What is a Specimen Bag?

A specimen bag is a flat poly bag specifically designed to store lab test results and keep them protected from leaks or contamination.

These types of bags are used by medical testing and research labs at facilities such as hospitals, environmental agencies, and universities. Other common names used for these poly bags are Laboratory Sample Bags or Biohazard Specimen Bags.

A Separate Compartment:

TDI’s Specimen Bags contain one compartment for test samples as well as a separate pocket for accompanying paperwork.

This extra pouch keeps documentation separated from the actual specimen, so it stays dry and clean. Also, it keeps paper files organized for easy access.

Special Handling Instructions:

Our poly bags have clear printed instructions on the outside, either on one side or on both sides. This makes it easy for staff to know what steps to take to process lab results. It greatly reduces the possibility of making errors in handling these delicate substances.

A Biohazard Symbol:

A biohazard symbol creates immediate identification for federal and OSHA requirements. Also, it is a clearly recognizable sign for staff to handle its contents with utmost care.

The sturdy poly material that these bags are made out of preventing leaks. It protects the specimen from outside contaminants such as dirt, dust, or moisture. On the other hand, it also prevents accidental infection with a virus or infectious diseases, such as HIV or measles.
