Precautions for using virus sampling tubes

Here are some precautions for using virus sampling tubes:

I. Before sampling

1. Choose the appropriate virus sampling tube: According to the detection purpose and sample type, select an inactivated or non-inactivated sampling tube. For example, for samples that need to be cultured for viruses later, a non-inactivated sampling tube should be selected; if only nucleic acid detection is performed, an inactivated sampling tube can be selected to reduce the risk of biosafety.
2. Check the integrity of the sampling tube: Before use, carefully check whether the packaging of the sampling tube is intact, and whether there are any damages or leaks in the tube body. If there is a problem, it should be replaced in time.

II. During sampling

1. Strict aseptic operation: Sampling personnel should wear appropriate personal protective equipment such as gloves, masks, and goggles, and strictly follow aseptic operation specifications to avoid sample contamination.
2. Correctly collect samples: According to the prescribed sampling method, accurately collect samples. For example, when collecting throat swabs, the swab should be inserted deep into the pharynx and wipe the tonsils on both sides and the posterior pharyngeal wall to avoid touching other parts such as the tongue.
3. Avoid cross-contamination between samples: Use disposable sampling swabs. After collecting each sample, the swab should be replaced in time to avoid cross-contamination between different samples.

III. After sampling

1. Seal the sampling tube in time: After collecting the sample, immediately close the cap of the sampling tube tightly to ensure good sealing and prevent sample leakage and external contamination.
2. Correctly mark the sampling information: Clearly mark the source, collection time, and collector of the sample on the sampling tube for subsequent detection and tracing.
3. Properly store and transport: According to the storage requirements of the sampling tube, place it under appropriate temperature and environment for storage. During transportation, avoid the sampling tube being affected by severe vibration, high temperature, direct sunlight, etc., to ensure the stability of the sample.

IV. Other precautions

1. Comply with biosafety regulations: During the use of virus sampling tubes, biosafety regulations should be strictly complied with, and used sampling tubes and related wastes should be properly disposed of to avoid harm to the environment and personnel.
2. Pay attention to the expiration date: Different types of virus sampling tubes may have different expiration dates. Detection should be carried out within the specified time to avoid sample expiration.
3. Training and guidance: Sampling personnel should receive professional training and guidance, be familiar with the use methods and precautions of virus sampling tubes, and ensure the accuracy and safety of the sampling process.
