90438-3

LOINC code 90438-3 identifies "Mycobacterium preliminary growth [Presence] in Tissue by Organism specific culture". This term represents the preliminary step of the culture process that is used to determine whether or not viable Mycobacteria are 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 Mycobacteria.

This code measures Mycobacterium preliminary growth in Tiss. It belongs to the MICRO class in the LOINC classification.

LOINC (Logical Observation Identifiers Names and Codes) is a universal standard for identifying laboratory and clinical observations. It is maintained by the Regenstrief Institute and used worldwide for health data exchange.
