Ferritin

Insights Insights

Your ferritin levels are within the normal range, which is a positive result. Ferritin is a protein that stores iron in your body, and it is used as an indicator of your body's iron stores. Normal ferritin levels are important for healthy bodily functions, including the production of red blood cells. Maintaining normal ferritin levels is crucial to prevent iron deficiency or iron overload. Iron deficiency can lead to anemia, causing symptoms like fatigue, weakness, and difficulty concentrating. On the other hand, iron overload can lead to organ damage and other health problems. Since your ferritin levels are normal, it suggests that your body has an appropriate amount of iron stores. However, it's important to note that a blood test only provides a snapshot of your iron status at a specific point in time. Regular monitoring of your ferritin levels is recommended to ensure they remain within the normal range. If you have any concerns about your iron levels or overall health, it's always best to consult with your healthcare provider. They can evaluate your complete medical history and provide personalized advice based on your specific circumstances.

What's this test for?

This test is ideal if you're experiencing difficulty focusing, staying organized, or controlling impulses and want to understand if underlying health issues might be contributing. It helps identify vitamin and mineral deficiencies, thyroid problems, or other medical conditions that can worsen ADHD symptoms or interfere with treatment effectiveness. Many people use this test when they have an ADHD diagnosis and want to optimize their treatment, or when they're experiencing attention problems and want to rule out other causes.

How should I prepare for this test?

Fasting: 12 hours

You should fast for 12 hours before your blood draw, which means no food or beverages except water during that time. If you're taking high-dose biotin supplements (more than 5 mg per day), you should wait at least 8 hours after your last dose before testing. This fasting requirement ensures accurate measurements of your iron, glucose, and other key biomarkers.

What's included in this test?

Ferritin Lead (Venous) Magnesium Vitamin B12 Zinc

This comprehensive panel evaluates iron levels and storage (serum iron, TIBC, ferritin) that directly impact energy and cognitive function. It checks thyroid hormones (TSH, T4, T3) to identify metabolism issues affecting focus, measures essential vitamins and minerals (B12, Vitamin D, magnesium, zinc) critical for brain health, tests for lead exposure that can impair cognitive function, and includes a reticulocyte count to assess your body's ability to produce healthy red blood cells. Together, these measurements identify nutritional and medical factors that commonly worsen ADHD symptoms or interfere with treatment.

What happens after I get my results?
You'll receive detailed doctor notes in simple language explaining how your vitamin levels, thyroid function, and mineral status may be affecting your focus and attention. These notes include personalized recommendations like dietary changes, supplement suggestions, or whether you should follow up with your doctor about thyroid concerns or deficiencies. You'll also get the standard lab report and can track your levels over time using our trends feature to see how addressing deficiencies improves your symptoms.
When will I get my results?
You can expect to receive your results within 5 business days after your blood is collected. If any confirmatory testing is required for certain biomarkers, the turnaround time may be extended slightly, but you'll be notified if this is the case.
Who should consider getting this test?
This test is valuable for anyone with an existing ADHD diagnosis who wants to optimize their treatment outcomes, or for people experiencing focus and attention problems who want to rule out underlying medical causes. It's especially important if you're already on ADHD medication, as these drugs can affect your liver and kidneys, or if you have symptoms like fatigue, mood changes, and brain fog alongside attention difficulties.
What symptoms indicate I may need this test?
You might benefit from this test if you're experiencing persistent difficulty concentrating, staying organized, or controlling impulses, especially if accompanied by fatigue, mood swings, brain fog, or low energy. Symptoms like feeling cold all the time, unexplained weight changes, hair loss, or pale skin could indicate thyroid or iron deficiencies that worsen attention problems. If your ADHD treatment isn't working as well as expected, these underlying issues might be interfering with medication effectiveness.
How can I naturally support better focus and concentration?
Supporting brain health starts with ensuring adequate intake of iron-rich foods like red meat, leafy greens, and beans, along with B12 from animal products or fortified foods. Omega-3 fatty acids from fish, walnuts, and flax seeds support cognitive function, while regular exercise and consistent sleep schedules help regulate attention. Managing stress through mindfulness practices, staying hydrated, and limiting processed foods and sugar can also significantly improve focus and concentration.
What causes vitamin and mineral deficiencies that affect focus?
Deficiencies often result from poor diet, digestive issues that prevent proper nutrient absorption, or increased demands during stress or illness. Vegetarian or vegan diets may lack sufficient B12 and iron if not carefully planned, while digestive conditions like celiac disease or Crohn's can interfere with nutrient absorption. Chronic stress depletes magnesium stores, and limited sun exposure combined with indoor lifestyles commonly leads to vitamin D deficiency, all of which can impact cognitive function.
How often should I retest these levels?
If you're addressing deficiencies through diet changes or supplements, retesting in 8-12 weeks helps confirm your levels are improving. For those on ADHD medication, testing every 6-12 months monitors for any medication-related effects on your health markers. If your initial results are normal but symptoms persist, your doctor may recommend retesting in 3-6 months or exploring other factors affecting your attention and focus.
What should I do if my thyroid or iron levels are abnormal?
If your results show thyroid dysfunction or significant iron deficiency, schedule a follow-up with your primary care doctor or an endocrinologist to discuss treatment options. For mild deficiencies, start by incorporating more nutrient-rich foods into your diet and consider high-quality supplements after consulting with your healthcare provider. Continue monitoring your symptoms and retest in a few months to track improvements, as addressing these underlying issues often significantly enhances ADHD treatment effectiveness and overall focus.
