What's tested?

Vitamin D

The main source of vitamin D is sunlight, but in the UK we can't make any vitamin D from winter daylight between November and March and so Vitamin D deficiency is common in men and women of all ages. For others, the kidneys have trouble converting the nutrient to its active form or their being overweight makes vitamin D less available for use in the body.

  • 25-hydroxy Vitamin D

Thyroid Function

The thyroid is a gland found in the neck. It produces hormones that are released into the bloodstream to control the body's growth and metabolism. An overactive or underactive thyroid leads to hormone imbalances which can cause symptoms such as tiredness, weight gain and feeling depressed.

  • Thyroid Stimulating Hormone (TSH)
  • Free Thyroxine (FT4)

Iron Levels

Iron is used to produce red blood cells, which help store and carry oxygen in the blood. If you have fewer red blood cells than is normal, your organs and tissues won't get as much oxygen as they usually would. This can lead to what is know as Iron deficiency anaemia which can cause fatigue, shortness of breath, dizziness, headache, coldness in your hands and feet, pale skin, and chest pain. Treatment for iron deficiency anaemia usually involves taking iron supplements and changing your diet to increase your iron levels.

  • T.I.B.C.
  • Transferrin Saturation
  • Ferritin
  • Iron
