Ferritin is a blood protein that contains iron. A ferritin test helps your doctor understand how much iron your body stores. If a ferritin test reveals that your blood ferritin level is lower than normal, it indicates your bodys iron stores are low and you have iron deficiency. As a result, you could be anemic.
Vitamin D is essential for several reasons, including maintaining healthy bones and teeth. It may also protect against a range of diseases and conditions, such as type 1 diabetes.

Iron tests measure different substances in the blood to check iron levels in your body. Iron is a mineral thats essential for making red blood cells. Red blood cells carry oxygen from your lungs to the rest of your body. Iron is also important for healthy muscles, bone marrow, and organ function. Iron levels that are too low or too high can cause serious health problems.
A complete blood count (CBC) is a blood test used to evaluate your overall health and detect a wide range of disorders, including anemia, infection and leukemia.
A total iron-binding capacity (TIBC) test measures the bloods ability to attach itself to iron and transport it around the body. A transferrin test is similar. If you have iron deficiency (a lack of iron in your blood), your iron level will be low but your TIBC will be high. If you have too much iron (for example, if you have a condition like haemochromatosis), your iron level will be high but your TIBC will be low or normal.
