MAIN EDUCATIONAL POINTS from M143-1
- Group B streptococcus screening is important to ensure that prospective mothers are given appropriate prophylaxis in the event of a positive result. It is well documented that such treatment has a very positive effect to prevent unnecessary invasive group B streptococcal infection in the infant.
- There are a variety of test modules on the market that are easy to perform, are well controlled and have good sensitivity and specificity.
