LOINC Code 90434-2: Microorganism preliminary growth Aer cx Ql (Plts BPU)

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 Microorganism preliminary growth. It is commonly used with the system or sample type Platelets^BPU.

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: Aerobic culture

What it does not mean

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

Key facts

• Microorganism preliminary growth [Presence] in Platelets from Blood product unit by Aerobe culture
• Microorganism preliminary growth
• This term represents the preliminary step of the culture process that is used to determine whether or not a viable aerobic microorganism is present in the specimen. At the present time (2018), this result would typically be transmitted between laboratory devices and/or stored in the laboratory information system (LIS/LIMS), but it would not be used to order a culture or report culture results to the patient's electronic health record (EHR). Rather, the corresponding LOINC code with Property Prid and Scale Nom is used to order the culture, report this preliminary result, and report the results of any subsequent organism identification tests that are performed. This term was created for, but is not limited in use to, the bioMerieux BacT culture bottles for the recovery and detection of anaerobic and facultative aerobic microorganisms (bacteria and fungi).
