DIAGNOSTIC SERVICES

Cytogenetics / Karyotyping

Karyotyping, also called whole genome chromosomal analysis, can differentiate primary and secondary changes; can address why, how, when and where chromosome abnormalities arise. Thus provide insights into diagnosis, prognosis, and prediction of disease in many acute and chronic leukemias and lymphomas. Traditional G-banding for at least 20 metaphase analyses with specific cell culturing and analyzed by two independent ASCP-certified Cytogenetic Technologists ensures optimal results.

FISH

Fluorescence in situ hybridization (FISH) is a molecular cytogenetic method, and works as an adjunct to karyotype analysis for the detection of cytogenetic abnormalities. FISH can help provide clarification of G-banded abnormalities or identify cryptic abnormalities not visible by karyotype analysis. The main advantages of FISH include: high sensitivity and specificity, rapid turnaround time, capacity to analyze large numbers of cells, and ability to obtain adequate data from samples with a low mitotic index or terminally differentiated cells. Also, dividing cells are not required for FISH analysis using both fresh tissue and paraffin-embedded tissue.

In general, two hundred interphase cells are analyzed per probe by two independent ASCP certified Cytogenetic Technologist (100 cells/reader).

FISH is most useful when the analysis is targeted toward specific translocation, rearrangement and gain or loss that are known to be associated with a particular disease. We offer the following Disease-focused FISH panels with the best-in-industry turnaround time (1-2 days)
