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.

Questassured(TM) 25 Hydroxyvitamin D(D2,D3)
Insights
Your levels of Vitamin D, specifically 25-hydroxyvitamin D (D2 and D3), appear to be within the normal range. This is good news, as Vitamin D plays a crucial role in maintaining healthy bones and immune function.
Research shows that maintaining appropriate levels of Vitamin D is important for overall health. It's recommended that you continue to engage in activities that promote Vitamin D synthesis, such as spending time in the sunlight or consuming foods rich in this vitamin. However, it's always a good idea to discuss your specific health needs with your healthcare provider.
If you have any concerns about your Vitamin D levels or any other aspect of your blood test, I encourage you to reach out to your healthcare provider for further discussion and guidance. They will have a comprehensive understanding of your medical history and can provide personalized recommendations to support your overall well-being.

diet or supplementation. Therapy is based on
measurement of Total 25-OHD, with levels <20 ng/mL
indicative of Vitamin D deficiency, while levels
between 20 ng/mL and 30 ng/mL suggest insufficiency.

This test is ideal if you're experiencing unexplained fatigue, weight changes, difficulty losing weight, mood swings, hair loss, or feeling cold all the time. It helps identify thyroid disorders and checks whether nutritional deficiencies in iron or vitamin D might be contributing to your symptoms. Many people use this test when they suspect their persistent tiredness and metabolic issues are related to thyroid function or nutrient deficiencies but want concrete answers.
How should I prepare for this test?
Fasting is preferred but not required for this test. If you're taking high-dose biotin supplements (more than 5 mg per day), you should wait at least eight hours after your last dose before having blood drawn, as biotin can interfere with test accuracy. Otherwise, you can take your regular medications and supplements as prescribed.
This comprehensive panel evaluates your complete thyroid function through TSH, Free T3, and Free T4 to identify causes of fatigue, weight changes, and temperature sensitivity. It checks for autoimmune thyroid conditions with antibody tests (TPO and Thyroglobulin), measures ferritin to assess iron stores that affect energy and hair health, and evaluates vitamin D levels which impact mood, bone health, and immune function. Together, these measurements provide a complete picture of thyroid health and the key nutrients that support it.
What happens after I get my results?
You'll receive detailed doctor notes in simple language explaining what your thyroid levels mean for your energy, metabolism, and overall health. These notes include personalized recommendations like dietary changes, supplement suggestions for vitamin D or iron deficiencies, and whether you should consider follow-up with an endocrinologist. You'll also get the standard lab report and can track your thyroid and nutrient levels over time using our trends feature to see how your interventions are working.
When will I get my results?
You can expect your results within approximately 5 business days after your blood is drawn. In some cases, if confirmation testing is needed for any of the markers, the turnaround time may be extended by a few additional days. You'll receive an email notification as soon as your results are ready to view.
Who should consider getting this test?
This test is ideal for people experiencing unexplained fatigue, weight gain or difficulty losing weight, mood changes, or feeling cold frequently. It's especially important for women with irregular periods, those with a family history of thyroid disease, anyone experiencing hair loss or dry skin, and people who suspect they have low iron or vitamin D. It's also valuable for those already being treated for thyroid conditions who want to monitor their levels alongside nutritional markers.
What symptoms indicate I may need this test?
Common symptoms include persistent fatigue even after adequate sleep, unexplained weight gain or difficulty losing weight despite diet and exercise, feeling cold when others are comfortable, and mood changes like depression or anxiety. You might also notice hair thinning or loss, dry skin, constipation, muscle weakness, brain fog, or irregular menstrual periods. These symptoms can overlap between thyroid dysfunction and vitamin D or iron deficiencies, which is why this comprehensive panel is so helpful.
How can I naturally support my thyroid function?
Supporting thyroid health starts with ensuring adequate iodine and selenium intake through foods like fish, eggs, Brazil nuts, and dairy products. Getting enough quality sleep (7-8 hours), managing stress through meditation or yoga, and exercising regularly can help balance thyroid hormones. Ensure adequate vitamin D through sunlight exposure and diet, and include iron-rich foods like lean meat, spinach, and lentils. Limiting processed foods, avoiding excessive soy products, and reducing exposure to environmental toxins may also help.
What is TSH and why does it matter?
TSH (Thyroid Stimulating Hormone) is produced by your pituitary gland and tells your thyroid how much hormone to make. It's the most important screening test for thyroid problems because it shows whether your thyroid is underactive or overactive. When TSH is high, it usually means your thyroid isn't making enough hormone (hypothyroidism), causing fatigue and weight gain. When TSH is low, your thyroid may be overactive (hyperthyroidism), causing anxiety and weight loss.
What does high TSH mean?
High TSH typically indicates hypothyroidism, meaning your thyroid gland isn't producing enough thyroid hormone, so your pituitary is working harder to stimulate it. This can cause fatigue, weight gain, feeling cold, constipation, dry skin, and depression. Causes include autoimmune conditions like Hashimoto's thyroiditis, iodine deficiency, or thyroid damage. Your doctor may recommend thyroid hormone replacement medication if levels are significantly elevated.
How often should I retest my thyroid levels?
If you're starting or adjusting thyroid medication, retest every 6-8 weeks until your levels stabilize in the optimal range. Once stable on medication, testing every 6-12 months is typically recommended for ongoing monitoring. If you're testing for the first time with normal results but persistent symptoms, consider retesting in 3-6 months. For monitoring vitamin D and ferritin alongside thyroid function, retesting every 3-6 months helps track your progress with supplementation or lifestyle changes.
