Transport media have several applications including: 

• Transferring clinical specimens from collection center to diagnostic laboratories
• Preserving clinical specimens during delays, ensuring that they remain unaltered and viable for accurate laboratory evaluation notwithstanding any delay
• Providing the environment necessary to maintain the integrity of the culture while sharing or transferring microbial cultures highly sensitive to environmental changes
• Suppressing the growth of contaminants and other microbial species that are not of interest in clinical samples
• Maintaining the viability of certain organisms such as anaerobes, obligate pathogens, and fastidious organisms, which have specific requirements
• Transporting water, food, and other biological samples for analysis in order to obtain insights into water quality, food safety, and other important parameters.
