LOINC Code 75635-3: Rheumatoid arthritis disease activity panel VectraDA

75635-3 is a LOINC code used to identify Rheumatoid arthritis disease activity panel VectraDA 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 Rheumatoid arthritis disease activity panel. 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 Rheumatoid arthritis disease activity panel. 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: Order
  • Panel type: Panel
  • Method: VectraDA

What it does not mean

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

Key facts

  • Rheumatoid arthritis disease activity panel - Serum or Plasma by VectraDA
  • Rheumatoid arthritis disease activity panel
  • Rheumatoid arthritis (RA) disease activity panel includes the assessment of multiple biomarkers in a patient's serum to determine overall disease activity in adults diagnosed with RA. Currently, 12 biomarkers are evaluated, including epidermal growth factor (EGF), vascular endothelial growth factor A (VEGF-A), leptin, interleukin 6 (IL-6), serum amyloid A (SAA), CRP, vascular cell adhesion molecule 1 (VCAM-1), matrix metalloproteinase 1 (MMP-1), matrix metalloproteinase 3 (MMP-3), tumor necrosis factor receptor superfamily member 1A (TNF-RI), human cartilage glycoprotein 39 (YKL-40), and resistin. The assessment includes the overall RA disease activity score, score level (high, medium, low), and score confidence interval range (lower and upper limits). This panel term was created for Crescendo BioScience's VectraDA blood test for rheumatoid arthritis disease activity.
