眼液和血清之间的协议用于检测狗的尿素和肌素
Journal of the American Veterinary Medical Association
|July 26, 2024
概括
眼液尿素水平与狗的血清水平非常接近,这表明一种潜在的非侵入性诊断替代方案. 然而,眼液中的肌素测量显示与血清的一致性较差,限制了其诊断效用.
科学领域:
- 在兽医中比较生物化学.
- 对系统性疾病标志物的眼液分析.
- 诊断生物标志物验证的验证
背景情况:
- 血清生物化学分析是诊断亚热血症和监测狗功能的标准.
- 非侵入性采样方法是可取的,以减少患者的压力,并提高诊断的可访问性.
- 眼液 (LF) 是一种易于获得的生物流体,可能反映系统代谢物度.
研究的目的:
- 为了比较尿素和肌素水平在液 (LF) 与血清 (SER) 在健康 (对照) 和亚体狗.
- 评估这些分析物的LF和SER测量之间的一致性.
- 评估LF作为SER替代品在诊断尿血病中的潜力.
主要方法:
- 一项前性观察性研究,涉及40只对照犬和38只阿佐特犬.
- 每只眼睛收集20μL的眼液和3mL的血,用于血清.
- 使用布兰德-阿尔特曼图表和类内相关系数 (ICC) 分析协议.
主要成果:
- 在控制组 (ICC=0.874) 和亚组 (ICC=0.82) 中,在尿素中观察到LF和SER之间的良好一致性.
- 在两组中,LF和SER之间的肌素一致性很差.
- 只有26只狗的肺炎中可以检测到肌素,这表明灵敏度低.
结论:
- 眼液尿素度与狗的血清水平有很好的一致性,不论其酸性状况如何.
- 眼液中的肌氨酸度与血清度不太一致.
- LF尿素可以作为诊断尿素病的血清的非侵入性替代品,但需要进一步的研究.

Drug Dosing in Renal Diseases: Measurement of Glomerular Filtration Rate
The glomerular filtration rate (GFR) is a critical indicator of kidney health, reflecting how well the kidneys filter blood. Changes in GFR can signal potential kidney impairment, necessitating accurate measurement methods to monitor kidney function effectively.Various molecules can serve as markers for GFR measurement, with the ideal marker meeting several specific criteria. It must freely filter at the glomerulus, avoid reabsorption or secretion by the renal tubules, remain unmetabolized, not...
Drug Dosing in Renal Diseases: Measurement of Serum Creatinine Concentration and Clearance
In healthy individuals, serum creatinine levels remain stable due to a balance between its constant production—primarily from muscle metabolism—and renal excretion. Creatinine is freely filtered by the glomeruli, making it a valuable marker for estimating renal function. When the glomerular filtration rate (GFR) decreases, the kidneys can only eliminate less creatinine, causing serum levels to rise.Serum creatinine concentration is widely used to estimate creatinine clearance (Clcr), a...
Drug Dosing in Renal Diseases: Estimation of Glomerular Filtration Rate Based on Serum Creatinine Concentration
Glomerular filtration rate (GFR) can be estimated from serum creatinine using the modification of diet in renal disease (MDRD) formula or the chronic kidney disease–epidemiology collaboration (CKD–EPI) equation. Both methods are widely used in clinical practice to assess kidney function and guide treatment decisions.The MDRD equation does not require weight or height measurements and is normalized to the body surface area of 1.73 m², considered the average adult surface area. This equation is...
Urine Studies I: Urinalysis
Urinalysis is a widely used diagnostic test that analyzes urine's physical, chemical, and microscopic characteristics. Healthcare providers use it to detect and monitor various health conditions, including renal disease, urinary tract infections (UTIs), diabetes, and metabolic or systemic disorders.Components of UrinalysisUrinalysis consists of three primary components: physical, chemical, and microscopic examination. Each provides unique insights into the urine sample and, by extension, the...
Serum Studies: Renal Function Tests
Renal function tests are crucial for assessing kidney health, monitoring disease progression, and evaluating the kidneys' efficiency in waste elimination, fluid balance, and electrolyte regulation. These tests offer critical insights into kidney function, even though routine measurements may appear normal until there is a significant decline in the glomerular filtration rate or GFR. Typically, signs of kidney impairment only become evident when the GFR falls to about 50% of its normal level.
