Iron is vital for making haemoglobin, the protein in red blood cells responsible for oxygen delivery. However, too much or too little iron can impact the overall health. Instead of a single blood test, the doctor is more likely to recommend an iron profile test , which combines several tests, providing a complete view of iron’s status in the body. Each test measures a different aspect of iron storage, transport, and usage. Serum Iron Test The serum iron test measures the amount of iron in your blood at the time of the sample. Since levels of iron in the body can change during the day and after eating a meal, this iron test cannot diagnose iron deficiency on its own. It is interpreted with other iron markers, for a more accurate diagnosis. Ferritin Test The ferritin test measures ferritin, a protein that stores iron in the body. The ferritin test is one of the most accurate ways of measuring the body’s iron reserves, with low levels usually indicating the depletion o...
