LOINC Code 74749-3: Gram positive blood culture panel Nucleic acid capture and probe detection (Pos bld culture)
74749-3 is a LOINC code used to identify Gram positive blood culture panel Nucleic acid capture and probe detection (Pos bld culture) 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 Gram positive blood culture panel. It is commonly used with the system or sample type Bld.pos growth.
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 Gram positive blood culture panel. It is commonly used with the system or sample type Bld.pos growth.
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: DEPRECATED
- Order vs observation: Order
- Method: Probe.mag capture
What it does not mean
- The code identifies the observation or test, not the actual result.
Key facts
- Deprecated Gram positive blood culture panel by Nucleic acid capture and probe detection in Positive blood culture
- Gram positive blood culture panel
- Identification of 12 Gram-positive bacterial targets and three genetic markers of antibiotic resistance directly from positive blood cultures. Magnetic beads are used to capture nucleic acids followed by oligonucleotide probe detection of sequence of interest. Direct detection (non-PCR) based methods do not involve DNA amplification and therefore avoid amplications of contaminants. This panel was created for, but not limited in use to, Nanosphere's Verigene Gram-Positive Blood Culture test (BC-GP), which uses microarray analysis with probe to identify gram-positive bacteria, including Staphylococcus spp., S. aureus, S. epidermidis, S. lugdudensis, Streptococcus spp., S. pyogenes, S. agalactiae, S. anginosus group, S. pneumoniae, E. faecalis, E. faecium, and Listeria spp. as well as the mecA, vanA, and vanB genes.
