Iron Deficiency Plus Test
GetTested’s Iron Deficiency Plus Test provides a comprehensive overview of your iron status by measuring iron, ferritin, transferrin, total iron-binding capacity (TIBC), and transferrin saturation. Unlike a standard iron test, this extended panel offers more accurate insights into iron stores, transport, and utilization, helping to detect both deficiency and overload.
Iron deficiency is common and may cause fatigue, pale skin, hair loss, and reduced concentration, while iron overload can lead to organ damage if left untreated—making accurate testing essential for early detection and management.

Iron Deficiency Plus Test
The Iron Deficiency Plus Test from GetTested provides a comprehensive assessment of iron status by measuring iron, ferritin, transferrin, total iron-binding capacity (TIBC), and transferrin saturation. By analyzing this extended panel, the test offers deeper insights than measuring iron alone, helping to detect both early and advanced stages of iron deficiency or overload.
What does the test measure?
- Iron: The amount of circulating iron in the blood, which can fluctuate throughout the day and is best interpreted together with other markers.
- Ferritin: Reflects the body’s iron stores and is one of the most reliable indicators of iron deficiency.
- Transferrin: A protein that binds and transports iron in the blood. Levels rise when iron stores are low.
- TIBC (Total Iron-Binding Capacity): Indicates the blood’s capacity to bind iron, often elevated in iron deficiency.
- Transferrin saturation: The percentage of transferrin bound to iron, showing how efficiently iron is being transported and utilized.
Why is this panel important?
Measuring iron alone can be misleading, since levels fluctuate and may appear normal even in deficiency. By including ferritin, transferrin, TIBC, and transferrin saturation, the test provides a more accurate picture of whether the body has sufficient iron stores, how well iron is transported, and whether there are signs of deficiency or overload.
Symptoms of iron deficiency
Iron deficiency is one of the most common nutritional deficiencies worldwide and may cause:
- Persistent fatigue and weakness
- Pale skin
- Shortness of breath or rapid heartbeat
- Dizziness or headaches
- Brittle nails or hair loss
- Restless legs or reduced concentration
Who should consider this test?
The Iron Deficiency Plus Test may be relevant if you:
- Experience symptoms suggestive of iron deficiency
- Have heavy menstrual bleeding
- Follow a vegetarian or vegan diet
- Are pregnant or planning pregnancy
- Engage in endurance sports
- Have known gastrointestinal issues affecting absorption
It is also useful for individuals with conditions linked to iron overload, such as hemochromatosis.
How the test works
The test is performed using a simple dried blood spot (DBS) sample, collected at home with a finger prick. For best accuracy, the sample should be taken in the morning on an empty stomach. The sample is analyzed in our accredited laboratory, and results are delivered digitally, giving you secure and convenient access to your iron status insights.
