Term Description

A latex agglutination test for antigens in CSF in cases of suspected bacterial meningitis. The most common bacteria antigens tested for are Haemophilus influenzae; Streptococcus pneumoniae; Neisseria meningitidis A; Neisseria meningitidis B; Neisseria meningitidis C. Because the primary purpose is the identification of N. meningitidis, S. pneumoniae, and H. influenzae from clinical specimens collected from suspected cases of bacterial meningitis, the methods do not allow identification of other isolates that may be of clinical importance but are less likely encountered. In the US rarely used due to very poor positive predictive value. Occasionally used to diagnose bacterial meningitis in a patient who is pre-treated with antibiotics. Given current vaccines available in the US (example: pneumococcal, haemophilus influenzae type b (Hib) vaccine), bacterial meningitis is a rare event in the US.

Part Descriptions

LP14082-9   Bacteria
One of the three domains of life (the others being Eukarya and Archaea), also called Eubacteria. They are unicellular prokaryotic microorganisms which generally possess rigid cell walls and multiply by cell division. They exhibit three principal forms: round or coccal, rodlike or bacillary, and spiral or spirochetal. Bacteria can be classified by their response to oxygen (aerobic, anaerobic, or facultatively anaerobic) and by how they obtain their energy (chemotrophic, i.e. via a chemical reaction or phototrophic, via a light reaction). In addition, chemotrophs obtain their energy from chemicals, lithotrophic from inorganic compounds and organotrophic from organic compounds. Bacteria are also classified by the source carbon that they utilize: heterotrophic, from organic sources or autotrophic, from carbon dioxide. They can also be classified by whether or not they stain (based on the structure of their cell walls) with crystal violet dye: gram-negative or gram-positive.

LP37205-9   Bacteria identified
Bacteria identification in various specimens (urine, blood, stool, etc.) by culture or other method is performed to determine the cause of an infection or illness. For most routine cultures, the lab is looking for bacteria. Such cultures may also grow out fungi, and if so they too would also be reported under the same test name. But, the cultures would not be optimized for growing out fungi hence the bacteria-focused name. Therefore, a routine urine culture, for example, would be mapped to this code:
