Understanding Lab Tests for Secondary Acute Myeloid Leukemia
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Secondary Acute Myeloid Leukemia (sAML) is a type of blood cancer that develops as a complication of previous blood disorders or cancer treatments. While the primary diagnosis of AML requires comprehensive blood tests including complete blood counts and bone marrow analysis, genetic testing plays a crucial role in understanding the underlying causes and progression of secondary AML.
Recommended Test
JAK2 V617F Mutation Analysis
This genetic test identifies the JAK2 V617F mutation, which is commonly found in patients with Polycythemia Vera, Essential Thrombocythemia, or Primary Myelofibrosis. The presence of this mutation contributes to uncontrolled cell proliferation and can lead to the development of secondary acute myeloid leukemia. Testing for this mutation helps determine the underlying cause and assists in understanding disease progression.

What is Secondary Acute Myeloid Leukemia?
Secondary AML typically develops in patients who previously had myeloproliferative neoplasms such as Polycythemia Vera, Essential Thrombocythemia, or Primary Myelofibrosis. It can also occur after chemotherapy or radiation treatment for other cancers. Blood testing is fundamental for monitoring disease progression and identifying genetic mutations that contribute to leukemia development.
The Role of Genetic Testing
Genetic mutations often drive the transformation from chronic blood disorders to acute leukemia. Identifying these mutations through specialized blood tests helps healthcare providers understand disease mechanisms, assess prognosis, and guide targeted treatment strategies.
Understanding Your Results
The JAK2 V617F mutation test results should always be interpreted by a qualified healthcare provider in the context of your complete medical history and other laboratory findings. A positive result indicates the presence of this specific genetic change, which may explain the progression from a chronic blood disorder to secondary AML.
Important Considerations
The information here is for educational purposes only and is not a substitute for professional medical advice. Secondary AML requires immediate medical attention and comprehensive care from a hematologist-oncologist. Always consult with a healthcare provider for diagnosis and treatment.
