Iron Status
Iron is an essential mineral crucial for oxygen transport, energy production, and overall health. Maintaining balanced iron levels is vital, as both deficiency and excess can lead to significant health complications. Low iron levels can cause fatigue, weakness, pallor, and anaemia, while excessive iron may contribute to organ damage, liver disease, and other long-term health concerns.
Your doctor may recommend an Iron Status Test if you experience persistent fatigue, dizziness, or weakness, or show symptoms such as pale skin, brittle nails, frequent headaches, unexplained shortness of breath, or rapid heartbeat. It is especially useful for individuals with a history of anaemia or other iron-related disorders, as well as those following vegetarian, vegan, or restrictive diets that may affect iron intake.
Why an Iron Status test matters
Iron is essential for healthy blood, energy and concentration — and both too little and too much can cause problems. Low iron is one of the most common causes of tiredness, particularly in women, while iron overload can quietly affect your organs over time.
This panel goes beyond a basic check, measuring five markers for a complete picture of your iron stores, transport and availability. It's especially useful for unexplained fatigue, heavy periods or simply feeling run down — and every result is reviewed and explained by a GP.
What's included in your Iron Status test
Five markers giving a complete picture of your iron.
Iron markers
- Serum Iron — measures the circulating iron in your blood.
- Ferritin — reflects your body's iron stores, helping to detect deficiency or overload.
- Total Iron-Binding Capacity (TIBC) — assesses the blood's capacity to transport iron.
- Transferrin — the protein responsible for carrying iron through the bloodstream.
- Transferrin Saturation — the proportion of transferrin bound to iron, giving a complete picture of iron availability.

What to know before your appointment
Book a morning appointment
Iron levels are naturally highest in the morning and fluctuate during the day, so a morning slot gives the most reliable result. You may also be asked to fast — we'll let you know when you book.
Pause iron supplements
If you take iron supplements, avoid them for at least 24 hours before your test (unless advised otherwise), as they can temporarily raise your serum iron and skew the result.
Stay hydrated
Please ensure you are well hydrated prior to your appointment, as being dehydrated may make the blood draw more difficult.
Biotin (Vitamin B7)
Biotin (Vitamin B7) is a common component of many multivitamins and is also available as a standalone supplement. Biotin is known to interfere with laboratory testing and can affect various blood results. Unless prescribed by your doctor, we recommend stopping supplementation at least 48 hours prior to testing. If the supplement has been prescribed, please speak with your doctor before stopping.
