Iron plays a crucial role in haemoglobin (Hb) production and exists in various forms within the body. Transferrin, also referred to as siderophilin, is a liver-produced transport protein that governs iron absorption. Elevated levels of transferrin are linked to the body's immune response against infections. Total iron-binding capacity (TIBC) aligns with serum transferrin levels, although their correlation isn't straightforward. A standalone serum iron test lacks comprehensive value without concurrent TIBC and transferrin assessments, except in cases of iron poisoning. Transferrin saturation provides a more precise measure of iron saturation levels.
The combined results of transferrin, iron, and TIBC tests help diagnose different types of anaemia, assess iron-deficiency anaemia and evaluate conditions like thalassemia, sideroblastic anaemia, and haemochromatosis.
Ferritin is a protein that helps your body store and release iron. It is found in your body's cells, particularly in your liver, spleen, and bone marrow. Ferritin plays a critical role in maintaining healthy iron levels in your body, as iron is an essential nutrient that is needed for many important bodily functions, such as producing red blood cells and carrying oxygen throughout your body.
Our Iron Blood Test Kit tests for all these parameters and can help your GP if there are any concerns.
