Meaning of Complete Blood Count Test
CBC test means complete blood count test. This is a test that measures all the characteristics of the cells in the blood. It comprises testing levels of red blood cells (RBCs), white blood cells (WBCs), and platelets. CBC test also measures the characteristics of the cells like haemoglobin (Hb) concentration and help in calculating other related values like haematocrit, mean corpuscular volume (MCV), Mean corpuscular haemoglobin concentration (MCHC).

Understanding the CBC Test Report
1. Red blood cell count:

Lower than normal value suggests either insufficient production or faster destruction. Reduced red cell production may be because of depressed bone marrow or insufficient supply of material needed to produce new cells like protein and iron deficiency. It suggests anaemia Higher than normal count suggests polycythaemia and thicker blood. It means the bone marrow is working in overdrive.

2. White blood cell count:

Lower levels suggest reduced immunity, bone marrow suppression

Higher values suggest infection, allergies, or bone marrow dysfunction.

3. Platelet count:

Lower value suggests bleeding tendencies, easy bruising, bone marrow suppression

Higher value suggests increased chances of internal clotting.

4. Blood Indices:

Lower than normal values of blood indices suggest anaemia, bone marrow suppression, or iron deficiency whereas higher than normal values suggest thick blood, vitamin B12 deficiency, dehydration.
