C反应蛋白(CRP)浊度法测定
这项检查测量血液中C反应蛋白的水平,它是炎症的标志物。它可以帮助医生评估您是否存在持续的炎症状况或对感染的炎症反应。

- 检测方法
- Flow cytometry using fluorescently labeled monoclonal antibodies against CD19 (pan-B-cell marker) and CD79b (B-cell receptor component). Cells are identified by dual-positive fluorescence emission detected via multiparameter flow cytometric analysis.

- 标本量
- 3-5 mL of whole blood for adults; minimum 1 mL for pediatric specimens. Higher volumes preferred for absolute count accuracy.
- 标本稳定性
- Specimen should be processed within 24 hours of collection when stored at room temperature (18-22°C). Refrigeration (2-8°C) may extend stability to 48 hours for some markers but can affect cell viability and fluorescence intensity. Samples should not be frozen.

什么是C反应蛋白?
C反应蛋白(CRP)是您的肝脏在炎症反应中产生的一种蛋白质。当您的身体对抗感染、损伤或其他炎症过程时,它的水平会升高。虽然CRP本身并无害处,但它的存在表明您的免疫系统处于活跃状态。
医生为什么会开具这项检查?
医生可能会开具CRP检查来评估发热、关节疼痛或不明原因肿胀等症状。它也用于筛查心脏病、自身免疫性疾病或感染等疾病。有些检查会在手术前检测CRP水平,或用于监测类风湿关节炎等慢性疾病。
检查是如何进行的?
通常从您手臂的静脉采集血样。样本会被送往实验室,采用浊度法分析以测量CRP水平。整个过程很快,通常不需要特殊准备。
结果意味着什么?
结果以毫克每分升(mg/dL)为单位报告。水平较高可能提示炎症、感染或其他健康问题。医生会结合您的症状、病史和其他检查来解读结果。
Reference range
Reference ranges vary by laboratory, instrument, and antibody clone. Absolute count typically reported as cells/μL; relative percentage as % of total lymphocytes or leukocytes. Adult reference intervals are generally established locally; published studies suggest CD19+CD79b+ B-cell populations constitute approximately 5-15% of peripheral blood lymphocytes in healthy adults. Pediatric values may differ.N/A
No special patient preparation required. Recent immunosuppressive therapy, chemotherapy, corticosteroid use, or B-cell-targeted biologics (rituximab, obinutuzumab) may significantly alter results and should be documented. Specimen should be processed within 24 hours of collection for optimal viability.
