LOINC Code 80912-9: Gadolinium [Mass/Vol]
80912-9 is a LOINC code used to identify Gadolinium [Mass/Vol] 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 Gadolinium. It is commonly used with the system or sample type Ser/Plas.
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 Gadolinium. It is commonly used with the system or sample type Ser/Plas.
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
What it does not mean
- The code identifies the observation or test, not the actual result.
Key facts
- Gadolinium [Mass/volume] in Serum or Plasma
- Gadolinium
- Due to its paramagnetic properties, chelated gadolinium is commonly employed as contrast media for magnetic resonance imaging (MRI) and computer tomography (CT) scanning. Gadolinium is eliminated primarily by the renal filtration. In healthy subjects with normal renal function, the plasma half-life of gadolinium is approximately 90 minutes. Patients with reduced renal function exhibit increased gadolinium excretion half-life and may be affected by nephrogenic systemic fibrosis (NSF). In this syndrome, prolonged retention of gadolinium is thought to allow the gadolinium cation to dissociate from its synthetic organic chelator and deposit predominantly in the skin, although other organs may be affected as well. These patients are often severely debilitated by progressive skin thickening and tightening. Fibrosis of skeletal muscle, lungs, liver, testes, and myocardium have also been observed, often with fatal results. Three hemodialysis treatments are required to substantially remove gadolinium from patients with impaired renal function; peritoneal dialysis is not effective.
