To screen for iron-deficiency anemia, your doctor may order a blood test called a complete blood count (CBC) to see if you have lower than normal red blood cell counts, hemoglobin or hematocrit levels, or mean corpuscular volume (MCV) that would suggest anemia.

Does iron-deficiency show up in blood test?

Blood tests can show iron-deficiency anemia before symptoms develop. These tests include a complete blood count, which will measure your hemoglobin level. Iron-deficiency anemia makes your red blood cells appear smaller under a microscope.

What is iron labeled as on blood test?

Different types of iron tests include: Serum iron test, which measures the amount of iron in the blood. Transferrin test, which measures transferrin, a protein that moves iron throughout the body. Total iron-binding capacity (TIBC), which measures how well iron attaches to transferrin and other proteins in the blood.

What is iron level test called?

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).

How do I know if my iron levels are low?

1. Extreme fatigue.
2. Weakness.
3. Pale skin.
4. Chest pain, fast heartbeat or shortness of breath.
5. Headache, dizziness or lightheadedness.
6. Cold hands and feet.
7. Inflammation or soreness of your tongue.
8. Brittle nails.

Blood tests that check your iron levels - what the results can mean

What does ferritin test 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.

Are iron levels checked in a CBC?

Iron tests may be ordered when results from a routine complete blood count (CBC) show that a person's hemoglobin and hematocrit are low and their red blood cells are smaller and paler than normal (microcytic and hypochromic), suggesting iron deficiency anemia even though other clinical symptoms may not have developed ...

Is ferritin the same as iron?

Ferritin isn't the same thing as iron in your body. Instead, ferritin is a protein that stores iron, releasing it when your body needs it. Ferritin usually lives in your body's cells, with very little actually circulating in your blood.

Is hemoglobin the same as iron?

Hemoglobin is a protein in your body that contains iron and gives blood its red color. Hemoglobin is responsible for carrying oxygen from your lungs to nourish all of the tissues in your body. What is iron? Iron is a part of hemoglobin and an essential mineral found in foods we eat.

What is iron called on a CBC?

The CBC measures many parts of your blood. The test checks your hemoglobin and hematocrit (hee-MAT-oh-crit) levels. Hemoglobin is the iron-rich protein in red blood cells that carries oxygen to the body.

Is ferritin test part of CBC?

The ferritin test may be ordered, along with other iron tests, when a routine complete blood count (CBC) shows that a person's hemoglobin and hematocrit are low and their red blood cells are smaller and paler than normal (microcytic and hypochromic), suggesting iron deficiency anemia even though other clinical symptoms ...

Can you have normal ferritin but low iron?

Low serum iron and ferritin levels with an elevated TIBC are diagnostic of iron deficiency. While a low serum ferritin is virtually diagnostic of iron deficiency, a normal serum ferritin can be seen in patients who are deficient in iron and have coexistent diseases (eg, hepatitis or anemia of chronic disorders).

How serious is low ferritin?

A result of low ferritin is strong evidence of an iron deficiency. The body requires iron to make hemoglobin, which is a protein in red blood cells that transfers oxygen from the lungs around the body. Without enough iron, a person may develop anemia.

Can you have low ferritin but normal hemoglobin?

Iron deficiency without anemia can occur when a person has a normal hemoglobin, but below normal serum ferritin and/or transferrin saturation. Iron deficiency with anemia can occur when a person has low values of both serum ferritin and hemoglobin.

What blood test shows high iron levels?

Blood tests

The two key tests to detect iron overload are: Serum transferrin saturation. This test measures the amount of iron bound to a protein (transferrin) that carries iron in your blood. Transferrin saturation values greater than 45% are considered too high.

Is ferritin in red blood cells?

Ferritin is a protein that stores iron. Red blood cells need iron to form normally and carry oxygen around your body. Other parts of your body, such as your liver, bone marrow, and muscles, also need iron. Low levels of ferritin lead to iron-deficiency anemia.

What diseases cause low ferritin?

• Anemia [2]
• Fatigue [3]
• Hair loss [4, 5, 6, 7]
• Fibromyalgia [8]
• IBD [9]
• Hypothyroidism [10]
• Depression [11]
• Anxiety [12]

What is dangerously low ferritin levels?

Serum ferritin is typically less than 10 ng/mL in severe iron deficiency associated with anemia. In iron deficiency without anemia, ferritin is typically in the range of 10-20 ng/mL.

How can I raise my ferritin levels quickly?

Consuming iron-rich foods improves iron stores and ferritin levels. These include green leafy vegetables, cocoa powder, dark chocolate, oatmeal, cereals, wheat germ, beans and tofu, lamb and beef, nuts, pumpkin and squash seeds, liver and mollusks, among others.

What are the 3 stages of iron deficiency?

The serum transferrin receptor level rises (> 8.5 mg/L). During stage 3, anemia with normal-appearing RBCs and indices develops. During stage 4, microcytosis and then hypochromia develop. During stage 5, iron deficiency affects tissues, resulting in symptoms and signs.

Can lack of iron cause dry mouth?

Swelling and soreness of the tongue and mouth

Signs include a swollen, inflamed, pale, or strangely smooth tongue ( 18 ). Iron deficiency may also cause other symptoms around your mouth, such as (19): dry mouth.

What ferritin level is anemic?

If symptoms are in accordance with iron deficiency, the patient should be considered iron deficient at least up to a serum ferritin concentration of 100 μg/L, or even much higher, if the patient has an inflammatory condition, kidney disease or fatty liver 2, 3.
