What tests are in a CBC?
A CBC test usually includes:White blood cell (WBC, leukocyte) count. … White blood cell types (WBC differential). … Red blood cell (RBC) count. … Hematocrit (HCT, packed cell volume, PCV). … Hemoglobin (Hgb). … Red blood cell indices. … Platelet (thrombocyte) count. … Mean platelet volume (MPV).
What does a full blood test show?
Full blood count (FBC) This is a test to check the types and numbers of cells in your blood, including red blood cells, white blood cells and platelets. This can help give an indication of your general health, as well as provide important clues about certain health problems you may have.

Can CBC detect viral infection?
A CBC test usually includes: White blood cell (WBC, leukocyte) count. White blood cells protect the body against infection. If an infection develops, white blood cells attack and destroy the bacteria, virus, or other organism causing it.
How do you read a CBC?
What Does a CBC Measure?White blood cells (WBCs). These help your body fight germs. … Red blood cells (RBC). These deliver oxygen throughout your body. … Hemoglobin (Hb or Hgb). This is the protein in your blood that holds oxygen.Hematocrit (Hct). … Mean corpuscular volume (MCV). … Platelets.
What infections affect white blood cells?
Viral infections: Acute viral infections, such as colds and influenza may lead to temporary leukopenia. In the short term, a viral infection may disrupt the production of white blood cells in a person’s bone marrow. Blood cell and bone marrow conditions: These can lead to leukopenia.
