Total Iron Binding Capacity equals the Unsaturated Iron Binding Capacity plus serum iron: TIBC = UIBC + Serum Iron.
What is a normal TIBC level?
Normal Results
Normal value range is: Iron: 60 to 170 micrograms per deciliter (mcg/dL) or 10.74 to 30.43 micromoles per liter (micromol/L) TIBC: 240 to 450 mcg/dL or 42.96 to 80.55 micromol/L.
What does high calculated TIBC mean?
High TIBC means that you have low levels of iron. When there isn’t much iron to attach to, you’ll have a lot of free transferrin in your blood. Low iron levels can lead to iron deficiency anemia, a condition in which your body doesn’t have enough iron to make healthy red blood cells.
What causes high TIBC?
Causes of high iron levels
A TIBC test may be ordered if your doctor suspects you have too much iron in your blood. High levels of iron most commonly indicate an underlying medical condition. In rare cases, high iron levels may be caused by an overdose of vitamins or iron supplements.
What is the difference between UIBC and TIBC?
Because of this, your blood serum has considerable extra iron-binding capacity, which is the Unsaturated Iron Binding Capacity (UIBC). The TIBC is the total iron-binding capacity; it equals UIBC plus the serum iron measurement. Some laboratories measure UIBC, some measure TIBC, and some measure transferrin.
How is UIBC measured?
The unsaturated iron-binding capacity (UIBC) is measured using radioactive iron or spectrophotometric approaches. The sum of the UIBC and the plasma iron is the total iron-binding capacity (TIBC). Direct measurement of the TIBC may also be performed. The iron-binding capacity reference range is 255-450 μg/dL.
What iron level is anemic?
Lower than normal hemoglobin levels indicate anemia. The normal hemoglobin range is generally defined as 13.2 to 16.6 grams (g) of hemoglobin per deciliter (dL) of blood for men and 11.6 to 15 g/dL for women.
How do you read iron test results?
Abnormal ranges
A score below 26 mcg/dL is outside the normal range for women. For men, a low score is anything below 76 mcg/dL. An abnormally high iron level would be above 198 mcg/dL for men and over 170 mcg/dL for women.
What does low TIBC and high ferritin mean?
Total iron binding capacity
High levels of TIBC indicate a low amount of iron “filling seats” on the bus. This is one way to tell if ferritin levels are elevated due to inflammation—a normal or high ferritin level coupled with high TIBC indicates inadequate intake of iron.
Why does iron deficiency cause TIBC?
In iron-deficient conditions, the relative transferrin content compared to iron content increases, and thus the TIBC values are high. The opposite happens in iron overloaded states of the body; the quantity of free transferrin in blood decreases, and consequently, TIBC values are low.
What causes iron deficiency?
Slow, chronic blood loss within the body — such as from a peptic ulcer, a hiatal hernia, a colon polyp or colorectal cancer — can cause iron deficiency anemia. Gastrointestinal bleeding can result from regular use of some over-the-counter pain relievers, especially aspirin. A lack of iron in your diet.
How is low iron binding capacity treated?
A medical professional will diagnose low iron saturation using a combination of tests, which may include a complete blood count, a serum iron test, a transferrin test, and a TIBC test. The treatment for low iron saturation typically includes a diet rich in iron, iron supplements, and medicinal iron.
Can anemia turn into leukemia?
Anemia and leukemia are both conditions that affect the blood. Moreover, people with the latter have an increased risk of developing anemia. However, anemia cannot cause leukemia, and these conditions remain different in several important respects.
What is the relationship between TIBC and serum iron?
The serum iron test measures the amount of iron in your blood. The total iron-binding capacity (TIBC) test looks at how well the iron moves through your body.
What is dangerously high ferritin levels?
Many laboratories consider serum ferritin levels greater than 200 ng/mL in women and greater than 300 ng/mL in men to be abnormal.
Is TIBC same as transferrin?
TIBC relates to the amount of transferrin in your blood that’s available to attach to iron. Although TIBC and transferrin are 2 different tests, they basically measure the same thing, so you’ll usually have either one or the other.
What is iron TIBC and ferritin panel?
total iron binding capacity (TIBC) – measures the transferrin capacity to bind iron; serum ferritin – measures the body’s ability to store iron.
What does low TIBC and UIBC mean?
A high TIBC, UIBC, or transferrin usually indicates iron deficiency, but they are also increased in pregnancy and with the use of oral contraceptives. A low TIBC, UIBC, or transferrin may also occur if someone has malnutrition, inflammation, liver disease, or nephrotic syndrome.
