General specimen container IVD, additive/medium

General specimen containers with additives or media are single-use devices designed to collect, preserve, and transport multiple types of clinical specimens—such as urine, stool, or respiratory samples—for diagnostic testing. These containers often include preservatives or microbiological media to maintain specimen integrity during transport, enabling accurate in vitro diagnostics like nucleic acid testing, microbial culture, or histopathology.

These devices are typically regulated as in vitro diagnostics (IVDs) and are supplied sterile, ready for immediate use. They are not intended for repeated use or direct patient contact beyond specimen collection, adhering to single-use standards. Classification and supply vary by jurisdiction, but they are widely used in clinical, research, and public health settings for specimen handling.
