A complete urinalysis evaluates several different aspects of your urine through physical, chemical, and microscopic examination. In lupus treatment, a urinalysis is often used to monitor protein leakage and identify and assess urinary tract infections (UTIs). Most people with kidney lupus (lupus nephritis) will have an abnormal urinalysis. Protein, urine casts (especially red blood cell casts), red blood cells, or white blood cells in the urine can indicate serious kidney involvement; leukocyte esterase may indicate a bladder infection.

Urine samples can be given at any time while at the doctor’s office. A urine culture is performed to assess for a bladder infection and to determine appropriate antibiotics. Before giving a urine sample, ask a medical professional to counsel you on how to prevent contamination. Several analytical elements of the complete urinalysis are explained below.
