  • Status: ACTIVE
  • Order vs observation: Both

What it does not mean

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

Key facts

Glial nuclear type 1 Ab [Titer] in Cerebral spinal fluid
Glial nuclear type 1 Ab
Glial Nuclear Antibody Antibody (AGNA) Type 1 Cerebrospinal Fluid (CSF) Titer. This antibody is a marker found in paraneoplastic syndrome associated with small cell lung carcinoma (SCLC). It is also closely associated with paraneoplastic Lambert-Easton Myasthenia Syndrome (LEMS). There appears to be a tight association between AGNA and voltage-gated calcium channel antibodies in patients with SCLC. Patients with AGNA have characteristic nuclear staining of the Bergmann glia in the Purkinje cell layer of the cerebellum.

Tavolato, B. Giometto, A. Vincent and Francesc Graus, JNNP m 2007; 78; p. 204-205.
