LOINC display name : Bacteria identified LA Nom (CSF);
LOINC long common name : Bacteria identified in Cerebral spinal fluid by Latex agglutination;
LOINC short name : Bacteria CSF LA;
LOINC 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.;
