everyone has to 抽两管血?? I 抽了one bottle only. That nurse originally planned to 抽两管, but she at the end 抽了one bottle only. I asked her whether she needed to 抽 one more bottle. She said that's fine, one is enough.
so i suppose she 查肝and HIV by using only ONE bottle. The left bottle that u mentioned is only for spare use. Right??
