CTX Biomarker

Meaning

The CTX Biomarker, specifically the C-terminal telopeptide of type I collagen, is a measurable biochemical fragment utilized in clinical practice to quantify the current rate of bone resorption, or breakdown, within the skeletal system. Elevated concentrations of CTX in the serum or urine are a direct indicator of heightened osteoclast activity, reflecting a rapid turnover of bone tissue. This measurement is indispensable in hormonal health for monitoring the skeletal effects of fluctuating estrogen, testosterone, and parathyroid hormone levels, particularly in the context of osteoporosis management.
