CBC Test Explained: What Your Complete Blood Count Reveals

A Complete Blood Count (CBC) is one of the most commonly ordered lab tests — and for good reason. It gives a snapshot of your overall health through three main components: red blood cells, white blood cells, and platelets. Haemoglobin levels below normal range may indicate anaemia, often caused by iron deficiency. An elevated white blood cell count can signal infection or inflammation, while low platelet counts may affect your blood's ability to clot properly. If your CBC report shows values outside the normal range, don't panic — many factors including hydration, recent illness, and time of day can cause temporary fluctuations. Always discuss results with your doctor for proper interpretation.
