One of the most relevant tests that can be performed in the ninth month of pregnancy is the strep test. Specifically, this test that detects infections by group B streptococcus bacteria is performed between the 35th and 37th week of gestation.
The following are the main risk factors associated with streptococcal infection:
- History of previous group B strep infections during the same pregnancy.
- Urinary tract infections with the bacteria during pregnancy.
- Having had a baby with a group B strep infection in previous pregnancies.
