TIBC Blood Test

Total Iron Binding Capacity Blood Test

The total iron binding capacity test is oftentimes referred to as a TIBC and measures the amount of iron in the bloodstream. It allows for physicians to determine if there is an excess or decreased iron value that might be causing disorders or other health concerns. The hormone transferrin is also measured because of its ability to carry iron throughout the body. The blood testing is generally used when individuals are suspected of having Anemia or other disorders that cause a decreased/increased level of iron.

Levels & Ranges Of The TIBC Blood Tests

Laboratory results can vary between labs and should be discussed with a professional, as there can be some differences. The normal iron level for adults is between 60 and 170 mcg/dL. The TIBC should range from 240 to 240 and 450 mcg/dL. Transferrin saturation is considered normal when between 20 and 50%. Those individuals that have a higher than normal level on their TIBC blood tests might suffer from iron deficiency anemia or late pregnancy. Lower than normal levels might suggest Cirrhosis, liver disease, Sickle cell anemia, malnutrition, hypoproteinemai or inflammation.

Conditions That Can Influence The Blood Test

There are certain conditions and that must be taken into consideration when reviewing the blood test levels. Medications such as fluorides and birth control medications can raise the TIBC levels. Medications that can lower the TIBC blood test level is ACTH and the medication Chloramphenicol. It is important to have regular blood tests to ensure that iron levels and other functions are within normal limits to ensure good health.
