Diagnostic Cytogenetic, Inc.’s board certified

cytogeneticists, medical geneticists, and pathologists are always available for consultation or discussion of solid tumor indications.

  • Chromosome Analysis

    Indication for Testing

    • Adjunct to histological diagnosis of solid tumor.
    • Indicate prognosis of disease process.

    Abnormalities Detected

    Chromosome Analysis Detects:

    • Aneuploidy (monosomy, trisomy)
    • Deletions and duplications (>5Mb)
    • Translocations
    • Inversions

    Chromosome Analysis Does Not Detect:

    • Deletions or duplications that are too small to be seen by microscope (<5Mb)


    G-banded chromosomes from 20 metaphase cells are completely analyzed and at least 3 karyograms are prepared. Additional chromosome analysis and special banding techniques are employed as needed.

  • FISH Testing

    Our full FISH menu is available for testing on fresh solid tumor tissue.  For paraffin embedded tissue, consult our FFPE menu.  Please contact us to discuss indication-specific FISH testing strategies.
