I decided to have the test but just from a birth centre perspective... I chatted about my options with my birth centre midwife and was not at all pressured to have the test. If I had it and came back positive I could still decide how I wanted to manage that (ie. antibiotics in labour were not essential). However if I didn't have the test and ended up being transferred to the main hospital I would be treated as positive and the main hospital pushed antibiotics. Based on that I decided to have it for the chance of being negative so I would be treated that way rather than being treated positive in either case. In the end I was negative and wasn't transferred anyway but I did it for paperwork insurance IYKWIM. I personally hold no value in the test.
