Monitoring prescribed doses of medication

We support clinicians and pharmacists with quick and accurate analytical results to ensure patients are receiving the right dose of a prescription medicine.

We specialise in testing for:

    • antipsychotic drugs, including clozapine
    • immunosuppressants

Our therapeutic drug monitoring provision continues to grow. Contact us for the latest update.

Our clozapine testing service has its own dedicated secure website.

Registered customers can access their patients’ results and review trends via our dedicated and fully encrypted microsite: We offer advice and educational training seminars free of charge, drawing upon our extensive experience and relevant research.

The results are emailed directly to me, which is very useful
We value ASI’s independent professional service, unrivalled experience and expertise in all aspects of immunosuppressive drug testing.
