What does this LOINC code represent?

This LOINC code identifies a lab observation, measurement, question, or clinical concept in a standardized format.

Is this enough to understand my test result?

No. The code identifies the test or observation, but the interpretation depends on the actual result, reference range, and clinical context.

What it does not mean

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

Key facts

Enterovirus and Parechovirus A RNA [Identifier] in Specimen by NAA with probe detection

Enterovirus & Parechovirus A RNA

Enterovirus and parechovirus are both in the family picornaviridae. Like enterovirus, parechovirus is thought to be a potential cause of acute gastroenteritis in children, as well as severe central nervous system infection in the neonatal period. It may be underdiagnosed without testing. As a result, it has been recommended that, because of common clinical presentations, real time PCR for both viruses should be performed, especially in the case of atypical neonatal seizures. Annals of Neurology. Verboon-Maciolek 2008. Sept 64(3)266-73 Several labs perform this test, including Quest Diagnostics at Nichols Institute: Enterovirus/Parechovirus RNA, Qualitative Real-Time PCR http://www.nicholsinstitute.com/TestDetail.aspx?TestID=2424
