What is a Serum Iron Test?
The serum iron test is a simple blood test that measures the iron level in your blood. Serum refers to the liquid component of blood that remains after the blood cells (red and white blood cells, platelets) have been removed. Iron is an essential mineral for carrying oxygen to your body's cells. Doctors use the results to diagnose and monitor iron-related disorders, ensuring proper treatment and overall health.
Need for Serum Iron Test
A serum iron test is recommended for individuals suspected of conditions related to iron metabolism or absorption. The suitable candidates for this test include:
People with symptoms of anaemia, such as fatigue, weakness, shortness of breath, or pale skin.
Inflammatory bowel disease may have difficulty absorbing iron from their diet.
Any person who has undergone gastrointestinal surgery may have reduced absorption of iron.
Diagnosed with a blood disorder, such as thalassemia or sickle cell anaemia.
Pregnant individuals may require additional iron to support foetal growth and development.
Family history of iron overload disorders, such as hemochromatosis or with a history of liver disease or liver damage.
Lead exposure or suspected lead poisoning.
Benefits of Serum Iron Test
This serum iron test is essential for diagnosing and managing iron-related disorders. The benefits include
Diagnosis of Iron-Deficiency AnaemiaIron deficiency anaemia is a common type of anaemia that occurs when the body does not have less than the required iron to produce haemoglobin. This protein carries oxygen in the blood.
In this case, the serum iron test helps to diagnose anaemia.
Monitoring Treatment of Iron-Deficiency AnaemiaThe serum iron test can be used to monitor the effectiveness of treatment by measuring the level of iron in the blood. If the iron levels increase over time, the treatment is working.
Early Detection of Iron OverloadIron overload is a condition with too much iron in the body. This can lead to organ damage and other serious health problems. This blood test can help detect iron overload early on by measuring the iron level in the blood.
Diagnosis of HemochromatosisHemochromatosis is an inherited disorder in which the body absorbs more than the required iron. Over time, the excess iron can cause damage organs such as the liver, heart, and pancreas.
The serum iron test can help diagnose hemochromatosis by measuring the iron level in the blood. Genetic testing may be necessary to confirm the diagnosis if the levels are too high.
Evaluation of Iron During PregnancyThe body needs more iron to support the growing foetus. The serum iron test can help evaluate the iron status of pregnant women and detect iron deficiency anaemia early. This, in turn, can help reduces the risk of complications during pregnancy.
Diagnosis of Lead PoisoningLead poisoning is a severe condition that can cause a range of health problems, including developmental delays, behavioural issues, and organ damage.
The test can diagnose lead poisoning by measuring the lead level in the blood.
Preparation of Serum Iron Test
Specific preparations are often required before the serum iron test to ensure accurate results. Follow the doctor's instructions to ensure accurate test results and effective management of any iron-related conditions. The preparation of the test includes:
Fasting: Your doctor may ask you to fast for 12 hours before the test, which means not eating or drinking anything except water during this period.
Medications: Inform your healthcare provider about any medications or supplements you currently take, as some may interfere with the test results. Follow their advice on whether to discontinue any specific medicines before the test.
Avoid Vitamin C Supplements: Vitamin C can enhance iron absorption, so it's advisable to avoid vitamin C supplements or excessive consumption of vitamin C-rich foods for a day before the test.
Stay Hydrated: Drink plenty of water before the test to ensure you are well-hydrated, as dehydration may affect blood volume and, consequently, the accuracy of the test results.
Rest Before the Test: Get a good night's sleep before the test to reduce stress and fatigue, which can impact iron levels in the body.
Serum Iron Test Procedure
The serum iron blood test is a routine procedure that is relatively quick and safe. The doctor will discuss the test results with you and provide appropriate guidance based on the findings. The procedure includes:
Blood Sample Collection: A healthcare professional will collect blood from your vein, usually from the arm. Before drawing the blood, they will clean the area with an antiseptic to prevent infection.
Needle Insertion: The healthcare provider will use a needle to access the vein and draw the blood into a sterile container. You may feel a brief prick or stinging sensation during this process.
Pressure and Bandage: After the blood sample is collected, the needle will be removed, and gentle pressure will be applied to the puncture site to stop bleeding. A bandage will then be placed over the site to protect it.
Labelling and Transport: The collected blood sample will be labelled with your details and sent to the laboratory for analysis.
Aftercare of Serum Iron Test
After the serum iron blood test, taking care of yourself is essential to ensure a smooth recovery. The aftercare includes:
Apply Pressure: Keep the bandage on the puncture site for a few hours after the test. Applying gentle pressure to the area can help minimise bruising and promote clotting.
Stay Hydrated: Drink plenty of water after the test to help your body replenish the blood volume and prevent dehydration.
Avoid Heavy Lifting: Refrain from engaging in heavy lifting or strenuous activities for a few hours after the test to avoid any potential complications or discomfort at the puncture site.
Monitor for Adverse Reactions: While rare, if you experience severe pain, swelling, or bleeding at the puncture site, contact your healthcare provider immediately.
Rest: Get adequate rest and avoid excessive physical exertion for the rest of the day, aiding in quicker recovery.
Results of Serum Iron Test
The serum iron test results are typically available within 6 to 24 hours after collecting the blood sample. Patients can obtain their test reports by contacting their healthcare provider or through an online patient portal.
