What does this LOINC code represent?

This LOINC code identifies a lab observation, measurement, question, or clinical concept in a standardized format.

Is this enough to understand my test result?

No. The code identifies the test or observation, but the interpretation depends on the actual result, reference range, and clinical context.

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 cardiac 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 cardiac transplant
Cell-free DNA.donor/Cell-free DNA.total^post cardiac 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.
