What kind of Dr would you go to for treatment of Primary Humoral Immunodeficiency?

For treatment of Primary Humoral Immunodeficiency (PHI), you would typically consult an immunologist. These specialists are trained to diagnose and manage disorders of the immune system, including PHI. They can provide appropriate treatment options, such as immunoglobulin replacement therapy, and help monitor and manage any associated infections or complications. In some cases, a hematologist may also be involved in the care if there are blood-related issues.
