Protien in urine

Kedra • I have two sons, a 9 year old and 6 year old. Also had a premature birth November 27th 2016 at 23 weeks, unfortunately he wasn't considered viable and we lost him. Had our rainbow baby girl in October 2019.👦🧒👼👶

Can someone please explain to me what a normal amount of protein in urine is? I had to do a 24 hour urine test and I just got my results back and it says value is <142 in 24 hours
