- 标本量
- 3-5 mL of whole blood for adults; minimum 1 mL for pediatric patients. Specimen volume requirements vary by laboratory; contact testing facility for specific requirements.
- 标本稳定性
- Specimen should be processed within 24-48 hours of collection when stored at room temperature (18-25°C). Refrigeration (2-8°C) may extend stability up to 72 hours for some markers, but CD26 expression can be affected by prolonged storage. Optimal results obtained within 24 hours of collection.

为什么要做这项检查
医生可能会开具这项检查,以排查头痛、颈部僵硬、癫痫发作、意识模糊或神经系统问题等症状。它也用于监测中枢神经系统的感染、炎症或肿瘤等疾病。
检查前需要做什么准备
无需特殊准备。检查后您可能会有轻微头痛,但通常很快就会消失。如果您正在服用抗凝药物或有出血性疾病,请在操作前告知医生。
检查是如何进行的
医生通过将针插入您的脊柱(腰椎穿刺)采集少量脑脊液。随后将样本送至实验室进行显微镜检查,以计数并识别不同类型的细胞,包括红细胞。
结果意味着什么
结果异常可能提示感染(如脑膜炎)、出血、炎症或其他神经系统疾病。医生会结合您的症状和病史来解读结果。
Reference range
Reference ranges for CD2+CD26+ cells vary by laboratory and reference population. Typically reported as a percentage of total lymphocytes or as absolute count per microliter of blood. Values are generally established through flow cytometric immunophenotyping with CD45 gating and lymphocyte subset analysis.N/A
No special patient preparation required. Patient should be well-hydrated. Inform the laboratory of any recent infections, immunosuppressive therapy, corticosteroid use, chemotherapy, or hematopoietic stem cell transplantation, as these factors may affect lymphocyte subset distribution.
