- 常规的dithiothreitol (DTT) 处理用于吐细胞学是为评估气道异敏性建立的.
- 多步骤的DTT协议资源密集,限制了其临床使用.
- 固定在甲上,嵌入 (FFPE) 的唾液塞提供了一个潜在的简化替代方案.
研究的目的:
- 评价FFPE唾液塞作为测量气道异敏的简化方法.
- 为了比较SSIMPLE方法与传统DTT处理的有效性.
- 评估SSIMPLE方法在复杂的呼吸道疾病和治疗监测中的可靠性.
主要方法:
- 唾液最小化处理,最大限度地提高临床结果 (SSIMPLE) 方法涉及将唾液固定在甲素中,并嵌入在抛中.
- FFPE块被切割,染色,并由盲目观察者分析差异细胞计数.
- 来自SSIMPLE的乙氨基酸比例与匹配的DTT处理样本进行了比较.
主要成果:
- 96%的FFPE幻灯片足以进行分析,90%与DTT样本相匹配.
- 通过SSIMPLE方法,观察者之间的可重复性非常出色 (一致性:0.975;一致性:0.976).
- 乙素比例显示出显著的相关性 (ρ=0.9) 和与DTT处理的一致性,曲线下面积高 (0.957).

Sputum Studies I: Gram Stain, cytology, and Acid-fast smear and culture
563
Sputum studies are a critical part of diagnosing and treating numerous respiratory conditions. These studies involve obtaining sputum samples for analysis to identify pathogenic organisms and assess the presence of abnormal cells indicative of malignant conditions. This lesson will delve into three fundamental sputum studies: Gram Stain, Cytology, and Acid-fast Smear and Culture.

Sputum Studies II: Culture and Sensitivity
1.1K
Description
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
