Intended Use
The DSL ACTIVE CrossLaps™ ELISA assay is intended for the quantitative determination of CrossLaps™ in human urine. The measurement of CrossLaps™ is used as an indicator of human bone resorption.
Device Story
In vitro diagnostic ELISA kit; competitive binding protein assay. Input: human urine sample. Mechanism: CrossLaps™ in sample competes with antigen-coated microtitration wells for enzyme-labeled CrossLaps™ antibody; separation via aspiration and washing; spectrophotometric analysis of bound absorbance. Output: quantitative concentration of CrossLaps™ (inversely proportional to absorbance). Used in clinical laboratory settings by trained technicians. Results assist clinicians in assessing bone resorption rates, aiding in the management of metabolic bone diseases.
Clinical Evidence
Bench testing only. Comparative study of 60 human urine samples using both DSL ACTIVE CrossLaps™ ELISA and OSTEX OSTEOMARK assay. Linear regression analysis: Y = 3.18(X) + 16.69; correlation coefficient (r) = 0.95.
Technological Characteristics
Competitive enzyme-linked immunosorbent assay (ELISA). Components: microtitration wells coated with antigen, enzyme-labeled CrossLaps™ antibody. Detection: spectrophotometric absorbance measurement. Format: 96-well microtiter plate.
Indications for Use
Indicated for the quantitative measurement of Type I Collagen Telopeptide (CrossLaps™) in human urine as an indicator of bone resorption in humans.
Regulatory Classification
Identification
A hydroxyproline test system is a device intended to measure the amino acid hydroxyproline in urine. Hydroxyproline measurements are used in the diagnosis and treatment of various collagen (connective tissue) diseases, bone disease such as Paget's disease, and endocrine disorders such as hyperparathyroidism and hyperthyroidism.
