Full Blood Count (FBC) Test – At-Home Blood Health Check

Quick Overview

A Full Blood Count (FBC) test is one of the most common and informative blood tests available. It measures the levels of red blood cells, white blood cells, haemoglobin, haematocrit, and platelets in your blood. By assessing these components, the test provides valuable insight into your overall health, immune function, and potential underlying conditions such as anaemia, infection, inflammation, or blood disorders.

Our at-home Full Blood Count test kit makes it easy to check your blood health without waiting for GP appointments. Simply order online, take a small blood sample from home, send it to our accredited UK laboratory, and receive your secure digital results—typically within 1–2 working days.

What Is a Full Blood Count Test?

A Full Blood Count (sometimes called Complete Blood Count, or CBC) is a standard diagnostic test that evaluates the cells circulating in your bloodstream.

It measures:

• Red Blood Cells (RBCs): Carry oxygen around the body.

• Haemoglobin (Hb): The oxygen-carrying protein inside red blood cells.

• Haematocrit (Hct): The proportion of blood made up of red blood cells.

• White Blood Cells (WBCs): Essential for immune defence against infections.

• Differential WBC Count: Breaks down the different types of white blood cells (neutrophils, lymphocytes, monocytes, eosinophils, basophils).

• Platelets (thrombocytes): Help your blood clot and stop bleeding.

• Mean Cell Volume (MCV), Mean Cell Haemoglobin (MCH), Mean Cell Haemoglobin Concentration (MCHC): Indicators of red blood cell size and haemoglobin content.

Because these markers reflect so many aspects of your health, doctors often describe the FBC as a “window into your body’s wellbeing.”

Why Take a Full Blood Count Test?

An FBC is a broad health check that can highlight a wide range of issues. You may benefit from testing if you:

• Feel tired, weak, or fatigued without clear reason.

• Experience frequent infections or find it hard to recover.

• Have pale skin, dizziness, or shortness of breath (possible signs of anaemia).

• Notice unusual bruising or bleeding (may relate to platelet levels).

• Have a known condition that requires ongoing monitoring (e.g. inflammatory disorders, chronic infections, or blood disorders).

• Want a baseline health check as part of routine wellness monitoring.

It can also help detect:

• Anaemia (low red blood cells or haemoglobin).

• Iron, vitamin B12, or folate deficiency.

• Infections (bacterial or viral).

• Inflammation or immune system disorders.

• Blood cancers such as leukaemia (when combined with other investigations).

• Platelet problems (too high or too low).

Who Should Consider This Test?

The Full Blood Count test is suitable for most adults who want to gain insight into their health. It is particularly useful for:

• People with persistent tiredness or low energy.

• Individuals with a family history of blood or immune disorders.

• Those on long-term medication that may affect blood cells.

• Patients with chronic illness who require monitoring.

• Anyone seeking reassurance as part of a comprehensive health check-up.

What Your Results Will Show

Your Full Blood Count results will provide detailed information about:

• Red Blood Cell Health: Identifying anaemia or other red cell abnormalities.

• Immune Function: Detecting signs of infection, inflammation, or immune imbalance.

• Platelet Count: Evaluating blood clotting ability.

• Overall Health Patterns: Helping spot issues that may require further investigation.

Each result is presented with reference ranges, so you can easily see whether your values fall within the normal limits.

What Happens If My Results Are Abnormal?

If your FBC results are outside the normal range, don’t panic—there are many possible explanations. For example, a raised white blood cell count may simply indicate a recent infection, while low haemoglobin could suggest iron deficiency.

If your results are abnormal, we recommend:

• Speaking with your GP or healthcare provider for further interpretation.

• Considering additional testing (iron studies, vitamin B12, folate, inflammatory markers).

• Following medical advice on treatment or lifestyle adjustments.

We also provide guidance on next steps if anything requires follow-up.

Important Information

For capillary (finger-prick) blood samples, the laboratory can only report the following parameters for quality control reasons:

• Haemoglobin
• Red blood cell count
• White blood cell count
• Platelet count

The following tests cannot be reported from a self-collected capillary sample:

• Haematocrit
• MCV, MCH, MCHC
• White blood cell differential (absolute neutrophil, lymphocyte, monocyte, eosinophil, basophil counts)

These parameters require a venous blood sample, which must be collected by a trained healthcare professional. A separate fee applies for venous collection, typically ranging from £54 to £150, depending on the provider. You can book an appointment conveniently through Phlebotomy Services or with any other suitable provider near you.
