Blood Chemistry Tests
Multiple myeloma blood chemistry tests aid in the diagnosis of multiple myeloma. Multiple myeloma blood chemistry testing typically evaluates kidney function as well as chemical levels in the blood.
Blood urea nitrogen (BUN) and creatinine (Cr) levels are observed to analyze kidney function. High amounts of blood urea nitrogen or creatinine indicate that kidney function is impaired, which is a common symptom of multiple myeloma.
Chemicals analyzed in the blood include albumin or calcium. Albumin is a protein found in the blood, and low levels suggest that a patient’s myeloma is more advanced. Multiple myeloma can also cause calcium levels in the blood to spike. Typical side effects of high calcium include severe fatigue, weakness, or confusion. Lastly, abnormal levels of certain electrolytes such as sodium or potassium may also indicate the patient has multiple myeloma.
