The most common leukemia biomarkers are CD (cluster of differentiation) markers, an extremely diverse series of membrane proteins predominantly expressed on the leukocyte surface. CD markers are mostly useful for classifying white blood cells (WBC) and especially important for diagnosis of lymphomas and leukemias.
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.
B-cell leukemia/lymphoma panel is a blood test that looks for certain proteins on the surface of white blood cells called B-lymphocytes. The proteins are markers that may help diagnose leukemia or lymphoma.
There are different types of tumor markers for different types of cancer. Certain tumor markers are associated with only 1 type of cancer. Other tumor markers are associated with more than 1 cancer. However, many cancers have no known tumor markers, so tumor marker testing may not be an option.
Tumour marker blood tests
Tumour markers are substances that might be raised if there is a cancer. They're usually proteins. They can be found in the blood, urine or body tissues. You might also hear them called biomarkers or molecular markers.
Normal range: < 2.5 ng/ml. Normal range may vary somewhat depending on the brand of assay used. Levels > 10 ng/ml suggest extensive disease and levels > 20 ng/ml suggest metastatic disease.
Tumor marker tests are not perfect. They are often not specific for cancer and may not be sensitive enough to pick up a cancer recurrence. The presence of tumor markers alone is not enough to diagnose cancer. You will probably need other tests to learn more about a possible cancer or recurrence.

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.
Common leukemia signs and symptoms include: Fever or chills. Persistent fatigue, weakness. Frequent or severe infections.
The white cells in the blood grow very quickly, over a matter of days to weeks. Sometimes a patient with acute leukemia has no symptoms or has normal blood work even a few weeks or months before the diagnosis. The change can be quite dramatic.
Stress hormones can inhibit a process called anoikis, which kills diseased cells and prevents them from spreading, Sood says. Chronic stress also increases the production of certain growth factors that increase your blood supply. This can speed the development of cancerous tumors, he adds.
CA 15-3 is a substance that stimulates your body's defense system. Some kinds of cancer cells release the CA 15-3 antigen into the blood. This test is used to monitor certain types of cancer. Breast cancer is the cancer most likely to release CA 15-3, especially in breast cancer that comes back after treatment.
An increase in tumour marker levels may mean the cancer is not responding to treatment, is growing or has come back (recurred). A slight increase may not be significant. The doctor looks at trends in the increase over time. Chemotherapy treatment can cause a temporary increase in tumour marker levels.
The cause of acute leukaemia is unknown, but factors that put some people at higher risk are: exposure to intense radiation. exposure to certain chemicals, such as benzene. viruses like the Human T-Cell leukaemia virus.
A tumor marker is anything present in or produced by cancer cells or other cells of the body in response to cancer or certain benign (noncancerous) conditions that provides information about a cancer, such as how aggressive it is, what kind of treatment it may respond to, or whether it is responding to treatment.
Although not produced by the leukemic cells themselves, an increased CA 125 serum level may indicate serosal involvement in leukemia patients with advanced disease.
Because CA-125 misses half of early cancers and can be elevated by benign conditions, such as diverticulitis, endometriosis, liver cirrhosis, pregnancy, and uterine fibroids, it is not used by itself to diagnose the disease, and the National Cancer Institute and the United States Preventive Services Task Force do not ...
There is also some evidence to suggest that stress may cause your body to generate increased CA-125. If you're experiencing any of the above health conditions, including high levels of stress, tell your doctor before having your test done.
