What is IVIG?

IVIG is an acronym is an acronym for Intravenous Immunoglobulin. It is a medical procedure where a concentrated concentration of the immunoglobulins (antibodies) that are derived from the blood of healthy donor donors are injected directly into the bloodstream of a person through an intravenous infusion.

IVIG can be used to improve the immune system and to treat autoimmune diseases such as immunodeficiency disease, and other diseases. It assists in providing patients with higher levels of antibodies that improve their capability to fight off infections and regulate the immune system’s activities.

What is SCIG?

SCIG is the abbreviation for Subcutaneous Immunoglobulin. It is a medical procedure that involves the use of immunoglobulins (antibodies) collected by healthy donor donors can be injected into the subcutaneous tissues of a patient usually via a subcutaneous injection.

SCIG is utilized to treat a variety of ailments, particularly immune deficiency illnesses, by providing the patient with a constant and constant amount of antibodies to boost their immune system.

In contrast to IVIG which is administered intravenously, SCIG can be administered by self-administration, or caregiver-assisted treatment and is generally administered regularly, usually weekly or biweekly, making it a suitable option for certain patients.
