Complete blood count (CBC) is a common blood test often performed for people living with leukemia. If a CBC shows high or low numbers of any type of blood cell, this can help doctors better understand how your leukemia and any treatments for leukemia are affecting your body.
Full Answer
Leukemia is often discovered before symptoms arise when routine blood tests return abnormal results. Having abnormal levels of white blood cells, red blood cells, or platelets may indicate that a person has leukemia. In some types of leukemia, cancer cells may appear in the blood.
When someone has leukemia, their body makes larger, abnormal cells called leukemic cells instead of lymphocytes and other necessary cells like red blood cells (to carry oxygen) and platelets (to help blood to clot). This is why leukemia can cause symptoms like fatigue or excessive bleeding and bruising.
Many different types of blood tests can be used to diagnose leukemia and track your health and progress throughout treatment. Here are some of the most commonly used tests. A complete blood count (CBC) shows the current number of cells in your blood and what types of cells they are.
Leukemia—Patient Version. Health Professional Version. Leukemia is a broad term for cancers of the blood cells. The type of leukemia depends on the type of blood cell that becomes cancer and whether it grows quickly or slowly. Leukemia occurs most often in adults older than 55, but it is also the most common cancer in children younger than 15.
Your doctor will conduct a complete blood count (CBC) to determine if you have leukemia. This test may reveal if you have leukemic cells. Abnormal levels of white blood cells and abnormally low red blood cell or platelet counts can also indicate leukemia.
Blood tests. By looking at a sample of your blood, your doctor can determine if you have abnormal levels of red or white blood cells or platelets — which may suggest leukemia. A blood test may also show the presence of leukemia cells, though not all types of leukemia cause the leukemia cells to circulate in the blood.
At the time of diagnosis, patients can have very, very high white blood cell counts. 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.
Is leukocytosis a blood cancer? No. Leukocytosis refers to a high white blood cell count, which can occur for a number of reasons. Rarely, a high white blood cell count can be a symptom of certain blood cancers, such as acute myeloid leukemia, chronic myelogenous leukemia and chronic lymphocytic leukemia.
When you give a blood sample, it may be tested in the laboratory in many different ways. Common blood tests for leukemia include complete blood count (CBC), genetic analysis of cancer cells, and minimal residual disease (MRD) — a measurement of how many leukemia cells remain in the body after treatment.
Different types of leukemia can be indicated by different blood test results. Acute lymphocytic leukemia (ALL) may cause a large number of immature white cells (lymphoblasts) in the blood, as well as low numbers of red blood cells and platelets. Acute myeloid leukemia (AML) may cause pancytopenia.
5,000 to 10,000 for men. 4,500 to 11,000 for women. 5,000 to 10,000 for children. Normal ranges for hematocrit levels are: 42 percent to 54 percent of total blood count for men. 37 percent to 47 percent for women. 32 percent to 44 percent for children. Hemoglobin is expressed in grams per deciliter (gm/dL).
Hemoglobin indirectly measures the number of red blood cells in your blood. Hematocrit and hemoglobin help doctors better understand how well your RBCs are functioning at carrying oxygen to the tissues of your body.
Platelets are also referred to as thrombocytes. They are small cells that gather at sites of injury and help blood clot. Two other aspects of blood are usually tested in a CBC: hematocrit and hemoglobin. Hematocrit levels measure how much of your blood, by percentage, is currently made up of red cells.
It can also indicate dehydration. In rare cases, a high RBC count may be due to polycythemia vera, a type of blood cancer in which RBCs are overproduced by the bone marrow.
Also known as leukocytosis, a high WBC count is a hallmark of some types of leukemia and other cancers of the bone marrow. High white blood cell counts can also indicate an existing infection or a dysfunction in the immune system.
Leukemia mainly affects white blood cells called lymphocytes. These immune cells help your body fight off infections.
Typical blood cell counts vary by age and gender. They can also temporarily change depending on whether you recently had a bad flu, infection, or even injury. The healthy blood cell ranges are shown in the table below:
If you have higher than normal levels of white blood cells and low counts of red blood cells and platelets, the doctor will order additional tests atto get more information.
Your doctor will let you know how often you’ll need to return for more blood tests. If you are diagnosed with leukemia, you may need regular physical exams and blood tests, so your doctor can watch for signs of disease progression or remission.
Leukemia is a type of blood and bone marrow cancer. You may not notice symptoms for a long time, if at all. This is why a complete blood count test can help show imbalances in your blood cells.
Blood tests for leukemia may be used to diagnose cancer and to track your health and progress during treatment. These lab tests are sometimes used in conjunction with a bone marrow biopsy or bone marrow aspiration, in which a sample of the spongy tissue or fluid found in some bones is taken for laboratory analysis.
Blood tests are not only used to confirm a diagnosis of leukemia — they may also be used throughout leukemia treatment to give your doctors better insight into how your body is functioning and responding to treatment . This article describes what to expect when undergoing blood tests for leukemia.
Cytogenetic testing of leukemic cells analyzes changes to the chromosomes or genes. Cytogenetic testing is an important part of leukemia diagnosis. It can also be used to determine the best treatment approaches and monitor your response to treatments.
Leukemia and treatments for leukemia, such as chemotherapy and radiation, can affect circulating blood cell counts in various ways. A CBC can be used to help diagnose leukemia, track progress during treatment, and determine whether leukemia has spread (metastasized) to the bone marrow.
