Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: The patient should be fasting 9-12 hours prior to collection and collection should be done in the morning.

When is an Iron Total test ordered?

An Iron Total test may be ordered in various situations:

1. Evaluation of Iron Deficiency: It is commonly ordered to assess iron levels and diagnose iron deficiency anemia. Symptoms such as fatigue, weakness, pale skin, and shortness of breath may prompt healthcare providers to investigate iron status.

2. Monitoring Iron Replacement Therapy: For individuals receiving iron supplementation or undergoing treatment for iron deficiency anemia, regular monitoring of iron levels helps assess treatment effectiveness and guide dosing adjustments.

3. Investigation of Iron Overload: In certain cases, an Iron Total test may be ordered to evaluate iron overload disorders, such as hereditary hemochromatosis. High levels of iron can have detrimental effects on various organs and warrant further investigation.

What does an Iron Total blood test check for?

Iron is a necessary ingredient for survival and is a critical component of hemoglobin, the protein in red blood cells that binds oxygen in the lungs and releases it to other parts of the body. It is required in small amounts to help form normal red blood cells and is a critical part of hemoglobin, the protein in RBCs that binds oxygen in the lungs and releases it as blood circulates to other parts of the body.

By detecting numerous components in the blood, iron tests are ordered to determine the quantity of iron in the body. These tests are frequently ordered at the same time, and the data are analyzed together to determine the diagnosis and/or monitor iron deficiency or overload.

The level of iron in the liquid component of the blood is measured by serum iron.

Low iron levels can cause anemia, resulting in a decrease in the production of microcytic and hypochromic RBCs. Large amounts of iron, on the other hand, might be hazardous to the body. When too much iron is absorbed over time, iron compounds build up in tissues, particularly the liver, heart, and pancreas.

Normally, iron is absorbed from food and distributed throughout the body by binding to transferrin, a liver protein. About 70% of the iron delivered is used in the synthesis of hemoglobin in red blood cells. The rest is stored as ferritin or hemosiderin in the tissues, with minor amounts being utilized to make other proteins like myoglobin and enzymes.

Insufficient intake, limited absorption, or increased dietary requirements, as observed during pregnancy or with acute or chronic blood loss, are all signs of iron deficiency. Excessive intake of iron pills can cause acute iron overload, especially in children. Excessive iron intake, genetic hemochromatosis, multiple blood transfusions, and a few other disorders can cause chronic iron overload.

Lab tests often ordered with an Iron Total test:

When an Iron Total test is ordered, it is often accompanied by several other tests to provide a comprehensive view of iron metabolism and related aspects of blood health. Here are some common tests ordered alongside an Iron Total test:

1. Ferritin:

   • Purpose: Ferritin is a protein that stores iron in the body. Measuring ferritin levels provides an indication of the body's iron stores.
   • Why Is It Ordered: To differentiate between various types of anemia and assess iron stores more accurately. Ferritin is the most sensitive test for iron deficiency anemia.

2. Total Iron Binding Capacity (TIBC):

   • Purpose: TIBC measures the maximum amount of iron that can be bound by proteins in the blood (primarily transferrin).
   • Why Is It Ordered: These tests help evaluate how much transferrin (a protein that transports iron) is not carrying iron. High TIBC can indicate iron deficiency, while low levels can suggest iron overload.

3. Complete Blood Count (CBC):

   • Purpose: To evaluate overall blood health, including red blood cells, white blood cells, and platelets.
   • Why Is It Ordered: CBC can help diagnose anemia (low red blood cell count or hemoglobin) and provide information on the size and color of red blood cells, which can indicate iron deficiency or other types of anemia.

4. Hemoglobin and Hematocrit:

   • Purpose: Part of the CBC, these tests measure the amount of hemoglobin in the blood and the proportion of blood made up of red blood cells.
   • Why Is It Ordered: To assess the severity of anemia and monitor response to iron therapy.

