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.

LOINC Code 75411-9: Ebola Zaire virus RNA NAA+probe Ql (P/Bld)

Name: LOINC Code 75411-9: Ebola Zaire virus RNA NAA+probe Ql (P/Bld)
Creator: HealthAssure Clinical Team
Published: 2026-05-21T08:59:55.158Z

75411-9 is a LOINC code used to identify Ebola Zaire virus RNA NAA+probe Ql (P/Bld) in laboratory and clinical observation data. You may see this code in lab systems, lab reports, EHR exports, interoperability feeds, or other structured clinical data exchanges. LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Ebola Zaire virus RNA. It is commonly used with the system or sample type Plas/Bld.

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 Ebola Zaire virus RNA. It is commonly used with the system or sample type Plas/Bld.

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: Probe.amp.tar

What it does not mean

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

Key facts

Ebola Zaire virus RNA [Presence] in Plasma or Blood by NAA with probe detection

Ebola Zaire virus RNA

The Ebola Zaire PCR assay presumptively detects Ebola Zaire virus, a single-stranded RNA virus identified in the 2014 West Africa outbreak. The assay is used for testing individuals with signs and symptoms of Ebola virus infection, those who are at risk for or may have been exposed to the Ebola Zaire virus, or in accordance with current public health recommendations. The definitive identification of the Ebola Zaire virus requires additional testing and confirmation procedures in consultation with public health. This term was developed for, but is not limited to, use with the Ebola Zaire Target 1 (EZ1) real-time reverse transcription (rRT) polymerase chain reaction (TaqMan®) assay (EZ1 assay), which is run on plasma or whole blood specimens. As of August 2014, the EZ1 assay is approved for use under an FDA Emergency Use Authorization (EUA) [http//www.fda.gov/downloads/MedicalDevices/Safety/EmergencySituations/UCM408334.pdf] by specified laboratories and clinical laboratory personnel who have been trained on instruments authorized by the U.S. Department of Defense.
