• Acute Lymphoblastic Leukemia (ALL) is the most common childhood cancer, but also occurs in adults. 

• ALL develops from the overproduction of immature lymphocytes, leading to too many immature leukemic lymphoblasts in the blood and an imbalance in the normal percentages of cells.

• FISH testing can help in identifying the genetic changes underlying this disease.

​

Sample Requirements:

  • 5 mL in a EDTA (purple top) is acceptable for FISH and molecular testing only

  • Minimum: 1 mL
