Group B Strep┃Testing and Treatment Explained

hi i'm dr. wendy wagner and i am doing

some additional ob/gyn topics i haven't

done any videos in a while so today i'm

going to be talking about Group B Strep

it is a test that we do at 35 to 37

weeks of pregnancy and some people don't

have that full understanding of what it

is or what the treatment is so I'm going

to try to straighten that out today so

Group B Strep

is a bacteria that some people's GI

tract er colonized with it can be

intermittently colonized and that's why

we do the testing for Group B Strep at

the end of pregnancy the reason that we

do the test is that women that are

colonized at the end of pregnancy needs

to be treated and labor in order for

babies not to be affected slash infected

we have the Group B Strep

years ago it was found that women that

were colonized with grease trap some of

their babies would be infected after a

vaginal delivery few babies were

infected but the infection can be so

severe that babies can get very sick and

even can die from this infection so for

many years we've been testing women at

35 to 37 weeks of pregnancy between 20

and 30 percent of women are colonized

with Group B Strep at the time of

delivery and the hope is that we've

tested those women and all of them are

treated at the time of delivery so that

the babies will get infected so a xxx

about 36 weeks of pregnancy women get a

test for through B Strep the very simple

test what it is is a swab what we call a

vaginal rectal swab so it's just a fence

well the lower portion of vagina and the

rectum is swab for Group B Strep

that is then placed in this media and

sent to the lab for either positive or

negative result no speculum is used for

the exam this exam is done before any

internal exam or anything like that is

done when the result comes back it's

either positive or negative the only

difference in testing is if somebody is

if somebody has an allergy

to penicillin or ampicillin which is

what we use to treat group ejaculation

and labor and sometimes we do testing to

see if other medications can be used so

if you're a positive for Group B Strep

then you can enter products the labor

the only thing that's going to be

different is through the IV you're going

to give antibiotics every four hours

from labor or rupture of membranes to

delivery the only thing that may be

different is that you provider may tell

you if you have our positive for Group B

Strep to come in a little bit earlier in

labor if you broke your water because

there is an advantage to getting four

hours of the antibiotic or two doses of

antibiotics before delivery if you're

having a scheduled c-section haven't

broken your water you don't need any

treatment for Group B Strep

the other time that we treat for Group B

Strep is quote unquote preterm so

anybody who delivers before 36 completed

weeks regardless of the Group B Strep

status is treated for Group B Strep

if the status is unknown we treat until

the status is known so in other words if

somebody either is in preterm labor or

their waters broken prematurely then we

treat them until the result comes back

if they're negative then we stop that

treatment all right so it's three quick

points first one being that even if you

have a scheduled c-section or c-section

that you have scheduled and you are you

know max likely to have a vaginal

delivery we still do the group B strep

culture the reason is that if your water

breaks before delivery and you need to

get treatment or their it needs to be

known by a pediatrician whether what

your Group B Strep status is two other

important points where you don't have to

have the group B strep swab done at

about proximately 36 weeks and that is

the times when you're automatically

treated for Group B Strep these times

are if you had groupies strep in your

urine during the pregnancy so the first

visit for your pregnancy Group B Strep

is shown whether or not you were treated

for this you're automatically treated at

the time of delivery so you don't need

this vodka the other circumstances if

you had a baby that was affected by

Group B Strep

to have a poopy strep infection in the

past you are automatically treated for

Group B Strep

during labor and delivery because of the

increased risk of this infection so you

will get the testing done hopefully

you'll understand about the result and

about the treatment and the reason that

we do it
