Complete blood count (CBC)
Blood cells, anaemia and selected infection clues
A complete blood count measures several parts of the blood, including red cells, white cells, platelets, haemoglobin, haematocrit and cell-size indices. It can support an assessment of anaemia, infection clues, bleeding concerns and treatment monitoring, but the result must be interpreted with your history and symptoms.
What does a complete blood count measure?
A CBC reports the number and selected characteristics of red blood cells, white blood cells and platelets. It commonly includes haemoglobin, haematocrit and red-cell indices; an ordered differential gives more detail about types of white blood cells. Confirm whether the quoted test includes a differential rather than assuming every CBC is identical.
Why might a CBC be requested?
A clinician may request a CBC during a general assessment or when investigating fatigue, weakness, fever, inflammation, bruising or bleeding. It may also monitor a known condition or treatment that affects blood cells. The CBC can reveal patterns that guide the next question, but it does not identify one diagnosis by itself.
Do you need to fast before a CBC?
A CBC by itself usually needs no special preparation. If it is collected with glucose, lipids or another test, the combined order may carry fasting or timing instructions. Confirm the full order, share medicines and supplements, and do not stop prescribed treatment unless your healthcare professional specifically tells you to.
How is the CBC sample collected?
A trained professional usually takes a small venous blood sample into a labelled tube after confirming your identity and order. Mention fainting, difficult veins, anticoagulants or persistent bleeding before collection. Ask how the sample will reach the laboratory and when the report is expected, especially for home collection.
How should CBC results be interpreted?
Read each result with the units and reference interval printed by that laboratory. A high or low cell count can have many causes, and the pattern across haemoglobin, cell indices, white-cell types and platelets is often more useful than one flag. A qualified professional should relate the report to symptoms, medicines and earlier results.
What should you confirm about CBC cost and reporting?
Ask for a written total rather than relying on a package title. The useful comparison states the exact CBC components, any collection or home-visit fee, the reporting window and whether clinical review costs extra. It should also explain who contacts you if the laboratory identifies a result needing prompt attention.
- Does the price include a white-cell differential and all collection fees?
- When and how will the complete report be delivered?
- Who can explain an unexpected or urgent result, and is that review included?
