What Is Serum Protein Electrophoresis?

Q:
What is SPEP?

A:
SPEP, or serum protein electrophoresis, is a blood test that measures specific proteins (Albumin, Alpha-1, Alpha-2, Beta, and Gamma) in the blood to help identify some disorders.

These disorders include:

  • Anemia
  • Certain autoimmune diseases
  • Diabetes
  • Liver diseases
  • Monoclonal gammopathy of undetermined significance (MGUS)
  • Myeloma or multiple myeloma
  • Poor nutrition or inability to absorb nutrients
  • Primary amyloidosis
  • Thyroid problems
  • Waldenström macroglobulinemia

The reference values are:

  • Albumin: 60% ~ 75%, or 3.6 ~ 5.2 g/dL
  • Alpha-1 (α-1): 1.7% ~ 5%, or 0.1 ~ 0.4 g/dL
  • Alpha-2 (α-2): 6.7% ~ 12.5%, or 0.4 ~ 1.0 g/dL
  • Beta (β): 8.3 % ~ 16.3 %, or 0.5 ~ 1.2 g/dL
  • Gamma (γ): 10.7% ~ 20%, or 0.6 ~ 1.6 g/dL

If you want to know more about this test, please consult your doctor.