5. Reticulocyte Count:

   • Purpose: To measure the number of young red blood cells in the blood, indicating how quickly they are being produced by the bone marrow.
   • Why Is It Ordered: To assess bone marrow response in anemia, particularly after treatment for iron deficiency.

6. Vitamin B12 and Folate Tests:

   • Purpose: Both vitamin B12 and folate are crucial for red blood cell production.
   • Why Is It Ordered: To rule out vitamin deficiencies that can cause anemia with a presentation similar to iron deficiency anemia.

7. Liver Function Tests:

   • Purpose: To assess liver health.
   • Why Is It Ordered: Liver disease can impact iron metabolism and can be a cause of iron overload.

8. Serum Soluble Transferrin Receptor (sTfR):

   • Purpose: To measure the level of transferrin receptors in the blood.
   • Why Is It Ordered: In iron deficiency anemia, sTfR levels are elevated. This test can be particularly useful in distinguishing iron deficiency anemia from anemia of chronic disease.

These tests, together with an Iron Total test, provide a comprehensive evaluation of a person's iron status and help in diagnosing the cause of abnormalities in iron levels, such as iron deficiency anemia or hemochromatosis (iron overload). The specific tests selected will depend on the individual’s symptoms, medical history, and initial test results.

Conditions where an Iron Total test is recommended:

An Iron Total test is useful in the evaluation and management of various conditions, including:

1. Iron Deficiency Anemia: Iron Total testing is crucial in diagnosing and monitoring iron deficiency anemia, a common condition characterized by low iron levels and inadequate red blood cell production.

2. Iron Overload Disorders: Individuals with suspected iron overload disorders, such as hereditary hemochromatosis or secondary iron overload, may require an Iron Total test to evaluate iron levels and guide appropriate management.

How does my healthcare provider use an Iron Total test?

Healthcare providers use the results of an Iron Total test to:

1. Diagnose Iron Deficiency Anemia: Low iron levels and subsequent iron deficiency anemia can be diagnosed based on the test results and clinical presentation. Treatment options, such as iron supplementation, dietary modifications, or further investigations, can be initiated accordingly.

2. Monitor Iron Replacement Therapy: Regular monitoring of iron levels helps healthcare providers assess the response to iron supplementation or other iron-replenishing treatments. Adjustments to the treatment plan can be made based on the test results to ensure optimal iron status.

3. Evaluate Iron Overload: High iron levels may indicate iron overload disorders, such as hereditary hemochromatosis. Further evaluation and management strategies can be implemented based on the test results, including therapeutic phlebotomy or iron chelation therapy.

It is important to note that the interpretation and utilization of Iron Total test results should be done by a qualified healthcare provider who considers the patient's medical history, symptoms, and other relevant factors. Treatment decisions are individualized based on the specific clinical context.

Additional information about iron

A balance between the quantity of iron received into the body and the amount of iron lost is required to maintain normal iron levels. Because a tiny quantity of iron is lost each day, a deficiency will develop if too little iron is consumed. In healthy persons, there is usually enough iron to prevent iron deficiency and/or iron deficiency anemia, unless they eat a bad diet. There is a greater need for iron in some circumstances. People who have persistent gut bleeding or women who have heavy menstrual periods lose more iron than they should and can develop iron deficiency. Females who are pregnant or breastfeeding lose iron to their babies and may develop an iron shortage if they do not consume enough supplemental iron. Children may require additional iron, especially during periods of rapid growth, and may suffer iron shortage.

Low serum iron can also arise when the body is unable to adequately utilize iron. The body cannot correctly utilize iron to generate additional red cells in many chronic disorders, particularly malignancies, autoimmune diseases, and chronic infections. As a result, transferrin production slows, serum iron levels drop because little iron is absorbed from the stomach, and ferritin levels rise. Malabsorption illnesses like sprue syndrome can cause iron deficiency.
