LOINC Code 80620-8: ZIKV neut ab Neut test (S) [Titer]

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 Zika virus 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: Neut

What it does not mean

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

Key facts

• Zika virus neutralizing antibody [Titer] in Serum by Neutralization test
• Zika virus Ab.Neut
• Quantitative result for Zika virus neutralizing antibodies in serum. Serological cross-reactivity is strong between Zika and other flaviviruses, especially Dengue virus. Therefore, positive EIA or IF assays for Zika virus IgM antibodies are presumptive only and should be confirmed by a neutralization assay, such as the plaque-reduction neutralization test (PRNT), which can discriminate between Zika virus and cross-reacting antibodies in primary flavivirus infections. Recent Zika virus infection is confirmed by stable high neutralizing antibody titers, seroconversion, or a 4x or greater increases in neutralizing antibody titer in a patient's appropriately timed acute and convalescent phase sera.
