Spot. Screen. Support.
Inborn Errors of Immunity Course
A practical day’s training for those on the front line
Turn your early suspicion on inborn errors of immunityinto action, referrals and better outcomes.
Learn from the Immunodeficiency Experts
Inborn errors of immunity often hide in plain sight: the patient with infections and inflammation that keep coming back, the unusual patterns that don’t quite fit, the case you can’t stop thinking about on the drive home.
On 14 October in Maastricht, leading experts will come educate you for a single, focused day on how to spot, screen and support patients with suspected immunodeficiency. Because the earlier these conditions are recognised, the sooner a diagnosis is made, and the more we can change the course of a patient’s life.
