Didn’t expect to back here..

59 is elevated but not massively. What is more revealing is what it does over time, bearing in mind you need to leave it a month between tests. So what might happen is another test in a few weeks to see what's happening. No doctor would act on this test alone, they rely on bloods, symptoms and scans taken together. So I suspect you may have to sit tight for a bit...unless you have symptoms which might bring forward a referral for a scan.

Terrifying as this must feel, you probably won't find any peace till you know what's going on. I hope you don't have to wait too long
