Having my calcium, vit d, and pth checked every 6 weeks, pth was 67, 45, now 26, calcium 10.8, 10.2,10.3, now 11,pth dropping mean anything?

Confusing picture: Hi. That's a confusing set of labs. There are 3 PTH's and 4 calciums (Ca), so I'm not sure exactly which ones go together, but assuming (which can be dangerous), it looks like you had a high Ca (10.8) with a high or at least not suppressed PTH (67, which would be slightly hi in most labs) on one occasion and a hi Ca (11.0) with a mid-normal PTH 26). May be two processes at work. We'd need testing

Dropping PTH: PTH drops as calcium, vitamin D or both are increased.
