Flow Cytometry, Additional Cell Marker

Maryland rates for HCPCS 88185

This covers testing an additional marker in a flow cytometry study, a laboratory technique that identifies specific proteins on the surface of individual cells by passing them one at a time through a laser-based detector. Each marker gives information about what type of cell is present and what state it is in, and looking at several markers together helps build a full picture. It applies for each marker beyond the first analyzed from the same sample.
