Reflex Tests Lists test(s) that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial test(s)

Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.

When this test is ordered, a screening panel and a professional interpretation will always be charged. The screening panel will be charged based on number of makers tested (80997 for first marker, 81047 for each additional marker). The interpretation will be set based on markers tested in increments of 9 to 15, or 16 and greater. In addition, reflex testing may occur to fully characterize a disease state or clarify any abnormalities from the screening test. Reflex tests will be performed at an additional charge for each marker tested (80997 if applicable, 81047 if applicable).

 

The tissue panel is initially performed to evaluate for monotypic B-cells by kappa and lambda light chain expression, increased numbers of blasts and plasma cells by CD45 expression along with side scatter gating. The tissue panel also includes antibodies to assess T cells.

 

This panel, together with the provided clinical history and morphologic review, is used to determine what, if any, further testing is needed for disease diagnosis or classification. If additional testing is required, it will be added per algorithm to fully characterize a disease state with a charge per unique antibody tested.

Note: FISH testing may be recommended by the Mayo pathologist in some cases. They will contact the referring physician or pathologist to confirm the addition of these tests.
