What is an iron test?
Iron is a crucial mineral that is essential for maintaining healthy body practices. Iron is essential for the cells to perform optimally and this forms the basis of all our metabolic functions. Not only this, iron provides us energy for functioning, improves immunity, and muscle strength. Since the human body cannot produce iron, it is gained from the food that we eat. If our diet does not contain foods fortified with iron, and this is especially true for vegetarians, a deficiency of iron occurs. Other reasons for low iron levels include age, pregnancy, and conditions like celiac disease. This leads to a condition known as anaemia and has extremely discomforting symptoms. This is where an iron test comes in. Also known as ferritin test, this is a blood test that measures different substances in the body like iron in the liquid portion of the blood, the availability and reserve capacity of transferrin, amount of stored iron in the body, levels of iron-binding proteins, etc. All these are ordered and interpreted together to help diagnose if there is an iron deficiency or overload in the blood. Ferritin test can be done either at a hospital or lab. However, with the advancement in technology and telemedicine, anaemia test at home is now a possibility.
Which tests are included in the iron test?
