Vitamins
Vitamin D
Vitamin D is a hormone that is primarily synthesized in the skin upon exposure to sunlight. It is important for maintaining bone health as it aids in calcium absorption from the intestines. Apart from this, vitamin D also plays a role in immune function and is associated with various chronic diseases and mental health. In the UK, many people have low levels of vitamin D, which can cause symptoms such as muscle weakness, fatigue, and mood swings. People with dark skin and those who do not spend much time outdoors are particularly at risk of low vitamin D levels. Vitamin D can also be obtained from food, especially oily fish, eggs, and fortified foods. However, food sources may not be sufficient to correct a deficiency in vitamin D.

Thyroid hormones
TSH
Thyroid stimulating hormone (TSH) is a hormone produced by the pituitary gland that regulates the production of thyroid hormones thyroxine (T4) and triiodothyronine (T3) by the thyroid gland. TSH levels increase when thyroid hormone levels are low, and decrease when thyroid hormone levels are high. Abnormal TSH levels can indicate problems with the thyroid gland, such as under or overproduction of thyroid hormones. It can also be a result of pituitary gland disorders.
Free thyroxine
Thyroxine (T4) is one of the two primary hormones produced by the thyroid gland. It plays a vital role in regulating metabolic processes in the body. T4 is mostly bound to carrier proteins in the blood, and only a small amount of it exists in its free or unbound form. In contrast to free T3, free T4 is relatively inactive, but it is still essential for normal body function. When the body requires thyroid hormone, free T4 is converted to the more active form, free T3.
Iron profile
Iron
Iron is a mineral that is necessary for the body to function properly. It is an essential component of haemoglobin, a protein present in red blood cells that transports oxygen throughout the body. Insufficient iron in the body can lead to a decrease in haemoglobin levels and result in symptoms such as fatigue, dizziness, and shortness of breath. However, measuring serum iron alone may not provide an accurate picture of iron levels as it can be influenced by the recent intake of iron-rich foods. Therefore, iron is typically evaluated alongside other markers in an iron status test.

Ensure that any symptoms of short-term illness have subsided before taking this test. To obtain accurate results, it is important to refrain from taking any medication or vitamin/mineral supplements prior to the test. Additionally, avoid the use of biotin supplements for at least two days before the test, and consult with your doctor if you have been prescribed biotin.
