CBC Test Overview

Complete blood count (CBC) evaluates cells circulating in blood i.e., red blood cells, white blood cells and platelets which determine  general state of heath of an individual.  CBC is useful in patients presenting with tiredness, screen for anaemias or to diagnose infection in those with fever. It is important basic test to state bone marrow and spleen functioning, diagnose blood cancers, and to monitor  blood disorders , chemotherapy and other medication

What is the CBC?

A CBC counts the cells in your blood. There are numerous reasons why your levels may be outside of the typical range. Abnormal amounts of RBCs, hemoglobin, or hematocrit, for example, may indicate anaemia, heart problems, or a lack of iron in your body. A CBC test can be used to help diagnose a variety of health issues. It can also be used to monitor how different diseases or medical treatments are working.

People with the following symptoms should do the CBC test:

The doctor may suggest a CBC test if a person experiencing symptoms like:

  • Weakness.
  • Fatigue.
  • Fever.
  • Inflammation.
  • Bruising.
  • Bleeding.

Frequently Asked Questions

CBC is done as a marker of general health, a basic investigation  to suggest further line of  testing or treatment. It is used to screen anaemia, determine type of anaemia and screen for Haemoglobinopathy
In cases of fever to know the extent and type of infection.
Presence of immature cells / blasts/ atypical cells in CBC can suggest leukemia/ lymphoma/ blood cancers and indicate further  bone marrow studies/ Immunophenotyping of cells.
Presence of increased or decreased platelet count can suggest urgent medical management / bone marrow study

A CBC also measures, analyses, and studies several aspects of blood:

  • CBC without differential counts the total amount of WBCs.
  • CBC with differential. The differential counts the number of each type of WBC in our body. WBCs are classified into five types.
  • Hemoglobin tests measure hemoglobin levels, the oxygen-carrying protein in RBCs.
  • Hematocrit describes the concentration of RBCs in our blood.

Red cell count – Total number of RBC in blood
Haemoglobin- Oxygen carrying capacity of blood 
Haematocrit- Proportion of blood volume that consists of RBC
Mean Corpuscular Volume (MCV) – Average size of RBC
Mean Corpuscular Haemoglobin (MCH) – Average Haemoglobin inside RBC
Mean Corpuscular Haemoglobin Concentration (MCHC) – How concentrated Haemoglobin is within RBC
Red Cell Distribution Width (RDW) – Variation in size of RBC
White blood cell count (TLC) – Number of leucocytes in blood
White Blood Cell Differential (DLC) – Relative number of neutrophils, lymphocytes, monocytes, eosinophils, basophils  
Platelet Count – The number of platelets (thrombocytes) in blood
Mean Platelet Volume (MPV) – Average volume of platelets
Platelet Distribution Width (PDW) – Variation in platelet size 

CBC test requires a blood sample. A tourniquet (elastic) band is placed tightly on the upper arm. The patient is then asked to make a fist. This helps in the build-up of blood filling the veins. The skin is disinfected before needle insertion and the blood sample is collected in vacutainer

This test requires a blood sample. A nurse or lab technician will draw a blood sample by inserting a needle into a vein in a person's arm. After that, a person can return to a normal schedule. They will send the blood to a laboratory to be examined.

Abnormal RBC Count – 
Low RBC count may be due to: Nutritional (Iron deficiency, Vitamin deficiency), chronic illness, blood loss, cancers of blood, bone marrow disorders, chemotherapy 
High RBC Count may be due to: dehydration, heart/Lung diseases, smoking, polycythaemia Vera, abnormal Haemoglobin and Haematocrit (PCV) usually mirrors RBC results
Low MCV indicates: Iron deficiency, thalassemia/Haemoglobinopthies 
High MCV indicates: Vitamin B12 or Folate deficiency, liver disease, hypothyroidism
Abnormal MCH and MCHC results usually mirror MCV results 
Low MCV and increased RBC count can suggest Thalassemia
Low RDW indicates uniformity in size of RBC; high RDW suggests: Iron deficiency anaemia, Pernicious anaemia
Abnormal Reticulocyte Count (RETIC):
Low RETIC count indicates: Bone marrow disorder, Nutritional deficiency
High RETIC count suggests: Bleeding, Haemolysis
Abnormal WBC count:
A low WBC count may suggest: Viral infection, Severe bacterial infection, Bone marrow disorders, Chemotherapy, Immunodeficiency, Auto immune disorders, Dietary deficiency, Reaction to drugs
A high WBC count suggests: Infection/inflammation, Allergies, Lymphoma, Leukaemia, Stress, Pregnancy, Corticosteroid treatment, Chronic infection
Abnormal platelet count-
Low platelet count may be in: Idiopathic Thrombocytopenic Purpura (ITP), Leukaemia, Lymphoma, Viral infections like dengue, Bacterial infections, Auto immune diseases, Chemotherapy/radiation therapy, Medications, Enlarged spleen
High platelet count may be in: Polycythaemia Vera, Essential Thrombocythemia (ET), Bone marrow disorders, Splenectomy, Anaemia, Infection
Abnormal MPV – 
A low MPV indicates: Bone marrow disorder
A high MPV suggests: Destruction of platelets and their rapid release from bone marrow into circulation
A low PDW suggests: Uniformity in size of platelets 
A high PDW indicates: Vascular diseases, Thyroid cancers
NOTE:- A peripheral blood smear examination may be done in case of abnormal CBC result  

A CBC usually does not require any particular preparation. However, if the doctor has requested further tests on a blood sample, the pateint may be required to fast (not eat or drink) for several hours prior to the test. 

Aside from leukemia, most cancers cannot be discovered with routine blood tests like a CBC. However, the findings can help healthcare providers in diagnosing cancer or determining whether cancer has spread.

Normal references ranges are:

  • WBC: 4,500--1,000 cells per microliter (cells/mcL)
  • RBC: 4.5--5.9 million cells/mcL for men; 4.1--5.1 million cells/mcL for women
  • Hemoglobin levels: From 14 to 17.5 gram per deciliter (gm/dL) in men and 12.3 to 15.3 gm/dL in women.
  • Hematocrit: From 41.5% to 50.4% in men and 35.9% to 44.6% in women.
  • Mean corpuscular volume (MCV): 80--96
  • Platelets: 150,000--450,000 platelets/mcL

High RBC and hemoglobin levels can be caused by:

  • Dehydration.
  • Heart or lung disease that reduces oxygen levels.
  • Certain kinds of kidney diseases.
  • Cigarette smoking.
  • Polycythemia vera, a rare disease causing overproduction of RBCs.

Low RBC, hemoglobin, or hematocrit levels indicate anemia, which can be caused by:

  • Blood loss.
  • Bone marrow failure.
  • Breakdown of RBCs (hemolysis).
  • Cancer and cancer treatment.

Nutritional deficiencies such as low iron, folate, or vitamin B12
