Your immunology team will give you contact details which you can use if a problem arises at home; for example, if you think you have an infection and you want advice about delaying immunoglobulin treatment. Some immunology centres offer this service during office hours only. This means you might want to plan your infusions for during the week until you have some confidence. You can also call your immunology centre if you have other concerns that might be to do with immune deficiency.
