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: CBA IFA

What it does not mean

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

Key facts

  • THSD7A IgG Ab [Titer] in Serum or Plasma by Cell binding immunofluorescent assay
  • Thrombospondin type I domain-containing 7A Ab.IgG
  • Quantitative detection of IgG antibodies against thrombospondin type-1 domain-containing protein 7A (THSD7A) in serum or plasma by immunofluorescent methods to assist in the diagnosis of primary membranous nephropathy (pMN, also known as primary membranous flomerulonephritis, pMGN). This term was created for, but not limited in use to, the submitter's test kit, EUROIMMUN Anti-THSD7A IIFT, which provides qualitative or semiquantitative determination of IgG antibodies against THSD7A.
