What is the role of a complete metabolic panel (CMP) in diagnosing SLE?

A complete metabolic panel (CMP) plays a crucial role in evaluating various organ functions and metabolic processes, particularly in the context of systemic lupus erythematosus (SLE). One of the primary purposes of a CMP is to assess kidney function and metabolic status. In patients with SLE, kidney involvement can occur in the form of lupus nephritis, which can significantly impact renal function. The CMP provides essential information about blood urea nitrogen (BUN), creatinine levels, and electrolyte balance, helping to identify any underlying renal complications associated with the disease.

Additionally, the CMP measures glucose levels, liver function tests, and electrolyte levels, contributing to a comprehensive understanding of the patient's overall metabolic state. While electrolyte levels are indeed assessed as part of the CMP, the primary focus in the context of SLE diagnosis and monitoring is on kidney function and the overall metabolic health of the patient. This information is vital for guiding treatment decisions and managing complications related to SLE.
