FBC Blood Test
FBC Blood Test
The FBC Blood Test, or Full Blood Count, is one of the most commonly requested and informative diagnostic tests in modern healthcare. It provides a detailed overview of the cells that circulate in your blood—including red blood cells, white blood cells, and platelets—offering essential insights into your overall health. An FBC can help detect a wide range of medical conditions, from infections and anaemia to immune system disorders, inflammation, and even certain cancers such as leukaemia.
This test is often used as a first-line health screening tool, whether you're experiencing fatigue, weakness, unusual bruising, or just seeking a general health check. According to the National Institute for Health and Care Excellence (NICE) and research from University College London (UCL), routine FBC testing plays a key role in early diagnosis and long-term disease monitoring. It is commonly used by GPs, hospital clinicians, and occupational health professionals to spot subtle imbalances that may not yet cause symptoms but indicate underlying health issues.
Whether for routine monitoring or to investigate specific symptoms, the FBC Blood Test is a valuable and versatile tool that supports accurate diagnosis and early intervention—empowering you and your healthcare provider to take a proactive approach to your wellbeing.
What Does This Test For?
This Full Blood Count (FBC) test evaluates key components of your blood, including red and white blood cells, haemoglobin, platelets, and markers related to cell size and oxygen-carrying capacity. It helps identify a wide range of health issues such as different types of anaemia, infections, inflammation, immune system abnormalities, and certain blood cancers. By measuring markers like haemoglobin, haematocrit, MCV, and MCH, the test assesses how well your red blood cells transport oxygen. White cell counts—including neutrophils, eosinophils, basophils, monocytes, and total WBC—offer insight into your immune response and can flag infections or more serious haematological conditions. Platelet count helps evaluate clotting function. Together, these biomarkers provide a comprehensive overview of your blood health and are often used to investigate symptoms such as fatigue, weakness, recurrent infections, or unexplained bruising.
