I got my labs and there are some new things checked. One is a PMP Panel 15. The Laboratory is Solstas that takes my blood, urine, and sometimes air to check my levels. I usely have about 19 things checked, but this time there are more. I looked up PMP 15 panel, and it talks about LC-MS/MS testing. Exactly what is that used for? It seems like a data base to keep track of ppl. An urinalysis, comp is already checked so is this more urine or blood? Or is it both? I just wanna know why & how it's completed. I don't u understand how liquid chromatography mass spectrum is performed. Seems like it's to monitor ppl, and I'm all for that but it's confusing about how they dissect the patients labs, and how the data is collected and stored. I take all my meds, but if it says 2-4 a day I might take 2 and only more if needed. If it's gonna show that my levels are low I'll take more but rather keep doing it how it's written. Can anyone tell me how it works, how, and why? Ty
