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 SARS coronavirus 2 Ab.neut. It is commonly used with the system or sample type Ser.

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: pVNT

What it does not mean

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

Key facts

  • SARS-CoV-2 (COVID-19) neutralizing antibody [Presence] in Serum by pVNT
  • SARS coronavirus 2 Ab.neut
  • Qualitative results for SARS Coronavirus 2 (SARS-CoV-2) virus neutralizing antibodies in serum by pVNT (pseudovirus neutralization test). Neutralizing antibody testing is performed to determine whether the antibodies produced after SARS-CoV-2 infection or in response to a vaccination are able to neutralize the virus and prevent infection or re-infection. Different methods can be used to determine the presence of neutralizing antibodies, including VNT (virus neutralization test) and pVNT, which are represented in LOINC as the Method "Neutralization" and "pVNT", respectively. The pVNT method for SARS-CoV-2 neutralizing antibody testing uses recombinant pseudoviruses that incorporate the S protein from SARS-CoV-2, whereas VNT uses SARS-CoV-2 virus from a clinical isolate or recombinant SARS-CoV-2 expressing reporter proteins.
