Researchers at Leeds Beckett University are inviting people aged 18+ diagnosed with a Primary or Secondary Antibody Deficiency (PAD/SAD) to participate in a remote interview. The interview, which will take approximately 45 minutes will explore your experience of living with PAD/SAD and how the condition impacts your quality of life. Researchers are looking to speak to anyone with an antibody deficiency. The researchers would particularly welcome speaking with patients who have a secondary antibody deficiency or have been diagnosed with PAD or SAD but have not started Immunoglobulin replacement therapy.

The PhD study is being conducted as part of a wider project which aims to develop a questionnaire which will measure the quality of life in adults with PAD and SAD. This is an important project which needs your input so please consider taking part. If you would like further information, please contact Danielle Musson at
