Abnormally high or low protein levels in the blood may indicate an underlying medical condition. Low protein levels in the blood can be caused by malnutrition, liver disease, kidney disease, protein loss in the urine, and medications. High protein levels in the blood can be caused by dehydration, multiple myeloma, amyloidosis, and inflammation.
- Albumin: The liver produces albumin, which is the most abundant protein in the blood. Low levels may indicate liver disease, kidney disease, malnutrition, or inflammation.
- Globulin: Globulins are proteins in the blood that are important for immune function, blood clotting, and transport of nutrients. High globulin levels can indicate inflammation, infection, autoimmune disorders, or liver disease. Low globulin can be caused by malnutrition, kidney disease, liver disease, or certain medications.
- Vitamin B12: Vitamin B12 levels in the blood are crucial for maintaining healthy red blood cell production, proper nerve function, and DNA synthesis. It plays a vital role in carrying oxygen throughout the body and supporting overall cell health. Low B12 levels can lead to anemia, fatigue, nerve damage, and cognitive issues.
