Chromosomal Microarray, Tumor, Fresh or Frozen using Affymetrix Cytoscan HD

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

DNA is extracted from the specimen prior to hybridization to the microarray. An unstimulated cell culture will be set up on all specimens with adequate volume and held pending additional testing. If additional testing is requested, such as karyotype analysis or FISH, it will be performed at an additional charge.

Specimen Type Describes the specimen type validated for testing
