Albumin is a protein naturally present in the blood that helps maintain fluid balance in the body and supports circulation. Human albumin used as a medicine is a purified form of this protein, prepared from donated human blood and given as an infusion when the body has low protein levels or needs fluid support. The term human albumin simply means that the product is made from human blood. So, albumin and human albumin in medical use usually refer to the same type of treatment. The main difference you may see in the market is between different brands or manufacturers. These products generally contain the same active ingredient and strength, such as 20% albumin, but they may vary slightly in packaging or manufacturing standards. However, it is very important not to change or buy a different brand without your doctor?s advice. Albumin infusions should be given under medical supervision, and the exact product recommended by the doctor or hospital should be followed to ensure safety and correct treatment.
