23 Biomarkers
Liver health
Liver tests, frequently known as liver function tests (LFTs), are a group of blood tests that help assess the health of your liver. These tests measure the levels of various enzymes, proteins, and substances produced or excreted by the liver. Abnormal results in these tests can indicate liver disease or dysfunction, which can significantly influence energy levels.
Alkaline Phosphatase (ALP)
Measuring alkaline phosphatase (ALP) is useful when assessing both liver and bone health. Measuring alkaline phosphatase (ALP) levels can help identify causes of fatigue by providing insights into specific conditions affecting the liver, bile ducts, or bones, all of which can influence energy levels.
Alanine Aminotranserase (ALT)
Alanine aminotransferase (ALT) is an enzyme primarily found in the liver. Only small amounts are usually found in the blood. However, if the liver or muscles are damaged an increased level of ALT will be released into the bloodstream. Elevated ALT levels can be caused by alcohol, fatty liver, viruses, or intense exercise.
Gamma GT (GGT)
Gamma-glutamyl transferase (GGT) is an enzyme found mainly in the liver. The concentration of GGT within the bloodstream increases when there is either damage to the liver or bile ducts, or when there is increased production of GGT within the liver. This can occur due to taking many medications, smoking, poorly controlled diabetes and excessive alcohol consumption.
Total Protein
Total protein is the combination of both albumin and globulin levels. Proteins play a vital role in the development of the body's cells and tissues and are essential for muscle repair, immune function, and overall health. Testing total protein levels aids in detecting nutritional deficiencies and assessing liver function.
Albumin
Albumin, a protein produced by the liver, plays several crucial roles in health: maintaining blood volume and pressure, transporting hormones, vitamins, and medications, and supplying essential amino acids for tissue growth and repair. Low albumin levels can signal inadequate protein intake or absorption, kidney or liver damage, and chronic inflammation.
Globulin (calculated)
Globulins are proteins produced by the liver and immune system. High or low levels can impair the body's ability to fight infection, clot or carry nutrients to the muscles. Abnormal levels can indicate liver dysfunction, inflammation, or damage as well as liver chronic diseases such as cirrhosis or hepatitis.
Vitamins
Vitamins are essential nutrients obtained from food and sunlight. They support vital functions like bone health, energy production and fighting infection. Deficiencies can lead to various health issues, including bone disorders, anaemia, low mood and fatigue.
Active B12
Active B12 measures forms of B12 which are available for direct use by the body. This is a more accurate measure of health than total B12. This vital vitamin has an important role in red blood cell production and helps prevent anaemia. It helps to boost energy, improve mood, and enhances cognitive function.
Folate (serum)
Folate, or vitamin B9, is essential for DNA repair, cell growth, and producing red blood cells, preventing anaemia and boosting your energy. Women, especially those of childbearing age, have higher folate requirements compared to men. Adequate folate intake ensures optimal cellular function and energy production, helping to reduce tiredness.
Vitamin D (25 OH)
Vitamin D is essential for healthy bones, immune function, muscle performance, energy, mood and reducing inflammation. It's primarily produced through sunlight exposure so people in the UK are more prone to deficiency than warmer countries. Vitamin D deficiency can lead to fatigue, depression, bone injuries, musculoskeletal pain, and increased viral infections.
Minerals
Minerals support bone strength, muscle function, nerve signalling, and energy production. They regulate vital processes such as blood pressure and immune responses. Key minerals like calcium, magnesium, and iron are obtained through diet and are crucial for preventing deficiencies and maintaining overall health.
Ferritin
A ferritin test measures the total level of iron stored in your body. Iron is crucial for energy production, immune function, cognitive health and muscle performance. Low levels can cause fatigue, weakness, low mood and lead to iron-deficiency anaemia. Women are more prone to low ferritin than men due to blood loss during the menstrual cycle.
Magnesium
Magnesium is a vital trace element essential for maintaining strong bones, regulating blood pressure, facilitating muscle contraction, and producing energy. Since the primary source of magnesium is through diet, testing your magnesium levels can identify deficiencies and help you make necessary dietary adjustments for optimal health.
Full Blood Count
A Full Blood Count (FBC) test measures various components of blood. In this test it includes red and white blood cell count together with haemoglobin. These tests helps identify conditions like anaemia, a common cause of fatigue, where the blood lacks enough healthy red blood cells to carry adequate oxygen to the body's tissues.
