Doctors consider anemia, iron deficiency during pregnancy as an obstetric threat so it is necessary to get tested for ferritin during pregnancy. The Ferritin test means a dosing examination of the iron that is in the body of the pregnant woman to determine whether the pregnant body lacks or excess iron. From there, there is a direction to supplement or eliminate iron out of the body.

1. What is ferritin test?

Ferritin is a protein cell in the blood that contains iron. The ferritin dosing test is a test that measures the amount of protein in the blood to diagnose the production of ferritin proteins. Often applied to diseases of the liver, diabetes, armor, cancer and other inflammatory conditions.

Going for a ferritin test will help your doctor understand how much iron your body is stored. If the ferritin test shows lower than normal levels of ferritin in the blood, it means that the body's iron reserves are low and there is iron deficiency.

If the ferritin test shows to be higher than normal, it may show that there is a condition caused to the body to store too much iron. It can also point to liver disease, rheumatoid arthritis, other inflammatory conditions, armor or some cancers that can also cause high levels of ferritin in the blood.

2. Why ferritin testing is required during pregnancy

  • Excess iron can also be caused by mutations in the genes HAMP, HFE HFE2, SLC40A1 and TFR2. Mutations in these genes reduce the control of iron absorption during digestion and alter the distribution of iron to parts of the body.

Pregnant woman threatens miscarriage

Pregnant mothers with iron deficiency will present with dizziness, headache, fatigue,…

Pregnant women with excess iron will lead to many serious consequences for both mother and baby:

  • When the amount of iron in the body increases excessively leads to an increase in free iron levels and hemoglobin hemoglobin hemoglobin levels. This can make it difficult to transport blood and oxygen from the mother to the fetus.
  • Babies are born with underweight, premature birth and even death.
  • The excess iron accumulated long in the pregnant body will put pressure on the liver and spleen, which in the long run leads to spleen failure, liver failure, diabetes mellitus due to pancreatic dysfunction. Excess iron also causes cardiovascular diseases, stroke, parkinson's and cancer.

  • Children of mothers with gestational anemia at an early stage of pregnancy have a higher risk of cardiovascular disease than other children; long-term effects on a child's brain development and impair their learning ability due to defects in the formation of myelin due to iron deficiency.

Therefore, doctors have considered anemia, iron deficiency during pregnancy as an obstetric threat so it is necessary to go for a ferritin test during pregnancy.