Interpretation of the ESR Test
The defined serum iron normal range tends to vary from one lab to another. The normal values are:
Total Iron-Binding Capacity (TIBC): 240 to 450 mcg/dL
Total Serum Iron: 26 to 170 mcg/dL in women and 76 to 198 mcg/dL in men
Transferrin Saturation: 204 to 360 mg/dL
Iron: 60 to 170 mcg/dL
Serum Iron Test Above Normal
The serum iron test results may sometimes show iron levels above normal. Several factors can lead to higher-than-normal serum iron levels, indicating potential health issues. Here are some common causes of an elevated serum iron test:
Iron Overload Disorders: Conditions like hereditary hemochromatosis and secondary hemochromatosis can cause excess iron to accumulate in the body. It leads to elevated serum iron levels.
Frequent Blood Transfusions: Receiving regular blood transfusions, either for medical conditions or chronic anaemia, can increase iron levels in the blood over time.
Excessive Iron Supplementation: Taking iron supplements in excess of the recommended dose can cause an iron overload in the body.
Liver Disease: Certain liver disorders, such as alcoholic liver disease and nonalcoholic fatty liver disease, can disrupt iron metabolism and increase serum iron levels.
Hemolytic Anaemia: Conditions that cause the premature destruction of red blood cells, like hemolytic anaemia, can release additional iron into the bloodstream.
Serum Iron Test Below Normal
Low serum iron levels can indicate iron deficiency. Here are some common causes of a below-normal serum iron test:
Iron Deficiency Anaemia: The most common cause of low serum iron levels is iron deficiency anaemia. It occurs when the body lacks sufficient iron to produce haemoglobin, the protein in red blood cells that carries oxygen.
Inadequate Dietary Intake: A diet lacking in iron-rich foods, such as red meat, leafy greens, and beans, can lead to insufficient iron absorption and low serum iron levels.
Chronic Blood Loss: Conditions or factors that cause chronic blood loss, such as gastrointestinal bleeding, menstrual bleeding (in women), or frequent blood donation, can deplete the body's iron stores.
Malabsorption Disorders: Certain medical conditions, like celiac disease and inflammatory bowel disease, can affect the absorption of nutrients, including iron, leading to iron deficiency and lower serum iron levels.
Pregnancy: During pregnancy, the body's iron requirements increase to support fetal development, and if dietary intake is inadequate, it can result in low serum iron levels.
Treatment Plan After Test
Treatment is needed to address the underlying causes of abnormal serum iron levels, whether too high or too low. Proper treatment helps restore iron balance in the body, improves overall health, and prevents potential complications associated with iron-related disorders.
Treatment of Serum Iron Above Normal
Managing the causes of high serum iron levels is crucial to prevent complications and maintain overall health. Here are some treatment options for elevated serum iron levels:
For hereditary hemochromatosis, therapeutic phlebotomy (blood removal) is a common treatment to reduce iron levels.
Iron chelation therapy may be used if frequent transfusions cause elevated iron levels. This involves medications that help the body excrete excess iron.
Stop iron supplements immediately and consult a healthcare provider for further guidance on managing iron levels safely.
Treating the underlying liver condition and managing iron intake through diet or medications can help regulate iron levels.
Treatment of Serum Iron Below Normal
When a person's serum iron is low, it may signify specific health conditions that require attention and appropriate management. Treatment of with low serum iron includes:
Iron supplements can help replenish iron levels and treat iron deficiency anaemia.
Incorporating more iron-rich foods into the diet can help improve iron absorption and boost serum iron levels. Consult a healthcare provider or a registered dietitian for personalized dietary advice.
Pregnant women may need iron supplementation to meet iron requirements during pregnancy.
Risks and Complications of Serum Iron Test
When a person undergoes a serum iron test, they may experience mild pain or a pricking sensation when the blood is drawn. This is a usual side effect of blood draws and is usually temporary.
The pain should subside soon after the procedure is complete. Additionally, a person may experience slight bleeding or develop a small bruise at the site. This is also a common side effect and should not cause concern. However, in rare cases, a person may experience more serious complications due to a serum iron test. These can include:
Infection: If the equipment used for the blood draw is not sterilised correctly, a person may develop an infection in the pricked area. The symptoms of an infection include redness, swelling, and tenderness at the site of the puncture. In some cases, a person may also experience fever or chills. If a person suspects an infection, they should seek medical attention immediately.
Excessive Bleeding: While bleeding after a blood draw is normal, excessive bleeding can occur in rare cases. This can be due to a person's blood not clotting properly. A person who experiences excessive bleeding after a blood draw should apply pressure to the site and seek medical attention if the bleeding does not stop within a few minutes.
Fainting: Some people may experience fainting or lightheadedness after a blood draw. This can be due to a sudden drop in blood pressure. A person who feels faint should lie down and elevate their legs to help increase blood flow to the brain. It is also important to inform the healthcare provider of any previous fainting episodes to ensure proper precautions are taken during the blood draw.
Cost of Serum Iron Test
The serum iron test cost can vary depending on several factors. Before getting the test, key factors like the healthcare provider, geographical location, and insurance coverage are worth considering. Here are a few of the factors that can affect the cost of a serum iron test:
Insurance Coverage: Though the insurance company does not cover blood tests, a few exceptions exist. Some insurance contains packages for blood tests as a preventive measure. Other corporate insurance policies hold the same policy for blood tests.
Geographical Location: The cost of a serum iron test can vary depending on the patient's location. Tests performed in urban areas or areas with a higher cost of living may be more expensive than those performed in rural areas.
Type of Test: The cost of a serum iron test can also depend on the specific test type ordered. Additional tests, like a complete blood count (CBC) or transferrin saturation test, may be necessary for an accurate diagnosis and can increase the overall cost.
Laboratory Fees: The laboratory that performs the test may charge additional fees, such as processing or handling fees, which can increase the overall cost of the test.
