Ferritin Blood Test: Why Is It Recommended For Covid-19
A ferritin blood test helps to detect the amount of a blood protein known as ferritin that stores iron. We consume certain iron-rich products, and our body immediately uses the iron to make oxygen in our blood, but at the same time, it also stores some amount in case it doesn’t get enough iron from the food that we eat. The ferritin protein stores this iron. In simpler terms, a ferritin blood test reveals how much iron is present in our body.
What Is The Role of Iron In Our Body?
Without iron, our bodies are not equipped to form haemoglobin (Hb). Every red blood cell (RBC) has haemoglobin which ultimately carries oxygen from our lungs to the rest of the body. Iron, haemoglobin and oxygen are all interconnected phenomena. Unfortunately, our bodies don’t make iron, and we have to get it from supplements or food.
The normal range for blood ferritin is:
Men: 24 to 336 micrograms per litre
Women: 11 to 307 micrograms per litre
Causes of Low Ferritin Blood Levels
If the value in the ferritin blood test comes lower than normal, it means that your body stores less iron and you have an iron deficiency which can also lead to anaemia – a condition of lack of oxygen in your blood.
Symptoms of Low Ferritin Blood Levels
- Dizziness and weakness
- Rapid heartbeat
- Frequent headaches
- leg pain
- Ringing sensation in the ears, or tinnitus
Causes of High Ferritin Blood Levels
If the ferritin blood test value comes higher than normal, it means that your body has a tendency to store too much iron. High levels of iron can lead to liver disease, rheumatoid arthritis and overactive thyroid.
Symptoms of High Ferritin Blood Levels
- Joint pain
- Stomach pain
- Lack of energy
- Weight loss
- Low sex drive
- Heart problems such as arrhythmias
- Hyperpigmentation of skin
How is Ferritin Blood Test Connected To Covid-19?
Many pieces of research have shown that patients with higher ferritin levels are more prone to develop a severe pulmonary involvement in covid-19. The more the ferritin, the worse the prognosis. However, ferritin levels are not the only ones to be blamed for covid-19, but it has shown a rising trend that can even denote cytokine storm. Covid-19 virus and even mucormycosis can survive on higher iron stores.
