U.S., May 5 -- ClinicalTrials.gov registry received information related to the study (NCT07565064) titled 'ALPCO 25(OH) Vitamin D CLIA Kit - Fresh Versus Frozen Serum and Plasma Stability Study' on April 27.
Brief Summary: This study evaluates the stability of 25-hydroxyvitamin D [25(OH)D] measurements in human serum and plasma using the ALPCO 25(OH) Vitamin D CLIA Kit. The study compares results obtained from fresh specimens with those obtained after storage under various temperature and time conditions, including long-term frozen storage and short-term handling scenarios. The objective is to demonstrate that specimen storage conditions do not result in clinically meaningful differences in measured 25(OH)D concentrations, supporting the u...
