Individualization of lithium therapy based on the monitoring of its level in saliva.

Saliva in the monitoring of the lithium level is a promising biological material and offers the possibility to quickly estimate the individual lithium dosage for a specific patient which will provide the required therapeutic level. Saliva can be collected at home without the involvement of qualified personnel. Providing a more convenient and effective means of monitoring lithium therapy (e.g. the proposed non-invasive saliva level test) would enable safer, more effective therapy (more likely to maintain therapeutic blood levels) and an individualized therapeutic approach to a patient.
