Blood Quizzes & Trivia

A complete blood count (CBC) is a blood test used to evaluate your overall health and detect a wide range of disorders. A complete blood count test measures several components and features of one’s blood such as the red and white blood cells. Take the quiz below and see how much you understand this concept.


Questions and Answers
  • 1. 

    Norm WBC range:

    • A.

      0.5-1

    • B.

      4.5-11

    • C.

      55-70

    Correct Answer
    B. 4.5-11
    Explanation
    The given answer, 4.5-11, represents the normal range for white blood cell (WBC) count in the body. WBCs are an important part of the immune system and help fight against infections and diseases. A WBC count between 4.5-11 is considered within the normal range, indicating a healthy immune response. This range ensures that the body has an adequate number of WBCs to defend against pathogens without being too high or too low, which could indicate an underlying health issue.

    Normal RBC range:

    • A.

      4.3-5.7

    • B.

      4.5-11

    • C.

      7.5-11.5

    Correct Answer
    A. 4.3-5.7
    Explanation
    The given answer, 4.3-5.7, represents the normal range for red blood cell (RBC) count. This means that a healthy individual should have a RBC count within this range. Values below or above this range may indicate an abnormality in the number of RBCs in the blood, which could be indicative of certain medical conditions.

  • 3. 

    Normal Hgb range:

    • A.

      13.2-17.3

    • B.

      4.5-11

    • C.

      0.5-1

    Correct Answer
    A. 13.2-17.3
    Explanation
    The given answer, 13.2-17.3, is the correct range for normal Hgb (hemoglobin) levels. Hemoglobin is a protein in red blood cells that carries oxygen throughout the body. The normal range for Hgb levels in adults is typically between 13.2 and 17.3 grams per deciliter (g/dL). This range may vary slightly depending on factors such as age, sex, and overall health. Hgb levels outside of this range may indicate anemia or other underlying medical conditions.

    Normal Hct range:

    • A.

      55-70

    • B.

      26-36

    • C.

      39-49

    Correct Answer
    C. 39-49
    Explanation
    The correct answer is 39-49. This is the normal range for hematocrit (Hct) levels in the blood. Hematocrit measures the percentage of red blood cells in the total blood volume. A Hct level between 39-49 indicates a healthy amount of red blood cells in the blood, which is important for oxygen transport and overall blood function. Hct levels below or above this range may indicate anemia or other underlying health conditions.

    Normal MCV range:

    • A.

      2-8

    • B.

      80-100

    • C.

      55-70

    Correct Answer
    B. 80-100
    Explanation
    The given MCV range of 80-100 is considered to be normal. MCV stands for Mean Corpuscular Volume, which measures the average size of red blood cells. This range indicates that the red blood cells are within the expected size range, suggesting a healthy blood cell population. Values below or above this range may indicate certain medical conditions or abnormalities in the red blood cells.

    Normal MCH range:

    • A.

      39=49

    • B.

      80-100

    • C.

      26-36

    Correct Answer
    C. 26-36
    Explanation
    The given answer range of 26-36 is within the normal MCH range. MCH stands for Mean Corpuscular Hemoglobin, which measures the average amount of hemoglobin in red blood cells. A normal MCH range indicates that the amount of hemoglobin in the red blood cells is within the expected levels.

    Normal MCHC range:

    • A.

      80-100

    • B.

      26-36

    • C.

      31-37

    Correct Answer
    C. 31-37
    Explanation
    The correct answer is 31-37. The MCHC (mean corpuscular hemoglobin concentration) is a measurement of the average concentration of hemoglobin in red blood cells. A normal MCHC range is typically between 31-37 grams per deciliter (g/dL). This range indicates that the red blood cells have a normal amount of hemoglobin, which is necessary for oxygen transport in the body. Values below or above this range may indicate certain medical conditions or abnormalities in the red blood cells.

    Normal RDW range:

    • A.

      11-15

    • B.

      2-8

    • C.

      55-70

    Correct Answer
    A. 11-15
    Explanation
    The given answer, 11-15, is the correct range for normal RDW (Red Cell Distribution Width) levels. RDW is a measure of the variation in red blood cell size. A normal RDW range of 11-15 indicates that the red blood cells are relatively uniform in size, which is considered healthy. If the RDW level falls outside this range, it may suggest certain medical conditions such as anemia or nutritional deficiencies.

    Normal Platelet range:

    • A.

      150-400

    • B.

      80-100

    • C.

      7.5-11.5

    Correct Answer
    A. 150-400
    Explanation
    The normal platelet range is typically between 150-400. This range represents the normal levels of platelets in the blood, which are important for clotting and preventing excessive bleeding. Platelet counts below or above this range may indicate certain medical conditions or disorders, such as thrombocytopenia or thrombocytosis. Therefore, it is important to monitor platelet levels to ensure they fall within the normal range for optimal health.

    Normal MPV range:

    • A.

      7.5-11.5

    • B.

      55-70

    • C.

      20-40

    Correct Answer
    A. 7.5-11.5
    Explanation
    The normal MPV range is 7.5-11.5. MPV stands for Mean Platelet Volume, which is a measure of the average size of platelets in the blood. Platelets are important for blood clotting, and abnormalities in their size can indicate certain health conditions. The given range suggests that a normal MPV value falls within this range, indicating that the platelets are of an appropriate size.

    Normal neutrophil range:

    • A.

      0.4-1

    • B.

      20-40

    • C.

      55-70

    Correct Answer
    C. 55-70
    Explanation
    The normal neutrophil range is 55-70. Neutrophils are a type of white blood cell that helps the body fight off infections. Having a higher number of neutrophils within this range indicates a healthy immune system. Neutrophil levels below 55 may indicate a weakened immune system, while levels above 70 may suggest an infection or inflammation.

    Normal lymphocyte range:

    • A.

      20-40

    • B.

      2-8

    • C.

      80-100

    Correct Answer
    A. 20-40
    Explanation
    The normal lymphocyte range is typically between 20-40%. This means that in a blood sample, lymphocytes should make up around 20-40% of the total white blood cell count. Lymphocytes are an important type of white blood cell that play a crucial role in the immune response. Any values below or above this range may indicate an abnormality in the immune system.

    Normal monocyte range:

    • A.

      0-4

    • B.

      2-8

    • C.

      0.5-1

    Correct Answer
    B. 2-8
    Explanation
    The correct answer is 2-8. This range indicates the normal levels of monocytes in the blood. Monocytes are a type of white blood cell that play a role in the immune response. Having a range of 2-8 suggests that a healthy individual should have between 2 to 8 monocytes per microliter of blood.

    Normal eosonophil range:

    • A.

      2-8

    • B.

      0-4

    • C.

      0.5-1

    Correct Answer
    B. 0-4
    Explanation
    The normal eosinophil range is 0-4. Eosinophils are a type of white blood cell that are involved in the immune response against parasitic infections and allergic reactions. A higher eosinophil count may indicate an allergic reaction or a parasitic infection, while a lower count may be seen in certain types of bone marrow disorders or autoimmune diseases. Therefore, a range of 0-4 is considered normal for eosinophil levels in the blood.

  • 15. 

    Normal basophil range:

    • A.

      0.5-1

    • B.

      0-4

    • C.

      2-8

    Correct Answer
    A. 0.5-1
    Explanation
    The normal basophil range is typically between 0.5-1. This means that in a healthy individual, the percentage of basophils in the blood should fall within this range. Basophils are a type of white blood cell that play a role in the immune response and allergic reactions. If the basophil count is below or above this range, it may indicate an underlying medical condition or disorder.
