How long do leukemia Test results take?

Cytogenetic testing usually takes about 2 to 3 weeks because the leukemia cells must grow in lab dishes for a couple of weeks before their chromosomes are ready to be looked at.

How do you confirm leukemia diagnosis?

A blood test showing an abnormal white cell count may suggest the diagnosis. To confirm the diagnosis and identify the specific type of leukemia, a needle biopsy and aspiration of bone marrow from a pelvic bone will need to be done to test for leukemic cells, DNA markers, and chromosome changes in the bone marrow.

Can leukemia be misdiagnosed?

Leukemia Misdiagnosis Physicians often fail to diagnose chronic leukemia, as it often shows no symptoms until the disease has begun to progress. Many of the symptoms of leukemia may also be symptoms of other illnesses, which results in a high number of misdiagnoses.

Can leukemia be diagnosed without a bone marrow biopsy?

A bone marrow biopsy is usually not needed to diagnose CLL, but it may be done before beginning treatment. For some patients, a bone marrow aspiration and biopsy may help determine prognosis, which is the chance of recovery.

What do blood tests show if you have 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.

What labs check for leukemia?

Complete blood count (CBC): This blood test gives details about red blood cells, white blood cells and platelets. If you have leukemia you will have lower than normal counts of red blood cells and platelets, and higher than normal counts of white blood cells. Some leukemia cells may be found.

Why would a doctor order a blood test for leukemia?

If there is reason to think low levels of blood cells might be causing your symptoms (anemia, infections, bleeding or bruising, etc.), the doctor will most likely order blood tests to check your blood cell counts. You might also be referred to a hematologist, a doctor who specializes in diseases of the blood (including leukemia).

Can leukemia be diagnosed without a bone marrow sample?

Even though these findings may suggest leukemia, the disease usually is not diagnosed without looking at a sample of bone marrow cells. Blood chemistry tests: Blood chemistry tests measure the amounts of certain chemicals in the blood, but they are not used to diagnose leukemia.

What can a physical exam tell me about leukemia?

A physical exam will be done to look for possible signs of leukemia and other health problems. During the exam, your doctor will pay close attention to your lymph nodes, abdomen (belly), and other areas that might be affected. Your doctor may also order tests to check your blood cell counts.

Can DNA testing for leukemia tell you your risk factor?

DNA testing for leukemia isn’t typically completed to determine one’s risk factor for most leukemia types because the cell mutation isn’t often hereditary, but there is a DNA test available that could determine your risk of developing chronic lymphocytic leukemia (CLL).
