People with CLL may also have a high or low white blood cell count. Because their bone marrow
Bone marrow
Bone marrow is a semi-solid tissue which may be found within the spongy or cancellous portions of bones. In birds and mammals, bone marrow is the primary site of new blood cell production or hematopoiesis. It is composed of hematopoietic cells, marrow adipose tissue, and supportive stromal cells. In adult humans, bone marrow is primarily located in the ribs, vertebrae, sternum, and bones of the pe…
What causes low RBC count in CLL?
MONTHLY QUIZ: Anemia (low red blood cell (RBC) count) is a common complication in CLL. All of the following causes are directly related to CLL or its treatment except: Crowding in the bone marrow by the CLL cancer cells so there is not enough room left to make red blood cells.
What causes low white blood cell count?
Certain disorders present at birth (congenital) that involve diminished bone marrow function. Cancer or other diseases that damage bone marrow. Autoimmune disorders that destroy white blood cells or bone marrow cells. Severe infections that use up white blood cells faster than they can be produced.
What causes low platelets in CLL patients?
Less often, the antibodies attack platelets and the cells that make them, leading to low platelet counts. Rarely, the antibodies attack white blood cells, leading to leukopenia (low white blood cell counts). These symptoms and signs may be caused by CLL, but they can also be caused by other conditions.
Does leukemia affect WBC counts?
Leukemia and cancer treatments often have an impact on blood counts in general, including red blood cells and hemoglobin, and on platelets. It’s important for doctors to track WBC counts in a person living with leukemia or undergoing treatment for leukemia.
What does CLL do to white blood cells?
CLL is one of a group of diseases that affects a type of white blood cell called a "lymphocyte." Normally, lymphocytes help your body fight infection; however, in CLL, the body produces abnormal lymphocytes that cannot do this effectively. This leads to problems over time.
What type of leukemia causes low white blood cells?
Many signs and symptoms of AML are the result of a shortage of normal blood cells, which happens when the leukemia cells crowd out the normal blood-making cells in the bone marrow. As a result, people don't have enough normal red blood cells, white blood cells, and blood platelets.
What is the white count in CLL?
A normal lymphocyte range for adults is anywhere between 1,000 and 4,800 cells in 1 microliter (μl) of blood. A diagnosis of chronic lymphocytic leukemia requires a lymphocyte level of greater than or equal to 5,000 B cells per μl for a minimum of 3 months.
How low does white blood cell count have to be for leukemia?
Typically a healthy person has a white blood cell count of about 4,000-11,000. Patients with acute or even chronic leukemia may come in with a white blood cell count up into the 100,000-400,000 range.
What is the most common reason for low white blood cell count?
A low white blood cell count usually is caused by: Viral infections that temporarily disrupt the work of bone marrow. Certain disorders present at birth (congenital) that involve diminished bone marrow function. Cancer or other diseases that damage bone marrow.

What labs are abnormal with CLL?
People with CLL have too many lymphocytes. (This may be called lymphocytosis.) Having more than 10,000 lymphocytes/mm³ (per cubic millimeter) of blood strongly suggests CLL, but other tests are needed to know for sure. You might also have low levels of red blood cells and platelets.

What does it mean when your blood count is low?
When you visit your doctor for a check-up, your laboratory tests may come back with lower numbers of red blood cells or platelets. A low red blood cell count is known as anemia, and a low platelet count is called thrombocytopenia.
The Role of White Blood Cells
White blood cells are manufactured by the bone marrow, the spongy tissue found in the center of some of the larger bones in your body. Under normal conditions, a person’s bone marrow produces plenty of stem cells that develop into the various WBCs. There are five primary types of white blood cells:
High vs. Low White Blood Cell Counts in Leukemia
It’s important for doctors to track WBC counts in a person living with leukemia or undergoing treatment for leukemia. A low WBC or a high WBC count can provide important information for a doctor, helping them to interpret symptoms and achieve good treatment outcomes.
Other Conditions That May Cause Low WBC Counts
Having a low or high WBC is not always an indication of leukemia. Five percent of people will experience a high or low WBC in their lifetime. In fact, several noncancerous conditions can lead to an abnormal WBC count.
How To Avoid Infections
A person with leukemia is susceptible to foreign pathogens (viruses, bacteria, and allergens) and less equipped to fight off and heal from infections. This is especially true for a person undergoing chemotherapy as part of their treatment.

If you have leukemia, it can help to have the support of others who understand. MyLeukemiaTeam is the social network for people with leukemia and their loved ones. More than 9,000 members come together to ask questions, give advice, and share their experiences with others who understand life with leukemia.

Why do people with CLL have high white blood cells?
People with CLL may have very high white blood cell counts because of excess numbers of lymphocytes ( lymphocytosis ), but the leukemia cells don't fight infection the way normal white blood cells do. A shortage of blood platelets ( thrombocytopenia) can lead to excess bruising, bleeding, frequent or severe nosebleeds, and bleeding gums.
Why do people with CLL have a higher risk of infection?
