Iron, Serum

Iron is an essential nutrient required to produce healthy red blood cells (RBCs). It is an important part of hemoglobin, the protein in RBCs that combines with oxygen and is transported to various body parts. Apart from this it improves cognitive function, helps produce energy, strengthens the immune system, and promotes healthier nails, skin, and hair. 

An Iron, Serum test is usually needed if an individual experiences symptoms suggestive of low iron levels, such as pale skin, fatigue, headaches, weakness, brittle nails, etc. Low levels of iron can be due to anemia, decreased intake of iron during pregnancy and lactation, or acute or chronic blood loss.

On the other hand, iron overload may cause tiredness, joint pain, abdominal pain, low sex drive, damage to the heart or liver, etc. High levels of iron (hemochromatosis) in the body may indicate a possible case of severe liver disease.

Most of the conditions associated with low iron levels can be successfully treated with iron supplements and iron-rich diets. Furthermore, iron overload (excess iron) can be treated with certain medicines/therapy advised by doctors and by refraining from iron-rich sources. 

Usually, overnight fasting is preferred, but not mandatory, before undergoing an Iron, Serum test. However, it is also important to inform the doctor about any of the medicines you are taking, especially iron supplements, as some of them may affect your iron levels and need to be adjusted or temporarily discontinued before the test.

Test result ranges are approximate and may vary between labs depending on the methodology and laboratory guidelines. Discuss your symptoms and specific test results with your doctor to help them correlate your clinical and laboratory findings. The test results will help doctors make informed decisions regarding your health. This may include lifestyle modifications, dietary changes, exercise, and supplements or medications if needed.
