The Stanford Cytogenetics Service offers a comprehensive menu of testing for the diagnosis of chromosomal abnormalities present at birth and those that are acquired as various diseases progress. We offer chromosome, fluorescence in situ hybridization (FISH) and microarray analysis for many indications and sample types including peripheral blood, bone marrow, amniotic fluid, chorionic villus sampling (CVS), products of conception, skin biopsies, and solid tumors.
Chromosome analysis involves the testing of blood, bone marrow, prenatal (amniotic fluid and chrionic villi) and other tissues for rearrangement, loss, gain and breakage for rearrangement, loss, gain and breakage of the metaphase chromosomes. FISH (fluorescence in situ hybridization) and aCGH/CMA (array comparative genomic hybridization/chromosomal microarray) involves the indirect analysis of chromosomes, interphase nuclei or extracted DNA using molecular probes and molecular cytogenetic methodologies.
Our board-certified laboratory directors work closely with physicians, genetic counselors and hospital staff to identify the proper testing for the specimen available.
