Clinically, the current price of the b-group streptococcus test is about 100, but due to regional differences and hospital differences prices will fluctuate, the price range of tens to hundreds of dollars. Group b streptococcus test is a kind of test for pregnant women and newborns, sampling specimens and then directly culturing the bacterial detection method, which requires the laboratory to provide petri dishes and culture environment, etc., so the price will be slightly more expensive. Group b streptococcus is normally found in the rectal or female genital tract and can cause infection in newborns, especially in newborns delivered through the birth canal. If the pathogenic bacteria inadvertently invade the newborn, it may lead to pneumonia, sepsis, meningitis and other adverse consequences. For women in labor, this pathogen can easily cause decubitus ulcer infections, endometritis and urinary tract infections. Therefore, group b streptococcus screening is very important for both the mother and the newborn, and it is recommended that it be done under the supervision of a doctor to avoid adverse consequences.
