Blood tests can help you confirm a diagnosis of nephrotic syndrome.  The following results would be expected.

• Increased urea nitrogen and creatinine in the blood suggests kidney damage because the kidney is usually responsible for removing these wastes from the blood.
• Hypoproteinemia occurs due to the increased excretion of proteins in the urine.
• Hyperlipidemia occurs because of the increased synthesis of lipids by the liver and a decrease in their catabolism.  In particular, there would be increased triglycerides, cholesterol, phospholipids, and very-low-density lipoproteins.
