Under what circumstances is a sample transport bag typically used?

Sample transport bag is commonly used for the transportation and preservation of clinical test

samples, collection and transport of forensic samples, and gathering and transport of scientific research

samples. Specific scenarios include:

Transportation and Preservation of Clinical Test Samples:

During clinical diagnosis and treatment, various biological samples such as blood, urine, feces, cerebrospinal fluid, serous cavity effusion, nasal/throat swabs, and pathological tissues need to be safely transported from the collection site to the laboratory for testing[^1^]. In these instances, sample transport bags not only protect the samples from external contamination but also ensure that pathogens in the samples do not pose a hazard to the environment and personnel.

Collection and Transport of Forensic Samples:

In crime scene investigations, forensic personnel need to collect bloodstains, body fluids, tissues, and other physical evidence, and safely transport these samples to the laboratory for analysis. Sample transport bags play a crucial protective role in this process, ensuring that the samples are not contaminated and that the integrity and reliability of the evidence are maintained[^3^].

Collection and Transport of Scientific Research Samples:

Researchers in fields such as biology, genetics, and environmental science also need to use sample transport bags when collecting samples in the field. These samples may include animal and plant tissues, soil, water bodies, etc., which need to be transported back to the laboratory for analysis under contamination-free conditions. Sample transport bags can effectively prevent biological samples from physical damage or temperature changes during transport[^2^].

In summary, sample transport bag play a vital role in modern medical, forensic, and scientific research

fields. Their design and usage standards ensure the integrity and safety of the samples, thereby

guaranteeing the accuracy and reliability of experimental results.
