Feeling stupid and I thought I was good at math
HOW do I figure out the 1 to 10 ratio?

My p1np is 37
CTX is 336
Not on any meds yet
Starting soon very likely

Keep it simple. Divide CTX by PINP. For you that number is 9.08 which is essentially equal to the "magic" 10:1 ratio. If you blindly accept these ratios, my value of 4.2 should mean I do not have osteoporosis but I do.

Don't feel bad. It took me a long time to remember how to calculate ratios. I was really frustrated. Thankfully, Google was a big help.

Based on your CTx of 336 and P1NP of 37, your ratio is 10:1.1. This is a great ratio for maintaining bone health. Many factors influence bone turnover, so it's hard to say why your numbers were good on that particular day. Considering you have osteoporosis, this hasn't always been the case. It could have been a one-time thing, so take these numbers as just a snapshot

Here's the calculation
CTx/P1NP = 10/x.
336/37 = 10/x
10 ÷ (336/37) = x
10/9.08 = 1.1
x = 1.1
Resulting ration 10 : 1.1
