The Thyroid Function Blood Test evaluates thyroid health by measuring key hormones and antibodies, including TSH, Free T4, Free T3, and Anti TPO. It aids in diagnosing thyroid disorders and monitoring treatments.
Customize TestThyroid Function Blood Test provides a thorough evaluation of your thyroid gland by analysing key hormones and antibodies that control metabolism, energy, growth, and overall wellbeing. The thyroid plays an essential role in nearly every system of the body, and even small imbalances can have a significant impact on how you feel. This test is designed to give you a detailed understanding of your thyroid function and help you identify potential issues early.
Youth Revisited offers flexible testing options including a home testing kit, a phlebotomist home visit, or a clinic blood draw. With fast results and clear explanations, you receive everything you need to understand your thyroid health confidently.
This test checks several important thyroid markers, starting with TSH (thyroid-stimulating hormone), also called thyrotropin stimulating hormone, which regulates the production of thyroid hormones. TSH is a key indicator because changes in this hormone often appear before shifts in T3 or T4.
The test also measures Free T4, Free T3, Total T4, Total T3, and thyroid antibodies such as Anti-TPO and Anti-TG. In some cases, Reverse T3 and Thyroglobulin are included to provide a deeper assessment. Together, these markers help identify patterns such as low t4 and normal tsh, elevated tsh and normal t4, which can help uncover early thyroid imbalances.
These values also help explain the function of thyroid gland hormones, including how T3 and T4 influence metabolism, weight, hair growth, energy production, and temperature regulation. When thyroid hormones fall outside the normal range, your body may react through fatigue, weight changes, heart rhythm changes, or skin and hair issues.
This test is ideal for individuals who experience symptoms such as tiredness, weight gain or loss, cold intolerance, hair thinning, palpitations, and mood changes. These signs may relate to low levels of thyroid hormones, autoimmune activity, or early metabolic imbalance.
People with a family history of thyroid disease, those living with autoimmune conditions, and individuals already diagnosed with hypothyroidism or hyperthyroidism can benefit from routine monitoring. Understanding normal tsh levels in females, normal tsh levels by age, and the tsh reference range by age is especially helpful because TSH can naturally change over time.
This test also supports those experiencing the symptoms of increased tsh level, such as fatigue, dry skin, and slower metabolism. Women may especially benefit from thyroid testing because hormonal changes can influence thyroid activity, and understanding the causes of high tsh in females helps explain why symptoms sometimes appear suddenly.
Pregnant individuals can also benefit from thyroid monitoring, as thyroid levels can change significantly during pregnancy. Knowing the tsh level during pregnancy and how it relates to overall health supports better outcomes for both mother and baby.
Your thyroid report provides clear explanations for each marker. If your results show serum tsh level abnormal, your clinician may discuss possible reasons or recommend additional investigations.
Patterns such as elevated tsh and normal t4 may indicate early hypothyroidism, while low t4 and normal tsh may suggest different types of thyroid dysfunction. Identifying trends early allows you to take action before symptoms progress.
Some individuals may also experience high t4 and high tsh, which can occur in rare conditions or due to medication effects. Reviewing your full results helps understand what is happening and how your thyroid may be responding.
Your test report will also compare your values against normal tsh levels by age and the established laboratory ranges for each hormone. These comparisons provide clarity about whether your thyroid is functioning within expected levels for your age and health profile.
Thyroid imbalance can affect energy, mood, metabolism, temperature, skin health, digestion, fertility, and cognitive function. Even mild abnormalities can influence how you feel each day. Thyroid testing helps you identify and manage these changes early.
Some people may have subtle symptoms but normal basic tests; however, a more detailed panel helps reveal underlying patterns. Monitoring thyroid antibodies can detect autoimmune thyroid disease such as Hashimoto’s or Graves’ disease before major symptoms appear.
Understanding your hormone levels also helps explain why your metabolism may feel slower, why hair thinning may occur, or why weight changes become difficult to manage. Identifying low levels of thyroid hormones early supports more effective treatment.
After you receive your results, you can review the explanations provided in your report. If abnormalities are present such as high TSH, low T4, or elevated antibodies consulting a healthcare professional is recommended. Early intervention improves long-term thyroid health and may reduce symptoms significantly.

TSH measures how well the pituitary gland stimulates the thyroid. High levels can indicate hypothyroidism, while low levels may suggest hyperthyroidism, affecting metabolic functions.
T4 measures the amount of unbound T4 available for use by the body. Abnormal levels can help diagnose conditions like hypothyroidism or hyperthyroidism by assessing thyroid hormone availability.
T3 evaluates the active form of thyroid hormone circulating in the blood. It’s important for diagnosing hyperthyroidism when TSH is suppressed, but T4 levels are normal, indicating thyroid dysfunction.
Anti-TPO and Anti-TG are antibodies tested to detect autoimmune thyroid conditions like Hashimoto’s thyroiditis and Graves’ disease. Elevated levels help diagnose and monitor these conditions.
Thyroglobulin is primarily used as a tumor marker in thyroid cancer patients. It helps monitor the effectiveness of treatment or track potential recurrence of thyroid cancer after treatment.
