    NNLX BNF Rapid Detection verse Culture (Gold Standard)

    In parents' post this fact was pointed out:

    "First, he pointed out that the experiment was designed to determine sensitivity to Clindamycin rather than GBS detection sensitivity, per se."

    So, interpret what I said here with caution as I do not know exactly how this relates to AST testing--- at first I was interpreting it as overall GBS sensitivity and specificity, but am not sure if this is the case.

    Could really use the help of a medical professional in the interpretation. Perhaps parents could get the Swiss friend onto this board.

      • Hi All ;
        I think this link will be instructive.
        DETECTION OF GROUP B STREPTOCOCCUS IN BRAZILIAN PREGNANT WOMEN AND ANTIMICROBIAL
        SUSCEPTIBILITY PATTERNS.
        It is a paper comparing PCR to petri dishes, around page six (6), it compares the petri dish and PRC results. The PRC identified more then the petri dish, as does the Nanologix petri dish.

        Below is from the paper.

        Table 4. Group B Streptococcus agalactiae prevalence in 221 pregnant women admitted in labor considering two methodological
        approaches.

        Anorectal 10 (47.6%) 16 (22.2%)
        Both sites in the same patient 4 (19%) 24 (33.4%)
        Total of GBS colonized patients 21 (100%) 72 (100%)

        Here is the complete paper.

        Only my opinion.
