Strep B Carrot Broth™ Kit* for the detection of hemolytic Group B Strep in pregnant women, 20 tests per kit, includes tiles, by Hardy Diagnostics

Strep B Carrot Broth™ is a one-step method for cultivation and identification of hemolytic strains of Group B Streptococcus.

This test is an improvement over conventional methods by:

  • Increasing sensitivity

  • Decreasing turn around time

  • Lowering overall cost.

  • Positive results for beta hemolytic strains can be observed as early as 6 hours after inoculation.

  • If negative on Carrot Broth, non-hemolytic strains can be tested on Hardy's GBS Detect plate (Cat. no. A300, see link below).

  • See Z140T if extra tiles are needed.

  • *US Patent No. 8,313,938 B1 and US Patent No. 8,518,688 B1

  • Excerpt from the CDC's Guidelines:

    Procedures for processing clinical specimens for culture of group B Streptococcus (GBS)
    "Remove swab(s) from transport medium. Inoculate swab(s) into a recommended selective broth medium, such as Todd-Hewitt broth supplemented with either gentamicin (8 µg/ml) and nalidixic acid (15 µg/ml) [TransVag broth], or with colistin (10 µg/ml) and nalidixic acid (15 µg/ml) [Lim broth]. TransVag broth may be supplemented with 5% defibrinated sheep blood to increase the recovery of GBS. As an alternative, swabs may be inoculated into selective enrichment broth that incorporates chromogenic pigments for the detection of beta-hemolytic GBS using color detection. Examples of appropriate commercially available options include StrepB carrot broth or Granada Biphasic broth."
