Several diseases and conditions can be associated with high globulin levels. These include chronic inflammatory conditions like rheumatoid arthritis, autoimmune disorders, certain cancers (lymphoma, multiple myeloma), liver diseases (cirrhosis, hepatitis), kidney disorders, and certain infections. However, it is important to note that high globulin levels alone do not provide a definitive diagnosis but rather indicate the need for further evaluation to determine the underlying cause accurately. Consulting a healthcare professional is essential for accurate diagnosis and appropriate management.
