WHO CAN TAKE THE TEST

Group B Strep infection can cause, premature rupture of membranes (waters breaking) and premature labour and major infection for the mother, such as sepsis.

Strep B Sure is recommended for all pregnant women, as carrying Group B Strep is the most important risk factor for newborn disease due to transmission during the birth.

 

STREP B SURE

Recommended after 35 weeks of pregnancy

Group B Strep is a common bacteria with no symptoms being shown when carrying, with testing the only way to determine if someone is carrying the bacteria. Group B Strep can cause infection in new-born babies which is why testing before birth is important.


Many women give birth while carrying Group B Strep, and in majority of cases babies are born safely without developing infection.

An average of 66 babies a month are diagnosed with Group B Strep infection with most making a full recovery, however each month on average 6 babies survive with long term disabilities and 4 babies die due to infection.

A Group B Strep swab test is simple, safe and effective.

The ECM test (Enriched Culture Medium): 

This test was designed specifically to detect Group B Strep carriage, and is described by Public Health England’s UK SMI B58 [1]. It is available from a small number of NHS trusts as well as from several private laboratories. The method takes samples from two sites, one from the low vagina and one from the rectum (using two separate swabs.) The cells from the swabs are first incubated in an enriched culture medium specifically designed to encourage the growth of group B Strep and thus enhancing its detection. The samples are then plated in the same way as conventional tests.

Research [2] has shown that, when the ECM test is properly performed within 5 weeks of delivery:

i. A positive result was 87% predictive of carrying group B Strep at delivery (13% of women lost carriage between performing the test and giving birth)

ii. A negative result was 96% predictive of not carrying group B Strep at delivery (4% of women acquired carriage between the test and giving birth) [2].