Mark Levin, M.D. Article written by. Victoria Menard. Leukemia is a cancer of the blood cells that begins in the bone marrow. It is often first diagnosed when routine blood tests show abnormal results. As one MyLeukemiaTeam member wrote, their chronic leukemia was diagnosed “through a regular yearly blood test.”.
This test looks for DNA specific to leukemia cells and can identify one cancer cell in 100,000 to 1 million normal cells. It may take several weeks to find out the results of this test.
Minimal residual disease (MRD) is a relatively new type of test used in blood cancers that can detect small numbers of cancer cells — even one malignant cell in 1 million normal cells — that may remain after leukemia treatment.
Your eyes, mouth and skin may also be examined. Your doctor may also be on the lookout for signs of infection and bruises, as frequent infections, widespread bruises and easy bleeding are associated with some types of leukemia.
For some types of leukemia, such as chronic lymphocytic leukemia, blood tests may be the only test needed to confirm the diagnosis (but other tests may be used to find out more about the cancer). To officially diagnose other types, such as acute lymphocytic leukemia, blood tests are typically followed by bone marrow tests.
Chronic lymphocytic leukemia (CLL): The blood of people with CLL contains high levels of lymphocytes (a type of white blood cell). Under a microscope, these cells don’t look like normal, healthy cells. The number of platelets and red blood cells may be low.
The findings associated with some of the main leukemia types are summarized below. Acute myeloid leukemia (AML): Blood tests of people with AML tend to reveal high levels of immature white blood cells and low levels of red blood cells and platelets.
When it’s used, however, it’s typically done because a lymph node has increased in size after diagnosis, raising concern that the cancer may have become more aggressive.
If you’re concerned you may have leukemia or are experiencing symptoms associated with leukemia, a physical exam is often the first method your doctor utilizes to see what’s going on. The physical exam may be focused on looking or feeling for swelling in the lymph nodes, liver and spleen.
The process may also reveal how much DNA is in cancer cells, which indicates whether the cancer is likely to grow quickly or slowly. Biopsy: A biopsy is used to determine the type of leukemia, the growth rate of the tumor, and whether the disease has spread. Common biopsy procedures for leukemia include:

NCI does not have PDQ evidence-based information about prevention of leukemia.
NCI does not have PDQ evidence-based information about screening for leukemia.
Clinical advances, research findings, and NCI programs that are leading to progress in treating leukemia.
The information in this section is meant to help you cope with the many issues and concerns that occur when you have cancer.
Normally, the DNA tells the cell to grow at a set rate and to die at a set time. In leukemia, the mutations tell the blood cells to continue growing and dividing. When this happens, blood cell production becomes out of control.
Leukemia symptoms are often vague and not specific. You may overlook early leukemia symptoms because they may resemble symptoms of the flu and other common illnesses. Sometimes leukemia is discovered during blood tests for some other condition.
Types of leukemia. The major types of leukemia are: Acute lymphocytic leukemia (ALL). This is the most common type of leukemia in young children. ALL can also occur in adults. Acute myelogenous leukemia (AML). AML is a common type of leukemia. It occurs in children and adults.
Leukemia is cancer of the body's blood-forming tissues, including the bone marrow and the lymphatic system. Many types of leukemia exist. Some forms of leukemia are more common in children. Other forms of leukemia occur mostly in adults. Leukemia usually involves the white blood cells.
How leukemia is classified. Doctors classify leukemia based on its speed of progression and the type of cells involved. The first type of classification is by how fast the leukemia progresses: Acute leukemia. In acute leukemia, the abnormal blood cells are immature blood cells (blasts).
The second type of classification is by type of white blood cell affected: Lymphocytic leukemia. This type of leukemia affects the lymphoid cells (lymphocytes), which form lymphoid or lymphatic tissue. Lymphatic tissue makes up your immune system. Myelogenous (my-uh-LOHJ-uh-nus) leukemia.
There are many types of chronic leukemias. Some produce too many cells and some cause too few cells to be produced. Chronic leukemia involve s more-mature blood cells . These blood cells replicate or accumulate more slowly and can function normally for a period of time.
A diagnosis of leukemia is usually made by analyzing a patient’s blood sample through a complete blood count (CBC) or microscopic evaluation of the blood, or by using flow cytometry. "Flow cytometry is a very sensitive technology that uses a laser beam to identify the very specific types of cells found in a sample," Dr. Siddon says.
Diagnosing leukemia in its earliest stages can improve a patient ’s prognosis, so it is important to be tested as soon as possible if leukemia is suspected.
Overview. Leukemia is cancer of bone marrow stem cells – immature cells that normally would develop into either red blood cells, white blood cells or platelets. When someone has leukemia, the bone marrow produces abnormal blood cells that do not die when they become old, as normal, healthy cells do. These abnormal cells build up in the bone marrow ...
Bone marrow testing is usually done in conjunction with blood tests because it adds information that can aid with diagnosis and treatment decisions. "For a bone marrow biopsy, a core of bone is removed with a long needle and the bone marrow is examined under a microscope.
In that case, flow cytometry may be performed on bone marrow (usually taken from the hip bone) or other tissue, such as a piece of a lymph node.
Leukemia that affects myeloid cells, which would normally develop into red blood cells, platelets or granulocytes (a specific type of white blood cell), is called myeloid leukemia or myelogenous or myeloblastic leukemia. Leukemia that affects lymphoid cells, which would develop into lymphocytes, is called lymphoid leukemia or lymphoblastic ...
