A Full Blood Count (FBC) Blood Test measures the different types of cells in your blood, including red blood cells, white blood cells, and platelets. It provides an overview of your general health and is commonly used to investigate symptoms such as fatigue, infection, or unexplained illness.

An FBC may help identify signs of anaemia, infection, inflammation, blood disorders, or abnormalities affecting the production or function of blood cells. It is often one of the first tests requested during routine health assessments.

No. Fasting is not required for a Full Blood Count Blood Test. You can eat and drink normally before your appointment unless you have been advised otherwise.

Results are typically available within 24 hours following laboratory analysis, allowing prompt review of your blood health.

Red blood cells carry oxygen from the lungs to tissues throughout the body, while white blood cells are part of the immune system and help defend against infections and disease.

Platelets are small blood cells that help your blood clot after an injury. Abnormal platelet levels may increase the risk of excessive bleeding or unwanted blood clot formation.

The Erythrocyte Sedimentation Rate (ESR) is a general marker of inflammation. An elevated ESR may indicate inflammation somewhere in the body but does not identify the specific cause.

No. An FBC cannot diagnose a condition on its own. It provides important information about your blood cells that helps healthcare professionals decide whether further investigation is needed.

This test is suitable for adults wanting a general health assessment, those experiencing symptoms such as fatigue, recurrent infections, unexplained bruising, or anyone monitoring an existing medical condition.

The frequency depends on your health, medical history, and whether you’re monitoring an existing condition. Many people choose to include an FBC as part of an annual health screening, while others may require more regular testing based on clinical advice.
