Can leukemia be detected in a blood test?

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.


What blood test indicates leukemia?

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.

What are the six signs of leukemia?

Common leukemia signs and symptoms include:
  • Fever or chills.
  • Persistent fatigue, weakness.
  • Frequent or severe infections.
  • Losing weight without trying.
  • Swollen lymph nodes, enlarged liver or spleen.
  • Easy bleeding or bruising.
  • Recurrent nosebleeds.
  • Tiny red spots in your skin (petechiae)


How soon does leukemia show up in blood work?

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.

Can leukemia be missed in a blood test?

In some cases, your doctor might order bone marrow testing even though your blood tests didn't indicate leukemia. That's because in some types of leukemia, cancer cells stay in the bone marrow and don't circulate in the blood.


Looking for Cancer in a Blood Test



What does leukemia look like on a blood test?

Understanding your blood count test results

If you have leukemia, your blood cells count will likely show higher than usual levels of white blood cells, which include leukemic cells. You may also have lower than usual red blood cell and platelet cell counts. If all three types are low, this is known as pancytopenia.

Does leukemia always show up in a CBC?

CBC is the most useful initial laboratory test in patients suspected of having leukemia. Most patients will show some abnormality in the CBC and some blasts will be seen in the peripheral smear in patients with acute leukemias. To diagnose CLL, a lymphocytosis of greater than 5000/mm3 must be present.

How can I test myself for leukemia?

There are currently no at-home tests that a person may use to aid leukemia diagnosis. If an individual has concerns about their health, they should contact a doctor as soon as possible.


What diseases mimic leukemia?

Leukemia is commonly misdiagnosed as the following conditions:
  • Influenza.
  • Fever.
  • Pathological fracture.
  • Bleeding disorders.
  • Immune thrombocytopenic purpura.
  • Trypanosomiasis.
  • Autoimmune lymphoproliferative syndrome.


Can you have leukemia with a normal white blood count?

These patients often have relatively normal blood cell counts and a lower incidence of organomegaly. This form of presentation can lead to delays in the diagnosis of acute leukemia in adults. We experienced the case of a 41‐year‐old male with acute leukemia presenting as bone pain with a normal white blood cell count.

Is leukemia hard to detect?

Because many types of leukemia show no obvious symptoms early in the disease, leukemia may be diagnosed incidentally during a physical exam or as a result of routine blood testing.


How do doctors rule out leukemia?

Laboratory tests, and specifically blood tests, are among the most important diagnostic tools for 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).

Are there any early detection signs of leukemia?

Unlike symptoms of the flu, which generally subside as you get better, leukemia symptoms generally last longer than two weeks, and may include sudden weight loss, bone and joint pain and easy bleeding or bruising. Other early warning signs of leukemia include: Fever, chills. Fatigue, weakness.

Can you have leukemia for years without knowing?

In CLL, the leukemia cells grow out of control and crowd out normal blood cells. These cells often build up slowly over time. Many people don't have any symptoms for at least a few years. In time, the cells can spread to other parts of the body, including the lymph nodes, liver, and spleen.


When should you suspect leukemia?

"A patient may be tested for leukemia if he or she has unexplained weight loss, night sweats or fatigue, or if he or she bruises or bleeds easily," Dr. Siddon says. "Sometimes routine blood work shows an unexplained elevated number of white blood cells."

Where does leukemia usually begin?

Leukemia starts in the soft, inner part of the bones (bone marrow), but often moves quickly into the blood. It can then spread to other parts of the body, such as the lymph nodes, spleen, liver, central nervous system and other organs.

What is the first stage of leukemia?

Stage 1 – A patient has high levels of white blood cells and enlarged lymph nodes. Stage 2 – A patient has high levels of white blood cells and is anemic. He or she may also have enlarged lymph nodes. Stage 3 – A patient has high levels of white blood cells and is anemic.


Can you feel fine and have leukemia?

Chronic leukemia often causes only a few symptoms or none at all. Signs and symptoms usually develop gradually. People with a chronic leukemia often complain that they just do not feel well.

What autoimmune disease is similar to leukemia?

Immune dysregulation, a hallmark of chronic lymphocytic leukemia (CLL), manifests itself in three autoimmune diseases: warm autoimmune hemolytic anemia (AIHA); idiopathic thrombocytopenia (ITP); and, pure red cell aplasia (PRCA).

What blood disorders come before leukemia?

Myelodysplastic syndrome (MDS) used to be known as “pre-leukemia,” or sometimes “smoldering leukemia.” MDS is a group of blood disorders that can cause you to have low levels of: red blood cells. white blood cells. platelets.


What is the survival rate of leukemia?

In the United States, overall, 5-year survival among people diagnosed with leukemia is 65%. However, these statistics vary greatly according to the specific subtype of disease: Chronic lymphocytic leukemia (CLL) 5-year survival rate is 85.4%. Acute lymphocytic leukemia (ALL) 5-year survival rate is 68.8%.

What are the symptoms of leukemia in adults?

  • Night sweats.
  • Discomfort in bones or joints.
  • Enlarged spleen, liver or lymph nodes.
  • Pain or feeling of fullness below the ribs.
  • Unexplained weight loss or loss of appetite.
  • Wheezing, coughing or painful breathing.


Can you suddenly develop leukemia?

Acute leukemia symptoms can often appear suddenly

With acute leukemia, symptoms tend to develop very quickly. You may suddenly spike a fever that won't go away, develop an infection for no apparent reason, or start bleeding spontaneously from your nose or gums and not be able to stop it.


What is the best test for leukemia?

The most common test for a leukemia diagnosis is a complete blood count (CBC), which is a diagnostic test that provides information about the cells in a person's blood.

Where is joint pain with leukemia?

Spotting bone and joint pain

Bone pain caused by leukaemia is most commonly felt in the long bones of the arms and legs, or in the ribs and sternum of the rib cage.
