What Is a Serum Protein Electrophoresis (SPEP) Test?
A Serum Protein Electrophoresis test is a blood test that separates the proteins in your blood sample by their size, shape, and electrical charge. It measures the levels of different protein groups and helps doctors spot abnormal patterns that may point to an underlying health condition. The test goes by several names, including SPEP test, Protein Electrophoresis, and Serum Electrophoresis. A small blood sample drawn from a vein in your arm is all that is needed.
What Does a Serum Protein Electrophoresis (SPEP) Test Measure?
The SPEP test analyses six key protein fractions in your blood. Each fraction reflects a different set of proteins and provides useful clinical information.
| Protein Fraction | What It Represents |
|---|---|
| Total Protein | The combined level of all proteins in the blood sample |
| Albumin | The most abundant blood protein; helps maintain fluid balance and carries small molecules |
| Alpha-1 Globulin | Includes proteins such as alpha-1-antitrypsin, which is involved in controlling inflammation |
| Alpha-2 Globulin | Contains haptoglobin and other proteins involved in the body's response to injury or infection |
| Beta Globulin | Proteins that help transport substances like iron through the bloodstream |
| Gamma Globulin | Antibodies (immunoglobulins) produced by the immune system to fight infections |
If an abnormal protein called an M-spike is detected, it may indicate a disorder affecting the cells that produce antibodies.
Why Is a Serum Protein Electrophoresis (SPEP) Test Done?
Doctors order the Serum Protein Electrophoresis test when they want to investigate unexplained symptoms or screen for conditions related to abnormal protein production.
Common Symptoms That May Require This Test
Your doctor may suggest this test if you experience any of the following:
- Unexplained fatigue or persistent tiredness
- Bone pain, particularly in the back or chest
- Frequent or recurring infections
- Unexplained weight loss
- Anaemia (a low red blood cell count)
- Numbness or tingling in the hands or feet
- Back pain without a clear cause
Conditions This Test Can Help Detect
The SPEP test can help identify a range of conditions, including:
- Multiple myeloma (a cancer affecting antibody-producing plasma cells in the bone marrow)
- Monoclonal gammopathy of undetermined significance (MGUS), a benign condition involving an abnormal protein
- Waldenström macroglobulinaemia (a rare lymphoma linked to overproduction of a specific antibody)
- Amyloidosis (a condition where abnormal proteins build up in organs)
- Liver or kidney disease
- Autoimmune disorders and chronic inflammatory conditions
- Alpha-1 antitrypsin deficiency (an inherited condition affecting the lungs and liver)
- Immune deficiency syndromes (conditions where the immune system is weakened)
Serum Protein Electrophoresis (SPEP) Test for Chronic Disease Monitoring
The SPEP test plays an important role in monitoring certain blood cancers over time. In conditions such as multiple myeloma, doctors measure the size of the abnormal M-protein fraction to assess how severe the disease is and how well treatment is working. The test is typically repeated at regular intervals, ranging from monthly to quarterly, during active treatment or surveillance.
How to Prepare and What to Expect
Preparing for a Serum Protein Electrophoresis test is straightforward. Here is what you need to know before your appointment.
Do You Need to Fast?
Fasting is generally not required for this test. However, some laboratories may ask you to avoid eating or drinking for 10 to 12 hours beforehand. Always follow the specific instructions given by your doctor or the laboratory.
Practical Tips Before Your Test
Keep these points in mind before your sample collection:
- Tell your doctor about all medications, supplements, and multivitamins you are currently taking, as several can affect results.
- Wear a loose, half-sleeved top for easy access during the blood draw.
- Stay well-hydrated unless your doctor has asked you to fast.
- Inform your doctor about any recent infections or illnesses.
Step-by-Step Procedure
The sample collection process is quick and straightforward:
- A trained phlebotomist cleans the skin on your inner arm with an antiseptic solution.
- A fine needle is used to draw a small blood sample from a vein, usually at the elbow.
