Chromosome Analysis:
Chromosome analysis may be performed on blood, bone marrow, amniotic fluid, or tissue samples to identify chromosome abnormalities. The specimen is cultured and the harvested cells are stained and viewed under the microscope for numeric and structural abnormalities.
Note:
Chromosome analysis involves the culturing of living cells; thus the turn around time is subject to growth variables. Results are generally available in approximately 7-10 days
Fluorescence in situ Hybridization (FISH):
A molecular cytogenetic technology routinely offered for multiple indications in reproductive, pediatric, and oncology-based medicine. FISH identifies specific chromosomal abnormalities by the presence or absence of fluorescently-colored signals in metaphase chromosomes or interphase nuclei. FISH analysis for rapid diagnosis of aneuploidy is typically provided within 24 to 48 hours from receipt of the specimen. Additional FISH tests include subtelomeric FISH, 24-color M-FISH tests, and cross-species color banding (RxFISH).
Prenatal Diagnosis:
Chromosome analysis and Fluorescence in situ Hybridization (FISH)are performed on amniotic fluid, peripheral and umbilical bloods, tissue and chorionic villus sampling specimens.
Preimplantation Genetic Diagnosis (PGD):
Fluorescence in situ Hybridization (FISH) is performed on blastomeres.
Cancer Genetics:
Chromosome analysis and Fluorescence in situ Hybridization (FISH) are performed on bone marrow, leukemic blood, lymph node, and tumor specimens.
