Biomarkers included – Fatigue Test

• Haemoglobin: Blood Health and Inflammation — Haemoglobin is a protein found in red blood cells responsible for carrying oxygen from the lungs to the rest of the body. Its level is a key indicator of a person's oxygen-carrying capacity and is crucial for diagnosing and monitoring conditions like anaemia, which is characterized by a deficiency in red blood cells or haemoglobin.
• Neutrophils: Blood Health and Inflammation — Neutrophils are a type of white blood cell and the most abundant type of phagocyte, a cell that engulfs and destroys foreign invaders like bacteria. Elevated neutrophil counts often indicate an acute infection or inflammatory response, making them a key indicator of the body's immediate defense mechanisms.
• Monocytes: Blood Health and Inflammation — Monocytes are a type of white blood cell produced in the bone marrow. These cells play a crucial role in the immune system by engulfing pathogens and cellular debris, and they differentiate into macrophages and dendritic cells to further combat infection and regulate immune responses.
• hs-CRP (high-sensitivity C-reactive protein): Blood Health and Inflammation — High-sensitivity C-reactive protein (hs-CRP) is a specific type of C-reactive protein test that can detect very low levels of inflammation in the body. While CRP is a general marker of inflammation, hs-CRP is particularly important for assessing the risk of cardiovascular disease, even in apparently healthy individuals. Elevated hs-CRP levels suggest chronic low-grade inflammation, which is a sign
• MPV: Blood Health and Inflammation — MPV, or Mean Platelet Volume, is a measure of the average size of platelets in a blood sample. Platelets are small blood cells that help with clotting, and their size can offer insights into how they are being produced and functioning. Both very small and very large platelets can be associated with certain medical conditions.
• MCV: Blood Health and Inflammation — MCV stands for Mean Corpuscular Volume. It measures the average size of red blood cells in a sample of blood. This biomarker is crucial for diagnosing and classifying different types of anemia, as it helps determine if red blood cells are smaller or larger than normal.
• White Blood Cells: Blood Health and Inflammation — The White Cell Count, also known as the leukocyte count, measures the total number of white blood cells (leukocytes) in a sample of blood. White blood cells are a crucial part of the immune system, helping to fight infections and diseases. An abnormal count can indicate infection, inflammation, allergic reactions, or other serious health conditions.
• MCHC: Blood Health and Inflammation — MCHC (Mean Corpuscular Hemoglobin Concentration) measures the average concentration of hemoglobin within a single red blood cell. It is a critical marker for diagnosing the cause of anemia, as it indicates whether red blood cells are carrying an appropriate amount of oxygen-binding protein relative to their size.
• RDW: Blood Health and Inflammation — RDW, or Red Blood Cell Distribution Width, is a measurement of the variation in size of your red blood cells. A higher RDW indicates that there is a significant difference in the sizes of your red blood cells, which can be an early indicator of various types of anemia and other underlying health conditions.
• Eosinophils: Blood Health and Inflammation — Eosinophils are a type of white blood cell that plays a role in the immune response, particularly against parasites and in allergic reactions. Elevated levels can indicate an infection, an allergic condition, or certain other diseases.
• MCH: Blood Health and Inflammation — MCH, or Mean Corpuscular Hemoglobin, measures the average amount of hemoglobin within a single red blood cell. Hemoglobin is crucial for carrying oxygen throughout the body, so MCH provides insight into the red blood cells' oxygen-carrying capacity and can help diagnose different types of anemia.
• Platelets: Blood Health and Inflammation — Platelets, also known as thrombocytes, are tiny, irregular-shaped cell fragments that play a crucial role in blood clotting. They circulate in the blood and, when an injury occurs, they aggregate at the site to form a plug, preventing excessive bleeding. Their count and function are vital for hemostasis and can indicate various health conditions.
• Red Blood Cells: Blood Health and Inflammation — The Red Cell Count, also known as the erythrocyte count, measures the number of red blood cells (erythrocytes) in a given volume of blood. These cells are crucial as they transport oxygen from the lungs to all tissues in the body and carry carbon dioxide back to the lungs for exhalation.
