About this Panel
Vitamins A, D, E and K are all fat-soluble and are collectively known as the 'Fat-soluble vitamins'. Any condition that causes the prolonged intestinal malabsorption of fat will also lead to a secondary deficiency of fat-soluble vitamins (e.g. biliary obstruction, celiac disease, pancreatic insufficiency, cystic fibrosis, Crohn's disease, etc.). Deficient states lead to the depletion of body stores and are eventually indicated by a decrease in the amount of the vitamin detected in your blood.
Vitamin A is required for vision, reproduction, growth and development, cellular differentiation and immune function. Deficiency leads to Night-blindness. Very high levels of vitamin A are toxic.
Vitamin D plays a critical role in regulating calcium and phosphorus levels in the body, which keep bones, teeth and muscles healthy. Additionally, it plays an important role in immune function, many chronic diseases and mental health. Specifically, it has been associated with cancer, cardiovascular disease and rickets in children and osteoporosis in adults.
Vitamin D is most commonly absorbed from exposure to the sun, although it can also be found in foods such as oily fish, red meat, liver and egg yolks. Vitamin D deficiency is common in the winter months when sun exposure is reduced.
Vitamin E is an antioxidant and plays an important part in maintaining the nervous system. A very high vitamin E intake can cause vitamin K deficiency.
Vitamin K plays an important role in blood coagulation, bone health and vascular health. For this test we measure and report serum vitamin K1 levels.
Who is this panel for?
The main role of your small intestine is to absorb nutrients from the food that you eat into your bloodstream. The nutrients are then transported by the blood to cells that rely on them to perform essential tasks. Any condition that prevents the optimal absorption of fat from your food may lead to deficiency in the fat-soluble vitamins (A, D, E and K). Prolonged deficiency of these vitamins has a wide ranging negative impact on your health if not recognised and corrected. Such conditions include celiac disease, Crohn’s disease, chronic pancreatitis or cystic fibrosis. The prolonged use of certain medications may also induce poor absorption – for example cholestramine and certain laxatives.