Red Blood Cells (RBC)
An RBC test measures the number of red blood cells in your blood. Red blood cells are an important transporter of oxygen, taking it from the lungs to cells around the body. Low RBC is often an indication of anaemia which can be due to a number or causes including nutrition deficiency.
White Blood Cells (WBC)
White blood cell count (WBC) measures the total number of white blood cells in a volume of blood. White blood cells are crucial for fighting infections and are a key part of the immune response. A low WBC can increase susceptibility to viral, bacterial, and fungal infections.
Haemoglobin
Haemoglobin, found in red blood cells, carries oxygen throughout the body, enabling cellular respiration and energy production. Low haemoglobin levels can indicate anaemia, leading to reduced energy. By improving your haemoglobin you can improve your organ and tissue functions and increase your overall energy levels.
Haemoglobin A1c (HbA1c)
HbA1c provides an average reading of blood sugar levels over a period of 2-3 months. It is considered one of the best indicators of pre-diabetes. While HbA1c itself is not directly involved in energy production, it provides critical information about blood glucose control, which is closely linked to energy metabolism.
Kidney function
Kidney function tests assess how well the kidneys filter waste and balance fluids and electrolytes. Impaired kidney function can lead to toxin build-up, electrolyte imbalances, and anaemia, all of which can contribute to fatigue and reduced energy levels.
Urea
Both urea and creatinine are good indicators of whether the kidneys are working properly. Urea is a waste product formed in the liver when protein is metabolised. It is released into the bloodstream and carried to the kidneys where it is expelled within urine. If the kidneys are not performing correctly the level of urea will rise.
Uric Acid
Uric acid or urate is a natural waste product produced when the body breaks down purines. Most uric acid is removed from the body by the kidneys. Too much uric acid can lead to the formation of solid crystals in the joints - known as gout. High levels can also lead to the formation of kidney stones.
Creatinine
Creatinine is a waste product which is produced by muscles when they break down creatine. It is excreted from the body by our kidneys in urine. Therefore, the levels of creatinine can give a good indication of how effectively the kidneys are working. Elevated levels suggest potential kidney stress or increased muscle metabolism.
eGFR
Estimated glomerular filtration rate (eGFR) measures how well the kidneys filter waste from the blood. It helps detect kidney disease early and can provide an overall assessment of kidney function. The calculation is based on levels of creatinine and results can be influenced by a number of factors including muscle mass, weight and hydration.
Thryoid Function
Thyroid hormones help to control the rate at which your body converts food into energy. Thyroid imbalance can lead to problems with weight, energy and mood.
Thyroid Stimulating Hormone (TSH)
Thyroid-stimulating hormone (TSH) regulates thyroid function by stimulating the production of thyroid hormones T3 and T4, which control metabolism and energy production. Women are more likely to develop thyroid disorders than men. Abnormal thyroid levels impact weight, energy levels, mood, menstrual cycle and can cause erectile dysfunction in men.
Thyroxine (T4, free direct)
A thyroxine (T4) test is used to check that the thyroid is performing properly. An overactive thyroid can cause too much thyroxine to be released whilst an underactive thyroid can lead to too little. Abnormal levels can impact weight, energy, and mood.
Triiodothyronine (T3, free)
Triiodothyronine (T3) is the active form of thyroxine (T4). High T3 levels may indicate hyperthyroidism, with symptoms such as fatigue, weight loss, irritability, and increased heart rate. Low T3 levels can suggest hypothyroidism, causing fatigue, weight gain, and muscle stiffness. Free T3 measures the free or unbound levels of T3.
Cortisol
Cortisol, a hormone released during stress, regulates metabolism and immune response. Chronic high cortisol levels can disrupt sleep, increase blood sugar, and deplete energy reserves, contributing to persistent fatigue.
If you’re wanting a more comprehensive analysis to help identify the cause of low energy, then this test is for you. It checks key nutrients such as vitamin D, B12, folate and ferritin along with cortisol (stress), magnesium, and hs-CRP (inflammation). To rule out conditions that could be causing your symptoms this test also checks HbA1c (pre-diabetes) along with thyroid, liver and kidney function along with immune health.
"This test incorporates 24 markers that includes all the 'usual suspects' when we are looking to identify why someone is fatigued or not performing their best. Identifying nutritional deficiencies, hormonal imbalances and metabolic dysfunction means being able to take positive steps to address the root cause and boost your energy levels. "
