1) What is dry ice?
Dry ice is solid Carbon Dioxide (CO2) with a low temperature of -78° C (-109° F). At atmospheric pressure, solid CO2 sublimates or changes directly to CO2 gas without a liquid phase.
2) How long are samples kept in dry ice? And does the long-term storage affect any sample analysis?
Samples can be kept frozen in dry ice for days, depending on the analytes/biomarker frozen stability. As dry ice has a limited shelf-life, long term storage of specimens can be jeopardized in case of insufficient replenishment of dry ice. For long term storage of specimens we recommend using a standard medical/scientific freezer instead of dry ice, with appropriate freezer’s temperature monitoring. Continue reading

Hemolysis is defined as the alteration, dissolution or destruction of red blood cell membranes in such a manner that hemoglobin is freed into the medium in which the cells are suspended. Hemolysis can be caused by antibodies, toxins, chemicals or physical stress from dilution, extremes of pressure, or shear forces or temperature during phlebotomy or preparation of serum. Even time can cause hemolysis, through the exhaustion of available glucose, which is necessary to maintain the fluidity and stability of the cell membranes. Continue reading
