Test ID: CHFXH    
Chromosome Analysis, Hematologic Disorders, Fixed Cells

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

This test only includes a charge for professional interpretation of results and does not include charges for analysis.

 

Analysis charges will be incurred for total work performed, and generally include 2 banded karyograms and the analysis of 20 or more metaphase cells for this test. If no metaphase cells are available for analysis, no analysis charges will be incurred. If additional analysis work is required, additional charges may be incurred. See the Method Description for specific details.
