Transferrin (mg/dL) = 0.7 x TIBC (μg of iron/dL) To measure TIBC in the blood is less expensive than a direct measurement of transferrin. [4] [5] The TIBC should not be confused with the unsaturated iron-binding capacity or UIBC (LOINC 2501-5, 22753-8 & 35216-1). The UIBC is calculated by subtracting the serum iron from the TIBC. [6]
Transferrin saturation (TS), measured as a percentage, is a medical laboratory value. It is the value of serum iron divided by the total iron-binding capacity [1] of the available transferrin, the main protein that binds iron in the blood, this value tells a clinician how much serum iron is bound.
Iron tests are groups of clinical chemistry laboratory blood tests that are used to evaluate body iron stores or the iron level in blood serum.. Other terms used for the same tests are iron panel, iron profile, iron indices, iron status or iron studies.
complete blood count [4] hemoglobin [5] serum iron [4] total iron binding capacity [4] serum ferritin [4] bone marrow examination (rarely) [4] Note: Iron therapy must be suspended 48 hours beforehand to ensure valid test results. [4] The normal range for hemoglobin is 13.8 to 17.2 grams per deciliter (g/dL) for men and 12.1 to 15.1 g/dL for ...
Serum iron is a medical laboratory test that measures the amount of circulating iron that is bound to transferrin and freely circulate in the blood. Clinicians order this laboratory test when they are concerned about iron deficiency, which can cause anemia and other problems. 65% of the iron in the body is bound up in hemoglobin molecules in red blood cells.
Acid–base and blood gases are among the few blood constituents that exhibit substantial difference between arterial and venous values. [6] Still, pH, bicarbonate and base excess show a high level of inter-method reliability between arterial and venous tests, so arterial and venous values are roughly equivalent for these.
High TIBC (total iron binding capacity), although this can be elevated in cases of anemia of chronic inflammation. It is possible that the fecal occult blood test might be positive if iron deficiency is the result of gastrointestinal bleeding ; although the sensitivity of the test may mean that in some cases it will be negative even with ...
decreased total iron-binding capacity; high transferrin saturation; Hematocrit of about 20-30%; The mean corpuscular volume or MCV is usually normal or low for congenital causes of sideroblastic anemia but normal or high for acquired forms.
