CTX table

OK I found a table online that listed ranges for 'normal' , 'minimal to none' and moderate and high. The cutoff number appeared to be 299 even to reach a 'minimal' level if I recall correctly. It didn't list any age values there, but then again, I only looked at ONE chart.
They listed 300 to 600 as being in the normal range and there was a column that corresponded to the 'minimal' etc. that said 'risk of ONJ' which I should know, I suppose, but I will have to look up that abbreviated term as well ... as I said in another post, I'll go over results with the dr but meanwhile looking at the scores myself I didn't know what to think (390 now 340 or 343, about nine months later).
