Biomarkers

  1. Ferritin

    Measures the amount of iron safely stored in your body's cells (liver, spleen, and muscles) for future use. Because ferritin stores deplete before circulating iron levels drop, this is the single most important marker for catching iron deficiency early.

  2. White Blood Cell Count (WBC)

    These cells are the frontline soldiers of your immune system. Doctors check this number to look for hidden infections, autoimmune responses, or inflammation. If your WBC count is elevated, it usually means your immune system is working exactly as it should by actively fighting off an illness, reacting to an allergen, or helping your body recover from stress.

  3. Red Blood Cell Count (RBC)

    Think of red blood cells as the body's delivery trucks for oxygen. Measuring the total number of these cells provides a great baseline for your general blood health and energy levels. An abnormal count, whether too high or too low, can help doctors pinpoint the cause of persistent tiredness or point toward potential dietary deficiencies, such as a lack of iron or B vitamins.

  4. Haemoglobin (Hb)

    This is the crucial iron-rich protein inside your red blood cells that physically grabs onto oxygen from your lungs and carries it to the rest of your body. Checking these levels helps identify anaemia. If your haemoglobin is low, your organs and muscles aren't getting the oxygen they need to function properly, which is often the culprit behind feeling constantly exhausted, weak, or short of breath.

  5. Hematocrit (HCT)

    The proportion, by volume, of your blood that consists of red blood cells.

  6. Mean Corpuscular Volume (MCV)

    Measures the average size of your red blood cells. Abnormally large or small cells help determine the specific underlying cause of anaemia.

  7. Mean Corpuscular Haemoglobin (MCH)

    The average amount of oxygen-carrying haemoglobin present inside a single red blood cell.

  8. Mean Corpuscular Haemoglobin Concentration (MCHC)

    The average concentration (density) of haemoglobin within a specific volume of red blood cells. 

  9. Iron

    Measures the amount of iron currently circulating in your blood. While essential for daily energy and red blood cell production, this level naturally fluctuates depending on your recent diet.

  10. Platelets (PLT)

    These are tiny cell fragments whose main job is to rush to the site of an injury, stick together, and form scabs. They are entirely responsible for your blood's ability to clot. Evaluating your platelets ensures your body can safely stop itself from bleeding; a low count might explain why you bruise very easily, while an abnormally high count could increase the risk of unwanted internal clots.

Frequently Asked Questions

QUESTION ANSWER
QCan a blood test show iron deficiency anaemia?
AYes. A ferritin blood test measures your body's iron stores, while a full blood count checks red blood cell count, haemoglobin, and other markers affected by iron deficiency. Together, these two tests can identify iron deficiency and anaemia before symptoms become severe.
QWhat is the difference between low ferritin and anaemia?
AFerritin measures your stored iron levels, while anaemia refers to a reduction in red blood cells or haemoglobin that affects the blood's ability to carry oxygen. You can have low ferritin without being formally anaemic, but low ferritin is often an early warning sign that anaemia may develop if left unaddressed. Testing both together gives the most complete picture.
QWhy am I always tired?
APersistent fatigue is one of the most common symptoms of low ferritin and iron deficiency. Other signs include weakness, reduced exercise tolerance, difficulty concentrating, and feeling cold.

Turnaround Time

Turnaround Time

Once your sample is collected and posted, it is processed in our laboratory with a typical turnaround time of 1-3 days from the moment the lab receives the kit.

Test Preparation

  • Ferritin and Blood Cell Count

    Fasting is not required for a ferritin test and blood cell count test, as levels are not significantly affected by recent meals. However, you should avoid fatty meals at least 6 hours before collecting your sample.

    The most important consideration is recent illness or infection. Ferritin is an acute-phase protein, meaning levels can rise significantly in response to inflammation or infection, even a mild cold. To avoid a falsely elevated result, wait until you have fully recovered before collecting your sample.

Symptom Check

  • Fatigue

    Low ferritin and abnormalities in the blood count may be associated with iron deficiency and anaemia. Symptoms can include persistent tiredness, weakness, reduced exercise tolerance, shortness of breath, dizziness, headaches, pale skin, cold hands and feet, poor concentration, brittle nails, and increased hair shedding.

Private Fatigue & Tiredness Blood Test Kit (10 Biomarkers)

Monitor your energy levels and overall health with our comprehensive, private At-Home Iron and Ferritin Blood Test Kit. Whether you are experiencing unexplained fatigue, brain fog, or persistent hair loss, checking your full blood count (FBC) and iron profile provides vital, clinical-grade insights into how your body is performing.

This test is specifically engineered for anyone dealing with "Tired All The Time" (TATT) symptoms, fitness enthusiasts struggling with exercise recovery, or vegans and vegetarians wanting to proactively monitor dietary deficiencies. Routine testing offers a reliable baseline to measure changes, identify your risk of anaemia or iron overload, and track trends over time.

Who Should Take an Iron & Ferritin Blood Test?

  • Individuals with Low Energy: People experiencing chronic exhaustion, weakness, brain fog, or unexplained muscle aches.
  • Vegans & Vegetarians: Proactively check for dietary iron deficiencies and safeguard your long-term wellness.
  • Athletes & Active Individuals: Ensure optimal oxygen delivery to tissues to support endurance, power output, and physical recovery.
  • Women's Health: Monitor iron depletion caused by heavy periods, pregnancy, or hormonal shifts.

How to Prepare & Take Your At-Home Iron Test

  1. Take the Test in the Morning: Iron levels naturally fluctuate throughout the day. Collect your sample early (before 10:00 AM) for maximum accuracy.
  2. Fast Overnight: Fast for 8 to 10 hours (water allowed) prior to collection, as recent meals can temporarily spike circulating iron levels.
  3. Stay Well-Hydrated: Drink plenty of water before taking your test to encourage blood flow for an easy finger-prick sample.
  4. Pause Iron Supplements: Pause taking iron supplements 24 to 48 hours prior to your sample collection (unless advised otherwise by your GP) to ensure a true baseline reading.

Common Symptoms of Low Iron & Anaemia

While iron deficiencies can develop without noticeable early symptoms, common warning signs include:

  • Persistent fatigue, tiredness, or weakness
  • Pale skin or cold hands and feet
  • Shortness of breath during normal daily activities or workouts
  • Frequent headaches or brain fog
  • Brittle nails, hair thinning, or hair loss

Frequently Asked Questions

Do I need to fast before an iron blood test?

Yes, you should fast (consuming only water) for 8 to 10 hours before taking your sample. Recent meals can temporarily increase circulating iron in your bloodstream and skew your results.

What is the difference between iron and ferritin?

Iron measures the active amount of mineral circulating in your blood at that exact moment. Ferritin measures the total stored iron reserved in your tissues. Ferritin drops first during deficiency, making it the best early indicator of low iron reserves.

Why must I collect my sample in the morning?

Iron concentrations follow a daily rhythm, fluctuating naturally throughout the day. Taking your sample before 10:00 AM after fasting provides the most consistent and medically accurate baseline.

How quickly will I receive my lab results?

Once your finger-prick sample reaches our accredited UK laboratory, your sample will be processed and reviewed by a doctor. Your confidential results will be uploaded to your secure digital dashboard within 2 to 3 working days.
