Blood Count Test (4 Biomarkers) Haemoglobin, RBC, WBC & Platelets
This is an add-on test and must be purchased alongside an existing blood test order.
If purchased on its own, your order will be cancelled and refunded.
Monitor your fundamental health markers with our Blood Count Test. This test provides an essential overview of your blood health by assessing your red blood cells, white blood cells, and platelets. It can help identify signs of anaemia, infection, inflammation, immune system abnormalities, and issues affecting blood clotting, making it a valuable assessment of your overall health and wellbeing.
Frequently Asked Questions
| QUESTION | ANSWER |
|---|---|
|
Can you get a full blood count from a finger-prick test?
|
Please note that full blood count markers cannot all be obtained from home finger-prick samples, as certain parameters are less stable in capillary blood and require a in clinic venous blood draw for accurate measurement. The markers included in this test have been specifically selected because they can be reliably measured from a home finger-prick sample.
|
|
What do white blood cells tell us about my health?
|
White blood cells are the key cells of your immune system, responsible for defending your body against infection, bacteria, and viruses. This blood count test measures your total white blood cell count, giving you a direct indication of your immune system status. An abnormally high count can indicate an active infection or inflammation, while a low count may suggest a weakened immune system. Knowing your white blood cell levels is a useful baseline for understanding how well your body is currently equipped to fight off illness.
|
|
What symptoms suggest I should do a blood count test?
|
Persistent tiredness, weakness, shortness of breath, dizziness, pale skin, cold hands and feet, easy bruising, and difficulty concentrating can all point to abnormalities in your blood count. These symptoms are common and can have several causes, making a blood count test a straightforward and affordable first step toward understanding what is happening in your body.
|
|
What do platelets do and when should I get a platelet count test?
|
Platelets are small cell fragments that enable your blood to clot when you are injured. A low platelet count can cause easy bruising or prolonged bleeding, while an abnormally high count may increase the risk of unwanted clotting. A platelet count test is particularly useful if you bruise easily, are taking long-term medications, or want a baseline check of your blood health.
|
|
What causes a low red blood cell count?
|
A low red blood cell count is most commonly caused by iron deficiency, low vitamin B12 or folate levels, blood loss, or certain underlying health conditions. Red blood cells are responsible for transporting oxygen around the body, so a reduced count often presents as tiredness, low energy, and poor exercise tolerance. A red blood cell count test identifies whether your levels fall outside the normal range and helps guide next steps.
|
|
What is haemoglobin and why is it important?
|
Haemoglobin is the iron-rich protein inside your red blood cells that carries oxygen from your lungs to the rest of your body. Low haemoglobin is the most common indicator of anaemia and is frequently behind symptoms such as persistent fatigue, weakness, and shortness of breath. A home haemoglobin blood test is the most direct way to find out whether low oxygen delivery is affecting how you feel day to day.
|
|
What does this blood count test check?
|
Our blood count test measures key markers in your blood including haemoglobin, red blood cell count, white blood cells and platelets. Together these give a snapshot of your blood health, helping to identify signs of anaemia, assess your body's oxygen-carrying capacity, and evaluate your blood's ability to clot. It is one of the most commonly requested blood tests and a useful starting point for understanding your general health.
|
|
Why am I always tired?
|
Persistent 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.

Monitor your fundamental health markers with our Blood Count test. This test provides a vital snapshot of your blood health, helping to identify signs of anaemia, immune system status, and blood clotting capability.
What’s Included? This panel measures 4 essential biomarkers:
-
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.
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.
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.
Platelets: 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.
