About this test
The KnowYou+ Cell Blood Count Test measures four key areas of blood health: Haemoglobin (Hb), Red Blood Cell Count (RBC), White Blood Cell Count (WBC) and Platelets (PLT).
Together, these provide useful information about blood cells involved in carrying oxygen, supporting immune function and normal blood clotting.
The test can help provide insight into important blood-cell measurements, but the results must be considered alongside the customer's symptoms, medical history and any other relevant investigations.
This is a focused four-biomarker test and should not be described to customers as a comprehensive or full blood count.
What do the four biomarkers measure?
Haemoglobin (Hb)
Haemoglobin is the oxygen-carrying protein inside red blood cells. A reduced haemoglobin result may be relevant when investigating symptoms such as tiredness, weakness or breathlessness.
Red Blood Cell Count (RBC)
Measures the number of red blood cells in the blood. Red blood cells transport oxygen around the body.
White Blood Cell Count (WBC)
Measures white blood cells, which form an important part of the body's immune response.
Platelets (PLT)
Measures the number of platelets in the blood. Platelets play an important role in normal blood clotting.
Who might this test be suitable for?
Tiredness or low energy
A customer wants a basic assessment of haemoglobin and key blood-cell measurements as part of understanding persistent tiredness.
Previous blood-cell result
They have previously been told that haemoglobin or another blood-cell measurement was outside the expected range and want a current measurement.
General blood-cell insight
They specifically want information about red blood cells, white blood cells, haemoglobin and platelets.
Focused first check
They want a focused blood-cell test rather than a wider general-health or iron panel.
3 useful questions to ask
These questions help establish whether Cell Blood Count best matches the customer's question or whether another KnowYou+ test may provide more relevant information.
How to explain Cell Blood Count to the customer
Explain that the test measures haemoglobin, red blood cells, white blood cells and platelets.
It can provide useful information about these areas of blood health, but an individual result does not on its own diagnose the cause of symptoms or establish a medical condition.
Could another KnowYou+ test provide more relevant information?
| Customer wants to understand… | Test to consider |
|---|---|
| Haemoglobin and four key blood-cell measurements | Cell Blood Count |
| Stored iron specifically | Ferritin |
| A fuller picture of iron storage, transport and availability | Iron Status |
| Persistent tiredness with broader investigation of possible contributors | Fatigue & Tiredness |
| A broader overview across several areas of health | General Health |
Important to remember
A Cell Blood Count result is not a diagnosis.
The laboratory results provide measurements of haemoglobin, red blood cells, white blood cells and platelets.
Results outside the expected range can have many possible causes and should be interpreted in the context of symptoms, medical history and other clinical information.
Pharmacy staff should avoid diagnosing anaemia, infection, immune disorders or clotting conditions from these results alone.
When testing should not delay medical assessment
- Severe or rapidly worsening breathlessness
- Chest pain, fainting or marked weakness
- Significant or unexplained bleeding
- Black stools or vomiting blood
- Unusual or extensive unexplained bruising
- Persistent high fever or a customer who appears seriously unwell
- Persistent or worsening symptoms despite previous assessment
Urgent or concerning symptoms should be referred for appropriate medical assessment rather than relying on an at-home blood test. Full pharmacist referral guidance will be included in the training manual.
