How accurate is serum iron?
Taking ferritin as gold standard, the sensitivity and specificity of serum iron was 63.5% and 38.6%, respectively; while that of TIBC was 64.5 % and 42.8%, respectively. Ferritin showed poor correlation with iron, TIBC and transferrin saturation.
What is normal serum iron 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)
Is serum iron the same as iron?
The serum iron test measures the amount of iron in the liquid portion of blood. Serum iron is almost always measured with other iron tests, such as serum ferritin, transferrin and total iron-binding capacity (TIBC).
Does serum ferritin contain iron?
In contrast to intracellular ferritin, serum ferritin is iron-poor and consists almost exclusively of L-subunits [32], with the addition of glycosylated subunits (G-subunits), which are similar to the L-chain [33].
What is the iron level for a woman?
The normal serum iron level for women is 60 mcg/dL to 140 mcg/dL. Total iron-binding capacity is 250 mcg/dL to 450 mcg/dL.
What happens if serum iron is low?
Symptoms of iron-deficiency anemia are related to decreased oxygen delivery to the entire body and may include: Being pale or having yellow “sallow” skin. Unexplained fatigue or lack of energy. Shortness of breath or chest pain, especially with activity.
What does serum ferritin indicate?
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 body’s iron stores are low and you have iron deficiency. As a result, you could be anemic.
What should the results of a serum iron test be?
Normal serum iron test results. Serum iron is measured in micrograms of iron per deciliter of blood (mcg/dL). The following are considered normal ranges for a serum iron test: Transferrin is a protein in the blood that transports iron throughout your body.
Can a low serum iron level be a sign of iron deficiency?
Unfortunately, a low serum iron level in this setting is frequently misinterpreted as evidence of iron deficiency, a major diagnostic error that can be avoided by simultaneous examination of the transferrin level, which in this context is subnormal or in the low normal range.
Is it normal to have a 100 percent iron saturation?
Percent saturation (100 x serum iron/TIBC) is usually normal or decreased in persons who are iron deficient, pregnant, or are taking oral contraceptive medications. Persons with chronic inflammatory processes, hemochromatosis, or malignancies generally display low transferrin.
How are iron and ferritin measured in a laboratory?
Clinical laboratories typically use conventional units for iron-status indicators: iron, total iron-binding capacity (TIBC), and erythrocyte protoporphyrin (EPP) are calculated in micrograms per deciliter (µg/dL), ferritin in nanograms per milliliter (ng/