• Lymphocytes: Blood Health and Inflammation — Lymphocytes are a type of white blood cell and a crucial component of the immune system. They are responsible for recognizing and fighting off infections, as well as regulating the immune response, and are vital for adaptive immunity.
• HbA1c (Hemoglobin A1c): Blood Sugar and Metabolic Health — HbA1c (Hemoglobin A1c) measures the average blood glucose levels over the past 2-3 months by assessing the percentage of hemoglobin in red blood cells that is coated with sugar. It's a crucial indicator for diagnosing and monitoring diabetes, as persistently high levels denote poor long-term glucose control, increasing the risk of diabetes-related complications. This test provides a more stable an
• Transferrin Saturation: Iron Status — Transferrin saturation is a measure that reflects the percentage of transferrin — a blood protein that transports iron — that is actually bound to iron. It helps assess how effectively iron is being carried and utilized in the body. This marker is useful for identifying iron deficiency or iron overload, and is typically calculated using serum iron and total iron-binding capacity (TIBC). Low levels
• Total Iron Binding Capacity (TIBC): Iron Status — Total Iron Binding Capacity (TIBC) is a blood test that reflects the blood's capacity to bind and transport iron through transferrin — the main iron-carrying protein. It provides an indirect measure of available transferrin and is commonly used alongside other iron tests to help assess iron deficiency, anemia, or iron overload conditions.
• Iron: Iron Status — Iron is an essential mineral critical for oxygen transport, energy production, and cellular function throughout the body. It is a key component of hemoglobin in red blood cells and myoglobin in muscles, enabling oxygen delivery to tissues. Iron also plays vital roles in DNA synthesis, immune function, and cognitive development. Measuring iron levels helps diagnose anemia, assess nutritional status
• Unsaturated Iron Binding Capacity (UIBC): Iron Status — Unsaturated Iron Binding Capacity (UIBC) measures the amount of transferrin that is not saturated with iron, indicating the total amount of iron that could potentially be bound and transported in the blood. A high UIBC suggests the body needs more iron or is unable to properly utilize it, often seen in iron deficiency anemia.
• Ferritin: Iron Status — Ferritin is a protein that stores iron inside cells and serves as a key indicator of the body’s iron reserves. Measuring ferritin helps assess iron status: low ferritin is commonly associated with depleted iron stores and iron deficiency. Elevated ferritin can occur with iron overload, but it may also rise in response to inflammation, infection, liver disease, or other chronic conditions because f
• TSH: Thyroid Function — Thyroid-Stimulating Hormone (TSH), also known as thyrotropin, is a hormone produced by the pituitary gland. It plays a crucial role in regulating thyroid function by stimulating the thyroid gland to produce and release thyroid hormones (T3 and T4), which are vital for metabolism, growth, and development. Measuring TSH levels is a primary way to assess thyroid gland activity and diagnose thyroid di
• Free T4 (fT4): Thyroid Function — Free thyroxine (fT4) is the unbound fraction of the thyroid hormone T4 circulating in the blood. Because only the free hormone can enter cells, fT4 reflects the amount of thyroid hormone available to tissues and is a key marker of thyroid function. fT4 is commonly measured to help evaluate and monitor thyroid disorders—levels may be elevated in hyperthyroidism and reduced in hypothyroidism. It is
• Folate: Vitamin Status — Folate (vitamin B9) is a water-soluble vitamin essential for DNA synthesis, cell division, and normal red blood cell formation. It is especially important during pregnancy because adequate folate status supports early fetal development and helps reduce the risk of neural tube defects. Folate also participates in methylation pathways and homocysteine metabolism, where low folate can contribute to e
• Vitamin D: Vitamin Status — Vitamin D is a fat-soluble vitamin crucial for calcium absorption and bone health, playing a key role in phosphorus metabolism and immune system function. Its importance extends to muscle function, nerve signaling, and reducing inflammation. Maintaining adequate vitamin D levels is vital for overall well-being and disease prevention.
• Active B12: Vitamin Status — Active B12, also known as holotranscobalamin, is the specific portion of Vitamin B12 that is actually available for your cells to use. Unlike a standard total B12 test, measuring Active B12 provides a more accurate reflection of your functional vitamin status and can detect a deficiency at an earlier stage.
