Serum Protein Electrophoresis--Nephrotic Pattern
The nephrotic pattern illustrates the long term loss of lower molecular weight proteins (Examples: albumin, IgG) and retention of higher molecular weight proteins (example alpha-2-macroglobulin.) This patient was a 39 year old female with SLE. Her daily total urinary protein loss exceeded 3700 mg. (Normal loss is less that 150 mg/day.)
