CBC Test Explained: What a Complete Blood Count Reveals
A Complete Blood Count (CBC) is the most frequently ordered blood test. It gives a broad snapshot of your overall health in one go.
What it measures
- Haemoglobin & RBC — screens for anaemia.
- WBC count — signals infection or inflammation.
- Platelets — important for clotting.
When is a CBC useful?
For symptoms like persistent tiredness, frequent infections, unexplained bruising, or as part of a routine or pre-surgery checkup.
Understanding results
Values are compared against reference ranges printed on your report. A single out-of-range value isn't always a concern — your doctor interprets the full picture.
