Strep B Antigen Rapid Tests (25 Test Kits)
STREPTOCOCCI are human pathogenic, gram-positive, chain-forming bacteria. Approximately 10-30% of all pregnant women are colonized with Group B streptococci (Strept. agalactiae) in the intestine or vagina, without the mother suffering from any illness (asymptomatic carrier). This colonization often leads to transmission to the newborn during the birth process, at the onset of labor, or with premature rupture of membranes.
Group B streptococci are highly pathogenic for newborns. In early-onset infection, transmission occurs during birth and becomes evident in the first days of life; in general infection, illness is observed in the first weeks of life. The incidence of Group B streptococcal infections in newborns is 1-5%, with a mortality rate of up to 80%. Testing is recommended for all pregnant women in the 3rd trimester.
RISK FACTORS for neonatal infection:
- High bacterial density in maternal colonization
- Maternal urinary tract infections with or without vaginal involvement by Group B streptococci during pregnancy
- Gestational age < 37 weeks
- Prolonged rupture of membranes > 18 hours
- Intrauterine infections
- Young maternal age
- Previous birth of a child with a Group B streptococcal infection
PREVENTION
To reduce the risk of neonatal illness, the professional societies of gynecologists and infectious disease specialists have developed recommendations. Components of effective prevention include:
- Screening of pregnant women between the 35th and 37th week of gestation for the presence of Group B streptococci in the vagina and rectum (swab).
- Prophylactic administration of antibiotics during labor for positively tested mothers throughout childbirth.
The combination of both measures can reduce the incidence to < 1 case per 1000 live births. This Strep B antigen test is a fast and reliable chromatographic immunoassay for the qualitative detection of Group B Streptococcus antigens from swabs.
