英文回答：
Diagnosis of Good's syndrome requires the presence of both thymoma and hypogammaglobulinemia. Thymoma is a tumor of the thymus gland, which is an important part of the immune system. Hypogammaglobulinemia refers to a deficiency of gamma globulins, which are a type of antibody that helps the body fight infections.
In addition to these two main criteria, patients with Good's syndrome often present with recurrent infections, particularly of the respiratory tract, as well as other autoimmune conditions such as autoimmune cytopenias and inflammatory bowel disease. The combination of these symptoms along with the presence of thymoma and hypogammaglobulinemia is highly suggestive of Good's syndrome.
Laboratory tests play a crucial role in the diagnosis
of Good's syndrome. This includes measuring the levels of different types of immunoglobulins, particularly IgG, IgA, and IgM. A marked reduction in these levels, especially in the presence of recurrent infections, can raise suspicion for Good's syndrome. Additionally, a biopsy of the thymoma may be performed to confirm its presence.
It is important to differentiate Good's syndrome from other causes of hypogammaglobulinemia, such as common variable immunodeficiency (CVID) or X-linked agammaglobulinemia. This can be done through a thorough evaluation of the patient's medical history, physical examination, and laboratory tests.
In summary, the diagnosis of Good's syndrome requires the presence of thymoma and hypogammaglobulinemia, along with a history of recurrent infections and possibly other autoimmune conditions. Laboratory tests and biopsy of the thymoma are essential for confirming the diagnosis.

Good综合征的诊断需要同时具备胸腺瘤和低免疫球蛋白血症的特征。

胸腺瘤是胸腺腺体的肿瘤，它是免疫系统的重要组成部分。

低免疫球蛋白血症指的是γ球蛋白的缺乏，γ球蛋白是一种帮助身体抵抗感染的抗体。

除了这两个主要标准外，患有Good综合征的患者通常表现为反复感染，特别是呼吸道感染，以及其他自身免疫疾病，如自身免疫性细胞减少症和炎症性肠病。

这些症状与胸腺瘤和低免疫球蛋白血症的存在结合在一起，高度提示了Good综合征的可能性。

实验室检测在Good综合征的诊断中起着至关重要的作用。

这包括测量不同类型的免疫球蛋白的水平，特别是IgG、IgA和IgM。

这些水平的显著降低，特别是伴随反复感染，可能会引起对Good综合征的怀疑。

此外，可能会进行胸腺瘤的活检以确认其存在。

重要的是要区分Good综合征与低免疫球蛋白血症的其他原因，如常见变量免疫缺陷（CVID）或X连锁无γ球蛋白血症。

这可以通过对患者的病史、体格检查和实验室检测进行彻底评估来完成。

总之，Good综合征的诊断需要具备胸腺瘤和低免疫球蛋白血症的特征，以及反复感染的病史，可能还伴有其他自身免疫疾病。

实验室检测和胸腺瘤活检对确认诊断至关重要。
