这是什么测试？

犬布氏杆菌IgG抗体检测是一项血液检测，用于测定血清中是否存在犬布氏杆菌（Brucella canis）的特异性IgG抗体。IgG抗体是感染后体内产生的免疫球蛋白，通常在感染后1-2周出现，并能长期存在于体内，因此这项检测可以帮助判断是否曾经感染或正在感染犬布氏杆菌。

为什么需要这项检测？

犬布氏杆菌是一种可由犬只传播给人类的细菌，会导致布氏杆菌病。该病常见症状包括发热、头痛、肌肉疼痛、疲劳等，严重的可能导致关节问题或生殖系统并发症。这项检测主要用于：诊断疑似布氏杆菌病；评估有相关症状或犬只接触史的人群；监测感染后的治疗效果。

如何进行检测？

检测需要抽取静脉血样。采血前无需特殊准备（如空腹）。血样将送往实验室进行分析，检测血清中是否存在犬布氏杆菌的IgG抗体。检测结果通常以阳性或阴性表示，也可能显示抗体滴度水平。

检测结果解读

阳性结果表示检测到IgG抗体，提示可能存在既往感染或现症感染。阴性结果表示未检测到抗体，可能意味着未感染、感染早期（抗体尚未产生）或感染已康复。医生会结合您的症状、接触史和其他检查结果来综合判断。

Reference range

Negative: <1:50 titer; Equivocal: 1:50-1:100; Positive: >1:100. Reference values may vary by laboratory and assay methodology.N/A

Specimen: serum

No special preparation required. Patient should inform clinician of any recent antibiotic use, as treatment may affect antibody titers. Acute and convalescent samples (2-4 weeks apart) are recommended for seroconversion assessment.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

这项检测需要空腹吗？
通常不需要空腹。您可以正常饮食后进行检测。
检测结果阳性意味着什么？
阳性结果表明您体内存在犬布氏杆菌IgG抗体，提示可能已经感染或曾经感染过该细菌。医生会结合您的症状和接触史进一步评估，必要时进行确诊试验或开始治疗。
阴性结果能完全排除感染吗？
不能完全排除。如果检测时间处于感染早期（2周内），抗体可能尚未产生，建议在2-4周后复查。如果有明确接触史或症状，仍需密切随访。
如何预防犬布氏杆菌感染？
预防措施包括：定期带宠物犬进行兽医检查；避免与流浪犬或不健康犬只密切接触；处理病犬分泌物时佩戴手套；养成良好的手部卫生习惯。免疫功能低下者应特别小心。
布氏杆菌病会人传人吗？
犬布氏杆菌人际传播极为罕见，主要传播途径是接触感染犬只或其分泌物（尿液、唾液、流产胎儿等）。
