Culture, Urine, Prenatal, with GBS Susceptibilities Test
This test is a quantitative urine culture performed in a prenatal context, with susceptibility testing added if Group B Streptococcus (GBS) is found. Quest describes it as helping to differentiate significant bacterial counts from contamination introduced during sample collection.
About this test
The test measures bacteria present in a urine sample through quantitative culture. Because urine passes through areas of the body that carry normal flora during collection, Quest describes the quantitative approach as a way to help tell apart bacterial counts that are clinically significant from contamination picked up during voiding.
The name identifies this as the prenatal version of a urine culture, which includes susceptibility testing for Group B Streptococcus (GBS) as part of the result, in addition to the general culture. Susceptibility testing is performed for each organism isolated when the culture is positive, and reports which treatments the organism responds to.

What this test looks at
The test reports a urine culture result with Group B Strep susceptibilities from a 4 mL random, clean catch, midstream urine sample, using culture methodology. If the culture is positive, the lab performs susceptibility testing separately for each organism it identifies in the culture.

Frequently asked questions
What does this test measure?
It measures bacteria present in a urine sample using quantitative culture, and includes susceptibility testing for Group B Streptococcus (GBS) if the culture is positive.
How is the sample collected?
The test uses a 4 mL random, clean catch, midstream urine sample.
Do I need to prepare for this test?
No preparation instructions are listed for this test, though people follow any instructions their ordering clinician provides.
Why is a quantitative culture used instead of just checking for bacteria?
Quest describes the quantitative approach as a way to help differentiate significant bacterial counts from contamination that can be introduced as urine passes through areas with normal flora during collection.
