STTM Ferritin Blood Test

Why is this test important? Ferritin is a blood cell protein that acts as your body's storehouse for iron. Many patients who suffer from hypothyroidism (underproduction of thyroid hormones) also may have low ferritin levels, which signal that the body has an iron deficiency. However, this test also screens for abnormally high ferritin levels, which can lead to several serious medical conditions.

What does the test include? The HealthCheck USA STTM ferritin blood test provides an accurate measure of your body's reserve supply of iron. For a complete picture of iron overload, other tests - such as total iron binding capacity (TIBC) and hereditary hemochromatosis DNA screening - may be required. Prepare to fast 12 hours before taking this test to ensure the most accurate data. The full panel of results will be analyzed by an accredited medical laboratory, and can be accessed on the HealthCheckUSA Web site within four business days after a blood test.

Who should be tested? Strongly consider testing if you have been diagnosed with hypothyroidism or are experiencing symptoms such as:

• unusual weight gain
• lethargy
• dry skin
• a constant feeling of cold
• constipation

Other conditions that may suggest low ferritin levels include anemia, which is characterized by:

• pale skin
• less pink lips and nail beds
• irritability
• fatigue
• dizziness
• rapid heartbeat

If you have children exhibiting these conditions, strongly consider testing, since anemia can cause developmental delays and behavioral problems. To check for iron overload, consider testing if you experience joint pain, fatigue or lack of energy, abdominal pain, loss of sex drive or heart problems. High ferritin levels have been linked to patients with hemochromatosis, a hereditary disorder that can lead to arthritis, liver disease, congestive heart failure, impotence or damage to the pancreas. Bear in mind that some patients never exhibit symptoms from iron overload.
