A Certified Spiking Solution® for use in therapeutic drug monitoring (TDM) analyses by HPLC or LC/MS. Used in the treatment of cancer and autoimmune diseases, methotrexate is an antimetabolite and antifolate drug monitored by clinical labs to ensure patients remain within the drug’s therapeutic range. The Snap-N-Spike® format allows laboratories to eliminate weighing operations of hazardous substances such as methotrexate, significantly reducing occupational exposure hazards related to handling of acutely toxic powders, and provides the ability to spike into their matrix of choice just before use.
