Magna Laboratories™ is the sister company of Leyden Delta™, the largest supplier of clozapine in the UK and was created in order to provide a Central Pathology Service for treatment services using Leyden Delta’s brand of clozapine , Zaponex™ (clozapine). As a result, Magna Laboratories™ has a direct interface with ZTAS™, Leyden Delta’s Patient Monitoring System and very close contacts with their Drug Safety and Medical Information departments in order to deliver a seamless service for their patients and those caring for them. Magna Laboratories™ first FBC samples were processed in November 2011 and less than a year later the clozapine plasma levels were analysed. Since then Magna lLaboratories™ has grown to meet not only the needs of both Leyden Delta™ but also the needs of those treating clozapine patients.
