Explore the intricate balance of your thyroid function with our comprehensive analysis, covering essential biomarkers such as:
CRP HS
CRP (C-reactive protein) high-sensitivity (hs-CRP) measures very low levels of CRP in the blood. It is a marker of inflammation and is used to assess the risk of cardiovascular disease. Low hs-CRP levels are typically considered normal and indicate minimal systemic inflammation, suggesting a lower risk of heart disease. High hs-CRP levels suggest increased inflammation, which may indicate a higher risk of cardiovascular events such as heart attack or stroke. Elevated levels can also be associated with chronic conditions like diabetes, obesity, smoking, or infections and inflammatory diseases. Monitoring hs-CRP helps identify hidden cardiovascular risks and supports targeted interventions to reduce inflammation and improve heart health.
Ferritin
Ferritin is a protein that stores iron in the body and releases it as needed. Measuring ferritin levels provides an accurate assessment of the body’s iron stores and helps diagnose iron-related disorders. Low ferritin levels are a key indicator of iron deficiency, which can lead to anaemia. Causes include poor dietary intake, blood loss (e.g., heavy menstruation or gastrointestinal bleeding), or conditions that reduce iron absorption, such as coeliac disease or Crohn’s disease. High ferritin levels may indicate iron overload conditions such as haemochromatosis, repeated blood transfusions, or excessive iron supplementation. Elevated ferritin can also occur in inflammatory conditions, liver disease, or certain infections, as ferritin levels rise in response to inflammation. Monitoring ferritin levels is essential for evaluating iron stores and diagnosing both iron deficiency and overload, enabling targeted treatment.
Folate - Serum
Folate (serum) measures the level of folate, a B-vitamin essential for DNA production, red blood cell formation, and overall cell function. Folate is crucial for maintaining energy and preventing anaemia. Low folate levels may result in folate deficiency anaemia, causing fatigue, weakness, and shortness of breath. Common causes include poor dietary intake, malabsorption conditions like coeliac disease, increased demand during pregnancy, or chronic alcohol consumption. Certain medications, such as methotrexate, can also lower folate levels. High folate levels are typically not harmful and may result from excessive supplementation. However, it is important to address any underlying causes of deficiency if present. Monitoring serum folate is essential for diagnosing folate deficiency and ensuring optimal red blood cell production and overall health.
Vitamin B12 - Active
Active vitamin B12 measures the biologically available form of vitamin B12, which is essential for red blood cell production, nerve function, and DNA synthesis. It provides a more accurate reflection of functional B12 status compared to total B12 levels. Low active vitamin B12 levels may lead to deficiency, causing symptoms such as fatigue, weakness, numbness, memory issues, and, in severe cases, pernicious anaemia. Causes include inadequate dietary intake, malabsorption conditions like pernicious anaemia or Crohn’s disease, and certain medications that reduce B12 absorption, such as metformin or proton pump inhibitors. High active vitamin B12 levels are rare and typically not harmful. They may occur with supplementation or in some cases of liver disease or certain blood disorders. Monitoring active vitamin B12 helps diagnose deficiency and guides treatment to support nerve health, red blood cell production, and overall well-being.
Vitamin D
Vitamin D is a fat-soluble vitamin essential for bone health, immune function, and calcium absorption. It is primarily obtained through sunlight exposure and, to a lesser extent, from dietary sources and supplements. Low vitamin D levels can lead to deficiency, causing bone pain, muscle weakness, and an increased risk of fractures. Prolonged deficiency can result in conditions like rickets in children and osteomalacia in adults. Common causes include limited sunlight exposure, darker skin, malabsorption conditions, or inadequate dietary intake. High vitamin D levels are rare and typically result from excessive supplementation. Extremely high levels can lead to toxicity, causing symptoms like nausea, weakness, and hypercalcaemia (high blood calcium), which may damage the kidneys and other organs. Monitoring vitamin D levels is important for maintaining optimal bone health, supporting immune function, and preventing deficiency or toxicity.
