LOINC Code 79102-0: Heart transplant acute cellular rejection risk Calculated by AlloMap (Bld MC) [Score]

79102-0 is a LOINC code used to identify Heart transplant acute cellular rejection risk Calculated by AlloMap (Bld MC) [Score] in laboratory and clinical observation data. You may see this code in lab systems, lab reports, EHR exports, interoperability feeds, or other structured clinical data exchanges. LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Heart transplant acute cellular rejection risk. It is commonly used with the system or sample type Bld MC.

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 Heart transplant acute cellular rejection risk. It is commonly used with the system or sample type Bld MC.

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: Both
  • Method: Calculated.AlloMap

What it does not mean

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

Key facts

Heart transplant acute cellular rejection risk [Score] in Mononuclear cells Calculated by AlloMap
Heart transplant acute cellular rejection risk
This term is used to report the risk score for moderate to severe (grade 3A or higher) acute cellular transplant rejection in heart transplant recipients with stable allograft function. The test assesses the expression of 11 genes (ITGAM, FLT3, IL1R2, G6B, PF4, WDR40A, MIR, ARHU, PDCD1, ITGA4 AND SEMA7A) using PCR with RNA isolated from peripheral blood mononuclear cells, and the gene expression data is then used to calculate a score that ranges from 0-40, with a lower score indicating a lower risk for rejection. In the Cardiac Allograft Rejection Gene Expression Observational (CARGO) study, patients who were at least 12 months post-transplant and who had a score less than 30 were very unlikely to have grade 3A acute cellular rejection at the time of testing (negative predictive value 99.6%). [PMID16433769] This term was created for XDx Reference Laboratory's AlloMap test, which is indicated for heart transplant patients who are at least 15 years of age and 55 or more days post-transplant.
