or dizziness that won't go away. It helps identify the underlying cause of anemia by checking iron levels, vitamin B12, folate, and red blood cell health, along with a comprehensive metabolic panel to assess your overall health. Many people use this test when they suspect nutritional deficiencies or blood disorders are affecting their energy and daily functioning.

How should I prepare for this test?

Fasting: 12 hours
No biotin: 72 hours

You should fast for 12 hours before your blood draw and schedule your appointment in the morning, as iron levels naturally decrease by 30% throughout the day. Stop taking biotin supplements (vitamin B7 or B8) at least 72 hours before testing, as it can interfere with some test results. If you're taking methotrexate or leucovorin, consult with your doctor as these medications may affect folate test accuracy.

What's included in this test?

Ferritin Folate, Serum Vitamin B12

This comprehensive panel evaluates your iron status through serum iron, TIBC, and ferritin to identify iron deficiency anemia. It measures essential vitamins B12 and folate that are crucial for red blood cell production, and includes a complete blood count (CBC) to assess hemoglobin, hematocrit, and red blood cell characteristics. The reticulocyte count shows how actively your body is producing new blood cells, while the comprehensive metabolic panel checks kidney function, liver health, electrolytes, and blood sugar that can all impact your energy levels and overall wellness.

What happens after I get my results?
You'll receive detailed doctor notes in simple language explaining what your iron, vitamin, and red blood cell levels mean for your energy and overall health. These notes include personalized recommendations like dietary changes to boost iron and B vitamins, supplement suggestions, or whether you should follow up with your doctor about anemia treatment. You'll also get the standard lab report and can track your nutrient levels over time using our trends feature to see how your diet or supplementation is working.
When will I get my results?
Most results from this panel are typically available within 1-2 business days after your blood sample reaches the lab. You'll receive an email notification as soon as your results are ready to view in your secure online account. Some individual tests in this comprehensive panel may be available sooner than others.
Who should consider getting this test?
This test is essential for anyone experiencing persistent fatigue, weakness, or shortness of breath that interferes with daily activities. It's particularly important for women with heavy menstrual periods, pregnant women, vegetarians or vegans at risk for B12 deficiency, people with digestive disorders that affect nutrient absorption, and anyone who has been told they look pale or have symptoms of anemia. Those with a family history of blood disorders should also consider this comprehensive screening.
What symptoms indicate I may need this test?
Common signs include constant tiredness that doesn't improve with rest, weakness, pale or yellowish skin, irregular heartbeat, dizziness or lightheadedness, cold hands and feet, and headaches. You may also experience shortness of breath during normal activities, brittle nails, cravings for ice or non-food items, or a sore or swollen tongue. These symptoms can develop gradually and may be dismissed as stress or lack of sleep, but they often indicate an underlying nutritional deficiency or blood disorder.
How can I naturally support healthy iron and blood levels?
Focus on eating iron-rich foods like red meat, poultry, fish, beans, lentils, and dark leafy greens, and pair them with vitamin C sources like citrus fruits or bell peppers to enhance absorption. Include foods high in vitamin B12 (meat, fish, dairy, eggs) and folate (leafy greens, legumes, fortified cereals) to support red blood cell production. Cook with cast iron pans to add extra iron to your meals, and avoid drinking tea or coffee with meals as they can inhibit iron absorption.
What is ferritin and why does it matter?
Ferritin is a protein that stores iron in your body and serves as the best indicator of your total iron reserves. Low ferritin levels mean your iron stores are depleted, even if your current blood iron levels appear normal, and this is often the first sign of developing iron deficiency anemia. Monitoring ferritin helps catch iron deficiency early before it progresses to full anemia, and it's especially important for women of childbearing age, athletes, and frequent blood donors.
What does low hemoglobin mean?
Low hemoglobin means your red blood cells aren't carrying enough oxygen throughout your body, which is the definition of anemia. This explains why you might feel constantly tired, weak, or short of breath, as your organs and tissues aren't getting the oxygen they need to function properly. Low hemoglobin can result from iron deficiency, vitamin B12 or folate deficiency, chronic diseases, or blood loss, and this panel helps identify which specific cause is affecting you.
How often should I retest my iron and vitamin levels?
If you've been diagnosed with anemia or deficiencies and started treatment, retest in 8-12 weeks to see if your iron supplementation or dietary changes are working. Once your levels normalize, annual testing is recommended to ensure they stay stable, especially if you have risk factors like heavy periods or dietary restrictions. If you're pregnant or have chronic conditions affecting nutrient absorption, your doctor may recommend more frequent monitoring every 3-6 months.

Your testosterone levels are slightly below the optimal range. While this is not necessarily cause for concern, it may contribute to occasional fatigue, reduced motivation, or lower muscle mass over time.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More complex tests, such as hormone panels, may take up to 10–15 business days due to their complexity.
