A complete blood picture (CBP) is a comprehensive test that gives an overview of the different components present in a person's blood. It is a basic and one of the most commonly ordered blood tests that provides important information about a person's overall health.

A CBP test measures different parameters such as red blood cells (RBCs), white blood cells (WBCs), platelets, hemoglobin, hematocrit, and mean corpuscular volume (MCV). These parameters give important insights into various health conditions such as anemia, infections, bleeding disorders, and various other blood-related diseases.

Red blood cells are responsible for carrying oxygen to different parts of the body. A low RBC count may indicate anemia, which can be caused by several factors such as iron deficiency, vitamin B12 deficiency, or kidney disease.

White blood cells are an essential part of the immune system, and they help fight against infections. An increase in WBC count can indicate an ongoing infection or inflammation in the body, while a decrease in WBC count can indicate a weakened immune system, making the person more susceptible to infections.

Platelets are small blood cells that help in clotting of blood. A low platelet count can lead to excessive bleeding and bruising, while an increase in platelet count can indicate a bleeding disorder or cancer.

Hemoglobin is the protein in red blood cells that carries oxygen. A low hemoglobin level may indicate anemia, while a high level may indicate dehydration or a genetic condition called polycythemia.

Hematocrit is the percentage of red blood cells in the blood. It gives an idea of the number of red blood cells in a person's blood and helps in determining anemia.

Mean corpuscular volume (MCV) is the average size of red blood cells. An increase in MCV can indicate a vitamin B12 or folate deficiency, while a decrease in MCV can indicate an iron deficiency.


In conclusion, a complete blood picture is a crucial test that helps diagnose various health conditions and diseases related to the blood. It is a simple test that provides a lot of information about a person's overall health and can help in early diagnosis and treatment of various health problems.
