Strep B Carrot Broth One-Step

Strep B Carrot Broth™ One-Step, for the detection of hemolytic Group B Strep in pregnant women, no reaction tile required, 13x100mm tube, 4ml fill, 20 tubes per box.


Our new tile-less system allows for fast results for the cultivation and identification of beta-hemolytic strains of Group B Streptococcus.


Strep B Carrot Broth™ One-Step is a selective and differential medium which is intended for the detection of Group B Streptococcus (GBS) from anovaginal specimens collected from pregnant women. The medium is used as an aid in the qualitative determination of GBS colonization in pregnant women. The color change reaction from white to orange is representative of a positive result for presence of hemolytic GBS.

Our one-step test is an improvement over conventional methods by increasing sensitivity, decreasing turn-around time, and lowering overall cost. All components are now included in the color change test, so the use of additional tiles is no longer necessary. Positives require no follow up testing!
