Doctors may test your child’s blood, bone marrow or other body tissue to look for changes in the chromosomes of cancer cells. These tests help tell the specific type of cancer and guide doctors in choosing the best treatment for your child. This is called cytogenic testing.
Through our precision medicine program, we develop new clinical lab tests such as gene sequencing. We will give you all the information we can about your child’s tumor. We will also explain how the information may be used now or in the future.
Sometimes a specialist sees chromosomal changes by looking at the cells under a microscope. Seattle Children’s Genetics Lab also does more specialized tests, including fluorescence in situ hybridization (FISH). This test helps in diagnosing some cancers and deciding if certain targeted drugs might help. A board-certified cytogeneticist reviews and interprets the results.
