What are specimen bags used for?

In the fields of medicine, research, and the environment, specimen bags are utilized for the purpose of transporting and storing biological samples in a protected and reliable manner. These samples can include blood, urine, tissues, swabs, and other physiological fluids that have been collected for analysis in a laboratory setting.


The following are the principal uses for specimen bags:

  • Containment: They provide a secure environment to avoid the leaking or spilling of specimens, which could be harmful. This is accomplished by containing the specimen to be shielded from outside containments and to keep the handlers safe as well.
  • Protection: They guard the sample against contamination by outside substances or environmental conditions, both of which have the potential to affect the results of a test.
  • Safety: Individuals who handle the samples are shielded from the risk of infection or exposure to other harmful substances due to these procedures.
  • Labeling and Documentation: Specimen bags often but not always feature a separate pocket or an attached document pouch that enables the addition of paperwork, such as lab requisition forms, without the risk of the paperwork becoming compromised by the sample. This makes it possible to include the documentation in the sample without undermining the integrity of the sample.
  • Compliance: Appropriate specimen handling, which may include the utilization of specimen bags, is frequently required to comply with various health and safety requirements and laboratory accreditation criteria.


To protect the integrity of the sample from the time it is collected until it is analyzed, specimens are stored in bags that are made of plastic. These bags are designed to be long-lasting and, in some cases, tamper-evident. They are an integral component of the biohazard handling protocols that govern the safe transportation of potentially infectious or hazardous samples. These protocols were developed to keep people safe while transporting potentially contagious or harmful materials.
