Clinical context

Clinical testing guide & how to choose

Tests in Therapeutic Drug Monitoring answer different clinical questions. This catalogue supports a conversation with your clinician or counselor; it does not establish a diagnosis or replace an individual assessment.

Choosing a test

A comprehensive panel measures several related markers, while a single-marker test addresses a more focused question. A larger panel is not automatically the right choice. Discuss your symptoms, previous results and referral with a qualified clinician before selecting tests. Results should not be interpreted in isolation.

Before sample collection

Confirm the required tube, sample volume, any fasting instructions and the collection deadline for your chosen test. Tell the collection team about medication and recent treatment. Do not stop prescribed medication unless your clinician advises it. Home collection depends on the sample’s handling and transport requirements.

Common questions

Questions before booking

Should I choose a panel or a single-marker test for Therapeutic Drug Monitoring?

A comprehensive panel measures several related markers, while a single-marker test addresses a more focused question. A larger panel is not automatically the right choice. Discuss your symptoms, previous results and referral with a qualified clinician before selecting tests. Results should not be interpreted in isolation. Free pre-test counselor guidance is available to help you understand the booking options.

Can I use SHIF/SHA or private insurance for these tests?

Coverage depends on your scheme, the specific test, referral and authorization requirements, and the provider arrangement. Before booking, ask the laboratory and your insurer to verify eligibility, any co-payment, and whether direct billing or reimbursement applies. Listing a test here does not guarantee insurance coverage.

When should I arrange sample collection?

Check the sample and preparation notes for the specific test, then confirm the collection time and reporting deadline with the laboratory. Same-day reporting, where listed, may depend on a collection cutoff and working days. Nationwide and home sample collection are available subject to location, sample suitability and transport arrangements.
