Iron deficiency is one of the most common nutritional deficiencies. It develops slowly: first the body’s iron stores run low, and only later does anaemia appear. That is why many people feel tired for months without knowing why.
Signs of low iron
- Tiredness and weakness
- Shortness of breath on exertion
- Pale skin, dizziness
- Cold hands and feet
- Hair loss, brittle nails
These signs can have other causes too, so they alone don’t tell you whether iron is the problem.
Who is at higher risk
- Women with heavy periods
- Pregnant women
- Children and teenagers during growth spurts
- Vegetarians and vegans
- Regular blood donors
- People with digestive conditions that affect absorption
Why ferritin
Ferritin is the protein that stores iron. Its level in the blood reflects your iron stores, so low ferritin often shows a deficiency even before anaemia develops.
How to check at home
The Testera Iron Deficiency Test measures ferritin from a drop of fingertip blood and shows in 5 minutes whether your iron stores are low.

What to do if the result is low
See a doctor to find the cause: diet, blood loss or poor absorption. Don’t take iron supplements for a long time without checking, as too much iron can also be harmful.
Iron in food
Iron is found in red meat, liver and fish, as well as in legumes, dark green leafy vegetables and fortified cereals. Vitamin C with a meal helps the body absorb iron from plant foods, while tea and coffee with meals reduce absorption.
