A ferritin blood test measures the level of ferritin in your blood. Ferritin is a protein that stores iron inside your cells. This test can tell whether you are getting too much or too little iron. Iron is essential for making healthy red blood cells, which carry oxygen throughout the body. It also plays a vital role in healthy muscles, bone marrow, and organ function.
The ferritin blood test helps doctors assess your iron levels and diagnose conditions like iron deficiency anemia, hemochromatosis (iron overload), and other health issues related to iron storage.
Here's how the test works:
- A small sample of your blood is taken.
- The blood sample is analyzed in a laboratory to determine the amount of ferritin in your blood.
- The results are then interpreted by a doctor to determine whether your iron levels are within the normal range.
Normal ferritin levels vary depending on age, sex, and other factors. It's essential to consult your doctor to understand what your results mean.
Here are some factors that can affect your ferritin levels:
- Iron deficiency: Low ferritin levels can indicate iron deficiency anemia.
- Iron overload: High ferritin levels can indicate hemochromatosis or other iron overload conditions.
- Inflammation: Ferritin levels can be elevated during inflammation or infection.
- Pregnancy: Ferritin levels tend to be lower during pregnancy due to increased iron requirements.
If you have any concerns about your ferritin levels, talk to your doctor.
