The DART study – a precision medicine approach to reducing treatment burden, cost and side effects

Tuesday October 27th, 2026 - 12pm ET, 5pm BST, 5pm CET

DBS PostAl remote immunoglobulin ReplacemenT monitoring (DART) Study Project

Dried blood spot (DBS) testing is a well-established method used for serological analysis, including infectious disease screening, autoantibody detection, and measurement of immunoglobulins. DBS samples are collected via a simple finger-prick, with blood applied to filter paper, dried, and posted to the laboratory without special transport requirements. Samples remain stable at room temperature for several days, and recent volumetric collection devices have improved analytical accuracy.

Compared with conventional venous blood sampling, DBS reduces the need for hospital visits, phlebotomy services, specialized transport, and associated costs, while improving patient convenience.

The DART study evaluated the accuracy and acceptability of DBS testing for monitoring IgG levels in patients with antibody deficiency receiving immunoglobulin replacement therapy (IgRT) across Wales. DBS results were compared with conventional blood samples over 12 months, alongside patient questionnaires assessing acceptability and potential reduction in treatment burden.

What you will learn

You will learn how dried blood spot (DBS) testing can be used to monitor IgG levels and how its accuracy compares with conventional venous sampling. The webinar also explores its potential to reduce patient burden, clinic visits, and healthcare resource use.
