Self-tests are not a substitute for professional diagnosis. If you have symptoms, do not use a self-test, speak to your doctor instead. All medical tests have inherent limitations and can produce false results. Consider the emotional impact of your results before deciding to test, and whether you have a positive or negative result, always seek medical guidance if you have health concerns.

Contains 1 test.
The test is a manual, qualitative, immunochromatographic (lateral flow), screening self-test for the immunological detection of ferritin in a finger prick whole blood sample. The test is designed for use at home by members of the public to screen for iron deficiency.
General information
Iron deficiency anaemia is a common and significant health issue worldwide, particularly affecting women of childbearing age and pregnant women. It happens when the body doesn't have enough healthy red blood cells, and lower levels of haemoglobin.
Haemoglobin is the vital protein that carries oxygen around the body, and iron is a key component of it. Common signs of iron deficiency can include headaches, feeling tired, heart palpitations, and hair loss. While a full blood count is often used, measuring ferritin levels provides a straightforward and reliable way to identify iron deficiency anaemia. Ferritin is a protein that stores iron, and low levels may indicate reduced iron levels in the body.
A reduction in iron levels can occur for many reasons including, during pregnancy, periods of rapid growth, insufficient iron in your diet, poor absorption of iron, blood loss, menstruation, abnormal bleeding, or ulcers. Knowing you have a low iron level can help you seek advice from your doctor to reduce the risks of long-term health problems associated with iron deficiency anaemia.
Time to result
The test gives a result in 10 minutes at home.
Warnings
A screening test for a single biomarker, such as ferritin, is not a diagnosis.
Not following the instructions exactly as written in the instructions for use may cause a false positive or false negative result.
Do not change your medication, diet or lifestyle solely on the basis of a self-test - always discuss your result with an appropriate healthcare professional first.
This test is unsuitable if you have been diagnosed with haemochromatosis.
Accuracy
This test has a cut-off of 20 ng/mL of ferritin for a positive result and is calibrated to the WHO 19/118 international standard. The test has an overall agreement of 98% (92.58-100%)* sensitivity of 100%, and specificity of 92.6% with laboratory tests for ferritin. Although this test is reliable for the detection of ferritin, all medical tests can give false positive or false negative results.
IMPORTANT: These figures refer to the agreement of the SELFCHECK test with laboratory ferritin tests, and not to the accuracy of tests for the diagnosis of iron deficiency anaemia.
