Summary
This is a Proprietary Laboratory Analyses (PLA) code, meaning that the code applies to only one unique lab test made by a specific manufacturer or performed by a specific lab. Report 0540U only for AlloSure® from CareDx® Laboratory. This test for transplant monitoring measures donor–derived cell–free DNA (dd–cfDNA) levels in plasma to help determine the probability of organ rejection. It uses next–generation sequencing (NGS) to analyze DNA from the recipient's bloodstream and calculates the percentage of DNA originating from the transplanted organ.
