Girls, hi! I wanted to ask you something. They put me in the hospital with swelling, they said to take a urine test tomorrow according to Zimnitzky's method, gave me papers with the time, but I understand all of it, but I don't understand how to collect it. That is, I need to, for example, collect from a certain time until a certain time and then pour it into a separate container and write how much I did there. For example, 300 ml over three hours and write on a piece of paper, aaaah, I'm stupid, especially since I became pregnant, I've become stupid very badly. Explain how to do this correctly.
