In plain language

What this test helps you understand

This test helps identify individuals carrying Group B Streptococcus, allowing for timely intervention, especially during pregnancy, to prevent serious infections in newborns.
The Streptococcus Group B Antigen Detection Test is used to identify the presence of Group B Streptococcus (GBS) bacteria. GBS is a common bacterium that can cause serious infections in newborns if passed from the mother during childbirth. This test is particularly important for pregnant women. Early detection allows healthcare providers to take steps to protect the baby's health. The test uses a rapid and reliable method called Latex Agglutination to detect GBS antigens. We offer this test at our branches in major Kenyan cities and provide a home sample collection service for convenience.
