Complete Blood Count (CBC)

CBC or complete blood count quantify a numbers of components and hallmark of our blood. Following function of blood listed below:

  • RBCs take oxygen to whole human body.
  • WBCs fight against different infection.
  • Hemoglobin, the oxygen taking protein in RBCs.
  • Hematocrit (Hct), the portion of RBCs to the fluid component, or plasma, in our blood.
  • Platelets, they help us by clotting our blood during bleeding.

During cell count abnormal clotting counts may raise or reduce as disclose which tell us that you have an underlying/latent medical condition that tell us about assessment about human body.

Red Blood Cells (RBC)

RBCs take oxygen from lungs and deliver to the rest of the human body, and bring back carbon dioxide to the lungs.

  • Low = Anemia
  • High = Polycythemia


In nature hemoglobin is basically a protein, which takes oxygen to different body’s organs and human tissues. Bring back deoxygenated blood from organs and tissues back to the lungs. Hemoglobin test estimate the amount of hemoglobin in our blood

During CBC analysis if the indication showing that hemoglobin level is lower than normal range that clearly means that we have a decrease level of RBCs (anemia).

Anemia have numbers of agents such as vitamins deficiency, bleeding disorder and chronic case of diseases.

Red Blood Cells Indices

  • MCV- mean corpuscular volume
  • MCH- mean corpuscular hemoglobin
  • MCHC- mean corpuscular hemoglobin concentration

They help us in the diagnose of specific types of anemia.

White Blood Cells (WBC)

White blood cells (WBCs) help us to fight against infections. They are also known as leukocytes (WBCs). We classify WBCs into 5 major types which tell us more detailed about different types of infection.

  • Neutrophils
  • Eosinophils
  • Lymphocytes (T cells and B cells)
  • Monocytes
  • Basophils

Hematocrit (HCT)

Hematocrit is a test that quantify the exact percentage (%) of whole blood which is made up of RBCs. This quantification relay on the size of RBCs and the number of RBCs.

Normal ranges:

May vary according to gender,

  • Male: 40.7 – 50.3%
  • Female: 36.1 – 44.3%


A platelet count test quantify the level in the human body or how many platelets we have in our blood. Platelets help us in the clotting mechanism. They are smaller than RBCs and WBCs.

Normal Ranges:

150,000 – 400,000 (mcL).

The condition which describe the presence of abnormally low level than normal numbers of platelets in our blood is known thrombocytopenia, which can be seen in following condition:

  • Cancer chemotherapy
  • Certain medications
  • Disseminated intravascular coagulation (DIC)
  • Hemolytic anemia
  • Idiopathic thrombocytopenic purpura (ITP)
  • Leukemia
