腺病毒是一組常見病毒，會引起多種疾病, 包括呼吸道和胃腸道感染. 採集檢體進行腺病毒檢測對於準確診斷和有效治療至關重要. 在本文中, 我們將討論安全有效的腺病毒標本採集方法, 確保醫療保健專業人員和患者的福祉.

準備標本採集:

Before collecting adenovirus specimens, it is essential to gather the necessary equipment and maintain proper hygiene. Follow these steps:

1. Wear appropriate personal protective equipment (個人防護裝備): Put on disposable gloves, a gown, and a face mask to protect yourself from potential exposure.

2. Gather supplies: Collect sterile swabs, viral transport media tubes, and biohazard bags for proper specimen storage and transportation.

3. 手部衛生: Wash your hands thoroughly with soap and water or use an alcohol-based hand sanitizer before and after each collection.

Specimen Collection Procedure

Adenovirus specimens can be collected through various methods, including nasal swabs, 咽拭子, fecal specimens, and eye swabs, depending on the specific symptoms and suspected site of infection.

1. Nasopharyngeal Specimen Collection

For respiratory adenovirus infections, A 鼻咽拭子 is commonly used. To collect the specimen safely and effectively, 按著這些次序:

A. Gently insert a flexible, sterile swab into the nostril until resistance is met at the nasopharynx.
乙. Rotate the swab several times to obtain an adequate sample.
C. Carefully remove the swab without touching any other surfaces or objects.
d. Place the swab into a sterile tube containing a viral transport medium, 確保其正確密封.

2. Throat Specimen Collection

In cases where a nasopharyngeal swab is not feasible, A 咽拭子 can be used to collect adenovirus specimens. The following guidelines should be followed:

A. Tilt the patient’s head back slightly and ask them to open their mouth wide.
乙. With a sterile swab, gently swipe the back of the throat, targeting the tonsils and any visible lesions.
C. 避免接觸舌頭, 牙齒, or cheeks.
d. Place the swab into a sterile tube containing a viral transport medium, ensuring proper sealing.

3. Eye Specimen Collection

For ocular adenovirus infections, conjunctival swabs are employed. Here’s how to collect the specimen safely:

A. Wash your hands and put on sterile gloves.
乙. Gently roll a sterile swab over the conjunctiva of the affected eye, avoiding direct contact with the cornea.
C. Place the swab into a sterile tube containing a viral transport medium, ensuring proper sealing.

4. Post-collection Precautions

After completing the specimen collection, it is essential to observe proper disposal and hygiene practices:

A. Remove PPE: Safely remove and dispose of all PPE following the recommended guidelines.
乙. 手部衛生: 用肥皂和水徹底洗手或使用酒精類洗手液.
C. Clean the collection area: Disinfect any surfaces or equipment used during the procedure to prevent cross-contamination.
