Serum Protein Electrophoresis 

Serum Protein Electrophoresis (SPEP) is a laboratory test that separates and evaluates the major proteins in blood. It is used to help identify unusual protein changes that may be associated with different health conditions.

Medi Linx Laboratory provides reliable SPEP testing for hospitals, clinics, and healthcare facilities through trusted send-out laboratory services.

About the Test

SPEP separates serum proteins into different groups so they can be studied more clearly. This helps healthcare providers see changes in protein patterns that may be linked to different health conditions.

In clinical practice, SPEP may be used to help evaluate abnormal protein patterns associated with:

• Monoclonal gammopathies (such as MGUS and multiple myeloma)
• Autoimmune and chronic inflammatory diseases
• Chronic Liver diseases
• Poor nutrition or malabsorption
• Unexplained anemia (associated with suspected plasma cell disorders)

Why This Test May Be Needed

Serum Protein Electrophoresis may be requested when a healthcare provider wants to evaluate abnormal protein levels or patterns in the blood.

This test is recommended if you have:

• Severe or persistent fatigue
• Unexplained weight loss
• Persistent bone pain, especially in the back or ribs
• Unexplained anemia
• Abnormal kidney function or signs of kidney disease
• High total protein levels found on routine blood tests

How the Test Works

Serum Protein Electrophoresis (SPEP) uses a serum blood sample performed in a controlled laboratory to measure and separate different proteins. The test separates proteins into distinct fractions—including albumin, alpha-1, alpha-2, beta, and gamma globulins.  Changes in the protein fractions may suggest different health conditions that need further evaluation.

In general, the test follows these steps:

• A healthcare provider collects a blood sample from a vein in the arm
• The sample is placed on a gel or in a specialized testing medium
• A controlled electrical current is applied to separate the proteins
• Proteins move at different speeds based on their type and properties
• A pattern is created that shows the distribution of blood proteins
• The results are reviewed to assess protein levels and patterns

For patient preparation and patient may provide: 

• 8 hours fasting
• Serum Total Protein
• Patient`s abstract or initial diagnosis or clinical correlation

FAQs

What does a serum protein electrophoresis test show?

The test shows the distribution of the major proteins in your blood serum that helps healthcare provider to identify abnormal protein patterns. The results are interpreted together with your symptoms, medical history, and other laboratory tests.

What happens if serum protein is high?

High total serum protein level or abnormal protein patterns on SPEP may be associated with conditions such as infection, inflammation, or bone marrow-related issues. In some cases, it may also be related to dehydration. 

What is an abnormal result in protein electrophoresis?

An abnormal result may show unusual changes in protein patterns, such as increased or, decreased protein levels, or a sharp peak called an “M-spike.” These findings usually need further evaluation by a healthcare provider, as results are interpreted together with other tests and clinical information.
