The Urine CrossLaps® (CTX-I) EIA is an enzyme immunosorbent assay for quantitative determination of degradation products of C-terminal telopeptides of Type-I collagen in human urine.

The Urine CrossLaps® (CTX-I) EIA assay is intended for in vitro diagnostic use as an indication of human bone resorption and may be used as an aid in:
Monitoring bone resorption changes of:

Anti-resorptive therapies in postmenopausal women:

  • Hormone Replacement Therapies (HRT) with hormones and hormone-like drugs
  • Bisphosphonate therapies

Anti-resorptive therapies in individuals diagnosed with osteopenia:

  • Hormone Replacement Therapies (HRT) with hormones and hormone-like drugs
  • Bisphosphonate therapies.

Predicting skeletal response (Bone Mineral Density) in postmenopausal women undergoing anti-resorptive therapies:

  1. Hormone Replacement Therapies (HRT) with hormones and hormone-like drugs
  2. Bisphosphonate

Type I collagen accounts for more than 90% of the organic matrix of bone and is synthesised primarily in bone.

During renewal of the skeleton, Type I collagen is degraded, and small peptide fragments are excreted into the urine. These fragments can be measured by Urine CrossLaps® (CTX-I) EIA as has been reported as useful for follow up of anti-resorptive treatment of patients with metabolic bone diseases 1, 2, 3.
