Infection Specimen Collection Procedure.
Introduction.
Collection of infection specimens is crucial for accurate diagnosis and appropriate treatment of infectious diseases. The correct collection and handling of specimens is essential to ensure optimal results and patient safety. This document outlines the general procedure for collecting infection specimens, including types of specimens, collection techniques, and specimen handling.
Types of Infection Specimens.
The type of specimen collected depends on the suspected infection and the specific diagnostic test being performed. Common types of infection specimens include:
Blood: Used for bacterial, viral, and fungal cultures, serology tests, and molecular diagnostics.
Urine: Used for urinary tract infections, sexually transmitted infections, and some systemic infections.
Stool: Used for gastrointestinal infections, parasites, and ova and cysts.
Sputum: Used for respiratory tract infections.
Wound swabs: Used for skin and soft tissue infections.
Cerebrospinal fluid (CSF): Used for meningitis, encephalitis, and other central nervous system infections.
Collection Techniques.
The collection technique varies depending on the type
of specimen. General principles for specimen collection include:
Use sterile containers: Use sterile, leak-proof containers provided by the laboratory.
Collect at the appropriate site: Collect specimens from the site where the infection is suspected.
Obtain sufficient volume: Collect an adequate amount of specimen for the required tests.
Avoid contamination: Prevent contamination of the specimen with other substances, such as saliva or skin flora.
Specific collection techniques for different specimen types include:
Blood: Collected from a vein using a sterile needle and syringe.
Urine: Collected midstream in a sterile container.
Stool: Collected in a sterile container without additives.
Sputum: Collected by coughing deeply into a sterile container.
Wound swabs: Collected by gently rotating a sterile swab over the wound surface.
Cerebrospinal fluid: Collected from the lumbar space using a sterile needle and syringe.
Specimen Handling.
Once collected, specimens should be properly handled to preserve their integrity and prevent contamination. General principles for specimen handling include:
Label specimens: Clearly label containers with the patient's name, date of collection, and specimen type.
Transport promptly: Transport specimens to the
laboratory as soon as possible.
Keep specimens refrigerated: Refrigerate specimens at 2-8°C if not processed immediately.
Follow laboratory instructions: Adhere to the laboratory's specific instructions for specimen handling and transport.
Conclusion.
Adherence to proper infection specimen collection and handling procedures is essential for accurate diagnosis and appropriate treatment of infectious diseases. By following these guidelines, healthcare professionals can ensure the collection of high-quality specimens that will contribute to optimal patient outcomes.

感染性标本的类型。

采集的标本类型取决于疑似感染和正在进行的具体诊断测试。

常见的感染性标本类型包括：
血液，用于细菌、病毒和真菌培养、血清学测试和分子诊断。

尿液，用于尿路感染、性传播感染和一些全身感染。

粪便，用于胃肠道感染、寄生虫和卵囊和包囊。

痰液，用于呼吸道感染。

伤口拭子，用于皮肤和软组织感染。

脑脊液（CSF），用于脑膜炎、脑炎和其他中枢神经系统感染。

采集技术。

采集技术因标本类型而异。

标本采集的一般原则包括：
使用无菌容器，使用实验室提供的无菌防漏容器。

在适当的位置采集，从怀疑感染的位置采集标本。

获得足够量，采集足够量的标本，以满足所需测试的要求。

避免污染，防止标本被其他物质（如唾液或皮肤菌群）污染。

针对不同标本类型的具体采集技术包括：
血液，使用无菌针筒和注射器从静脉采集。

尿液，在中段尿中收集到无菌容器中。

粪便，收集在不含添加剂的无菌容器中。

痰液，通过深咳收集到无菌容器中。

伤口拭子，通过在伤口表面轻轻旋转无菌拭子来采集。

脑脊液，使用无菌针筒和注射器从腰椎间隙收集。

标本处理。

收集后，应正确处理标本，以保持其完整性并防止污染。

标本
处理的一般原则包括：
标注标本，在容器上清楚地标注患者姓名、采集日期和标本类型。
