Test Catalog

Test ID: CMAT    
Chromosomal Microarray, Tumor, Fresh or Frozen using Affymetrix Cytoscan HD

Useful For Suggests clinical disorders or settings where the test may be helpful

Genomic characterization of tumor for copy number imbalances and loss of heterozygosity


Assisting in the diagnosis and classification of malignant neoplasms, including hematolymphoid malignancies


Evaluating the prognosis for patients with malignant tumors

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.
