True or False: Frozen specimens must be transported on dry ice.

Frozen specimens indeed must be transported on dry ice, and this is crucial for several reasons. When biological specimens are frozen, they need to remain at low temperatures to preserve their integrity and prevent degradation or alteration in their properties. Dry ice, which is solid carbon dioxide, maintains a temperature of -78.5 degrees Celsius (-109.3 degrees Fahrenheit), making it an ideal medium for keeping specimens frozen during transportation. This is especially important in the context of specimens that are sensitive to temperature changes, such as certain blood components, tissue samples, or microbiological cultures.

Transporting these specimens without maintaining the necessary low temperature could compromise test results, hinder accurate diagnosis, or render the specimen unusable, thus affecting patient care and research outcomes. Therefore, to ensure quality and reliability, the use of dry ice for transporting frozen specimens is accepted as standard practice in laboratory settings and healthcare environments.
