What you can expect

By Mayo Clinic Staff

A group B strep test is usually done in a health care provider's office.

During the procedure

You'll lie on your back on an exam table. Your health care provider will use sterile cotton swabs to take samples of cells and secretions from your lower vagina and rectum.

In some practices, you might be given instructions on how to collect the samples yourself.

After the procedure

After the group B strep test, you can return to your usual activities right away.

Test results are typically available within several days.
