@hello1234 My apologies for not keeping in touch soon. I just got a part-time remote job, and it has been hectic.
They identified the rejection was elevated through the Prospera blood test. It is more comprehensive and detects early rejection which later shows up on the usual creatinine test. I was told it is fairly new and existed a couple of years ago. I did another test today. The creatinine is better from 1.12 last week to 1.04. I also did another Prospera test as recommended by my UCLA nephrologist. If it goes further up, then they will schedule biopsy. In looking at the five test results, they were all in upward pattern. Most likely, the test today is up too. Last week, they also took antigens test. It came out good as no antibodies were detected against the antigens. There's always good news and bad news. Like everyone else, I entrust our doctors recommend the best course of action to keep us on the right track.
