概括
与直接测量相比,德隆,桑普森,马丁/霍普金斯和弗里德沃尔德公式可以准确估计低密度脂蛋白胆固醇 (LDL-C). 在哥伦比亚,Anandaraja和Cordova配方不推用于LDL-C估计.
科学领域:
- 心血管诊断心血管诊断服务
- 临床化学 临床化学
背景情况:
- 低密度脂蛋白胆固醇 (LDL-C) 的直接测量是可能的,但估计公式被广泛使用.
- 这些LDL-C估计公式的性能在哥伦比亚以前没有被评估过.
研究的目的:
- 通过使用各种估计公式,评估直接测量的LDL-C和计算的LDL-C之间的一致性.
- 在哥伦比亚人口中评估不同LDL-C估计方法的性能.
主要方法:
- 一项诊断测试研究,分析了从2014年至2022年期间的2,144个完整的脂质资料.
- 将直接的LDL-C测量与来自DeLong,Sampson,Friedewald,扩展的Martin/Hopkins,Anandaraja和Cordova公式的估计进行了比较.
- 使用林氏一致性相关系数 (CCC),布兰德-阿尔特曼图表和卡帕系数用于风险类别协议.
主要成果:
- 德隆 (CCC=0.971) 和桑普森 (CCC=0.969) 公式与直接的LDL-C测量显示了最高的一致性.
- 扩展的马丁/霍普金斯和弗里德沃尔德公式也表现良好 (CCC=0.964).
- 安纳达拉贾 (CCC=0.921) 和科尔多瓦 (CCC=0.881) 公式的一致性较低;高甘油三或低LDL-C水平的性能下降.
结论:
- 德隆,桑普森,扩展的马丁/霍普金斯和弗里德瓦尔德公式是哥伦比亚LDL-C估计的可靠方法.
- 在大多数临床场景中,这些公式表明可以与直接的LDL-C测量进行互换.
- 由于性能较差,不建议使用Anandaraja和Cordova配方.

Calibration Curves: Linear Least Squares
1.2K
A calibration curve is a plot of the instrument's response against a series of known concentrations of a substance. This curve is used to set the instrument response levels, using the substance and its concentrations as standards. Alternatively, or additionally, an equation is fitted to the calibration curve plot and subsequently used to calculate the unknown concentrations of other samples reliably.
For data that follow a straight line, the standard method for fitting is the linear...

Understanding serum lipids is crucial for maintaining cardiovascular health and preventing heart disease and stroke.
Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...
