To check your thyroid, you need a simple blood test that measures key hormones like TSH, T4, and T3. At mylabpanel.com, we offer convenient at-home thyroid panels that let you monitor your thyroid health from the privacy of your home. Today, thyroid testing remains the gold standard for diagnosing conditions like hypothyroidism and hyperthyroidism, and our easy-to-use kits provide accurate, lab-certified results without a doctor visit.
Thyroid function tests evaluate how well your thyroid gland is producing and regulating hormones. The primary markers include TSH (thyroid-stimulating hormone), Free T4, Free T3, and sometimes thyroid antibodies. Each marker tells a different part of the story.
Preparation ensures accurate results. Most thyroid tests do not require fasting, but certain medications (like biotin, thyroid hormones, or birth control) can interfere. Always inform your healthcare provider about any supplements or prescriptions.
For optimal accuracy, take your test in the morning when TSH levels are highest. Avoid taking your thyroid medication until after the blood draw unless your doctor advises otherwise. Our at-home kit instructions include detailed preparation steps.
Reference ranges can vary slightly by lab, but here are typical values used today:
| Marker | Normal Range | Indication |
|---|---|---|
| TSH | 0.4–4.0 mIU/L | High = hypothyroidism; Low = hyperthyroidism |
| Free T4 | 0.8–1.8 ng/dL | Low = hypothyroidism; High = hyperthyroidism |
| Free T3 | 2.3–4.2 pg/mL | Low = hypothyroidism; High = hyperthyroidism |
Note: These ranges are general guidelines. Your doctor will interpret results based on your symptoms and medical history. If you test borderline, additional antibody testing may be recommended.
You should check your thyroid if you experience fatigue, weight changes, temperature sensitivity, hair loss, mood swings, or irregular heartbeat. Family history of thyroid disease, pregnancy, or autoimmune conditions also increase your risk. Routine screening is advised for women over 35 and anyone with unexplained symptoms.

Fasting is not usually required, but avoid biotin supplements and take your test in the morning for most accurate TSH levels.
High TSH typically indicates an underactive thyroid (hypothyroidism). Your thyroid is not producing enough hormones, so the pituitary gland releases more TSH to stimulate it.