TSH
TSH (thyroid-stimulating hormone) is a hormone produced by the pituitary gland that regulates the function of the thyroid gland. It helps control the production of thyroid hormones (T3 and T4), which are essential for metabolism, energy production, and overall hormonal balance. Low TSH levels may indicate hyperthyroidism (overactive thyroid), where excessive thyroid hormone production suppresses TSH. This can cause symptoms such as weight loss, increased heart rate, anxiety, and heat intolerance. High TSH levels may suggest hypothyroidism (underactive thyroid), where the thyroid gland does not produce enough hormones, prompting the pituitary to release more TSH. Symptoms can include fatigue, weight gain, cold sensitivity, and depression. High TSH can also occur in certain cases of pituitary dysfunction. Monitoring TSH levels is essential for diagnosing and managing thyroid conditions, ensuring proper metabolic function and hormonal balance.
Free T3
Free T3 (triiodothyronine) measures the active form of the thyroid hormone T3 that is not bound to proteins in the blood. It plays a critical role in regulating metabolism, energy production, and overall cellular function. Low free T3 levels may indicate hypothyroidism, where the thyroid gland is underactive and unable to produce sufficient hormones. This can lead to symptoms such as fatigue, weight gain, cold sensitivity, and sluggishness. Low levels can also occur due to severe illness (non-thyroidal illness syndrome) or nutritional deficiencies. High free T3 levels may indicate hyperthyroidism, where the thyroid gland is overactive. This can cause symptoms such as weight loss, rapid heartbeat, anxiety, sweating, and heat intolerance. High levels are often seen in conditions like Graves' disease or thyroid nodules. Monitoring free T3 levels is essential for assessing thyroid function and diagnosing thyroid imbalances that affect metabolic and overall health.
Free T4
Free thyroxine (free T4) measures the unbound, active form of the thyroid hormone T4 in the blood. T4 plays a key role in regulating metabolism, energy production, and growth. Low free T4 levels may indicate hypothyroidism, where the thyroid gland is underactive and fails to produce enough hormones. This can result in symptoms such as fatigue, weight gain, cold intolerance, dry skin, and depression. Low levels may also occur due to pituitary dysfunction or severe illness. High free T4 levels may indicate hyperthyroidism, where the thyroid gland is overactive. Symptoms can include weight loss, rapid heartbeat, anxiety, sweating, and heat intolerance. High levels are often associated with conditions such as Graves' disease or thyroid nodules. Monitoring free T4 levels is crucial for evaluating thyroid function and diagnosing disorders that affect metabolic and overall health.
Thyroglobulin Antibodies
Thyroglobulin antibodies (TgAb) are immune proteins produced when the immune system mistakenly targets thyroglobulin, a protein essential for thyroid hormone production. Measuring TgAb helps assess thyroid autoimmunity and monitor certain thyroid conditions. Low or undetectable thyroglobulin antibodies are normal and indicate no significant autoimmune activity affecting the thyroid. High TgAb levels may suggest an autoimmune thyroid disorder, such as Hashimoto’s thyroiditis or Graves’ disease. These conditions can lead to symptoms of hypothyroidism (fatigue, weight gain, cold sensitivity) or hyperthyroidism (weight loss, rapid heartbeat, heat intolerance). Elevated TgAb levels can also interfere with thyroglobulin measurements used to monitor thyroid cancer treatment. Monitoring TgAb levels is important for diagnosing autoimmune thyroid conditions, managing thyroid function, and evaluating response to thyroid cancer therapies.
Thyroid Peroxidase Antibodies
Thyroid peroxidase antibodies (TPOAb) are immune proteins produced when the immune system attacks thyroid peroxidase, an enzyme essential for thyroid hormone production. Measuring TPOAb levels helps identify autoimmune thyroid conditions. Low or undetectable TPOAb levels are normal and indicate no significant autoimmune activity affecting the thyroid. High TPOAb levels suggest the presence of an autoimmune thyroid disorder, such as Hashimoto’s thyroiditis or Graves’ disease. These conditions can cause hypothyroidism, with symptoms like fatigue, weight gain, and cold intolerance, or hyperthyroidism, with symptoms like weight loss, rapid heartbeat, and heat sensitivity. High TPOAb levels are also seen in some people with subclinical thyroid dysfunction or a family history of thyroid disease. Monitoring TPOAb levels is crucial for diagnosing autoimmune thyroid conditions, understanding thyroid function, and guiding treatment strategies.
