Test ID: CMAPT    
Chromosomal Microarray, Tumor, Formalin-Fixed Paraffin-Embedded

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


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.

This test does not include a pathology consult. If a pathology consultation is requested, PATHC / Pathology Consultation should be ordered and the appropriate fluorescence in situ hybridization (FISH) test will be ordered and performed at an additional charge.


Hematoxylin and eosin stain review of the paraffin-embedded sample is performed to identify the area of invasive tumor prior to DNA extraction and microarray analysis. If additional FISH testing is requested, it will be performed at an additional charge.


If a fresh tissue specimen is submitted, this test will be cancelled and CMAT / Chromosomal Microarray, Tumor will be performed.
