Longhorn Vaccines and Diagnostic recalls PS-MTM tubes (models LH-1-2 to LH-1-15CC) that may lack labels. Without labels, users can't identify tubes, and if samples are tested with bleach-containing reagents, cyanide gas may form. Affected lab users should check labels and avoid using unlabeled tubes.
The tubes may have been delivered to some users without labels. Users may not be able to identify the tubes without these labels. If samples stored or transported in tubes are tested on certain systems or come into contact with bleach they can produce cyanide gas. The solution in these tubes contains guanidine thiocynate and may put laboratory personnel at risk of exposure to cyanide gas when it comes into contact with bleach or reagents containing bleach.
