The AML/ETO Quantitative RT-PCR Test is a molecular diagnostic procedure performed on a blood or bone marrow sample. This test is primarily used to diagnose and monitor the progress of Acute Myeloid Leukemia (AML), a type of blood cancer. AML is characterized by the rapid growth of abnormal cells that build up in the bone marrow and blood, interfering with normal blood cell production.
The AML/ETO (also known as RUNX1/ETO or t(8;21)) gene fusion is one of the most common genetic abnormalities associated with AML. It is created by the translocation (exchange of genetic material) between chromosomes 8 and 21. This test uses the reverse transcription-polymerase chain reaction (RT- PCR) technique to detect and quantify this gene fusion in a patient's blood or bone marrow.
The RT-PCR for AML/ETO Quantitative test is crucial for the diagnosis of AML. It can also be used to monitor treatment response in patients with AML and help predict their prognosis.
No, fasting is not necessary before this test.
A blood sample or bone marrow sample is required for this test.
This test is usually ordered if you have signs or symptoms suggestive of AML, or if you've been diagnosed with AML and your doctor wants to monitor your response to treatment.
This test detects and quantifies the AML/ETO gene fusion in your blood or bone marrow. The presence of this fusion gene indicates AML, and its quantity can help assess the severity of the disease and the effectiveness of treatment.
Your healthcare provider will determine the frequency of this test based on your health condition and response to treatment.
The absence of the AML/ETO gene fusion is considered normal. However, if you have been diagnosed with AML, the goal is to reduce the levels of this gene fusion as much as possible with treatment.
No special precautions are necessary before this test. However, inform your doctor about any medications you're taking, as some may interfere with the test results.
Certain medications and the presence of other genetic abnormalities may affect the test results.
If your test results are abnormal, you should consult with a hematologist or an oncologist.
The presence and increased levels of the AML/ETO gene fusion are primarily associated with Acute Myeloid Leukemia. Its levels can decrease with effective treatment.
A healthcare professional will clean your skin, insert a needle into a vein to draw blood, or perform a bone marrow aspiration or biopsy to collect a marrow sample. The needle is then removed, and a bandage is applied to the puncture site.
Risks associated with blood sample collection are minimal and can include slight pain, bruising at the puncture site, or lightheadedness.
No special preparation is required for this test.
Yes, the RT-PCR for AML/ETO Quantitative test can help predict the progression of AML. High levels of the AML/ETO fusion gene are typically associated with more aggressive disease.
In conclusion, the RT-PCR for AML/ETO Quantitative test is a valuable tool in diagnosing and monitoring AML. If you have been diagnosed with AML, understanding your test results can be crucial in managing your disease. Always discuss your results with your healthcare provider to understand what they mean for your specific situation.
