Additional information related to the test.
Chromosome breakage study performed by culturing cells in both Mitomycin-C (MMC) and Diepoxybutane (DEB). These studies involve culturing of living cells; therefore, turnaround times given represent average times, which are subject to multiple variables. A routine Giemsa Banded Chromosome Analysis is included with breakage analysis.
A processing fee will be charged if this procedure is canceled at the client's request after the test has been set up, or if the specimen integrity is inadequate to allow culture growth.
