Chromosome Analysis, Solid Tumor
Use
Detection of chromosomal abnormalities with subgroup-specific diagnostic and prognostic significance (eg, t(11;22) in Ewing sarcoma)
Special Instructions
Not provided.
Limitations
The test has not been cleared or approved by the FDA. Chromosomal analysis may not detect all chromosomal abnormalities and does not rule out the presence of neoplasia. The effectiveness of the analysis can vary based on tumor type due to potential contamination with normal stroma or lack of viable tumor cells.
