What is this code?

LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Cell-free DNA.donor/Cell-free DNA.total^post lung transplant. It is commonly used with the system or sample type Plas.cfDNA.

When is it used?

  • Used in lab systems, EHRs, and clinical data exchange.
  • May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
  • Status: ACTIVE
  • Order vs observation: Observation

What it does not mean

  • The code identifies the observation or test, not the actual result.

Key facts

  • Cell-free DNA.donor/Cell-free DNA.total in Plasma cell-free DNA --post lung transplant
  • Cell-free DNA.donor/Cell-free DNA.total^post lung transplant
  • The single-nucleotide polymorphisms (SNPs) accurately quantify dd-cfDNA in transplant recipients . The assay quantifies the fraction of dd-cfDNA in both unrelated and related donor-recipients.