- The blood is collected into a special tube that separates the liquid part of your blood (serum) from the blood cells.
- The sample is sent to the laboratory, where it is placed on a special medium and exposed to a gentle electric current.
- The proteins in the sample migrate across the medium at different speeds, forming distinct bands that represent each protein group.
- A pathologist reviews the protein pattern, identifies any abnormalities, and prepares the final report.
Factors That Can Affect Accuracy
Certain factors may alter your results. Be sure to mention any of the following to your doctor:
- Current medications, including corticosteroids, statins, insulin, or oral contraceptives
- Dehydration at the time of the blood draw
- Recent infections or illnesses
- High blood lipid levels
- Iron deficiency anaemia
- Recent treatment with therapeutic monoclonal antibodies (used in some COVID-19 therapies)
Understanding Your Serum Protein Electrophoresis (SPEP) Test Results
Your results show the measured levels of each protein fraction in your blood. A doctor will review these alongside your symptoms and medical history to give you a meaningful interpretation.
| Parameter | Normal Range |
|---|---|
| Total Protein | 6.4 to 8.3 g/dL |
| Albumin | 3.5 to 5.0 g/dL |
| Alpha-1 Globulin | 0.1 to 0.3 g/dL |
| Alpha-2 Globulin | 0.6 to 1.0 g/dL |
| Beta Globulin | 0.7 to 1.2 g/dL |
| Gamma Globulin | 0.7 to 1.6 g/dL |
These ranges are general guidelines. Your doctor will interpret your results based on your age, health history, and other factors. Always consult a qualified healthcare professional for personalised medical advice.
Results During Special Conditions
Some conditions can shift protein levels in predictable ways, which your doctor will account for during interpretation.
Oral contraceptive use and pregnancy can both cause albumin and gamma globulin levels to appear lower than usual, while alpha-1, alpha-2, and beta fractions may read higher.
Iron deficiency anaemia, pregnancy, and oestrogen therapy can cause an increase in beta-1 protein due to higher transferrin levels.
Certain COVID-19 treatments involving therapeutic monoclonal antibodies have been known to produce sustained interference that may resemble an abnormal protein spike.
How to Maintain Healthy Levels
These general wellness habits support balanced protein levels:
- Eat a varied diet with adequate protein from sources such as pulses, dairy, eggs, and lean meats.
- Drink enough water throughout the day to stay well-hydrated.
- Report any persistent symptoms, such as bone pain, unusual fatigue, or recurring infections, to your doctor promptly.

Frequently Asked Questions
The SPEP test is used to screen for and monitor disorders related to abnormal protein production in the blood. It is particularly useful in identifying conditions such as multiple myeloma, MGUS, and immune deficiency states. It is an inexpensive and easy-to-perform screening test that gives doctors a clear picture of your protein profile.
Most laboratories do not order fasting before the Serum Protein Electrophoresis test. Some may ask you to avoid eating for 10 to 12 hours beforehand. Follow your doctor's specific instructions to ensure the most accurate result.
If your Serum Protein Electrophoresis test shows an abnormality, your doctor may order additional tests such as serum immunofixation electrophoresis, serum free light chain analysis, or serum mass spectrometry to confirm and characterise any abnormal protein. Your doctor will guide you on which tests are appropriate based on your specific results.
An M-spike appears on the results graph as a sharp, narrow peak. It forms because the abnormal monoclonal protein cells are identical and carry the same electrical charge, causing them to cluster together during the electrophoresis process. An M-spike is a key indicator that your doctor will investigate further, usually with additional tests.
Yes, several medications can alter protein levels in the blood, including corticosteroids, statins, insulin, and oral contraceptives. Always inform your doctor about every medication and supplement you are taking so that results can be interpreted correctly.
Most people find the blood draw quick and minimally uncomfortable. You may feel nothing at all, or a brief sting when the needle is inserted. The entire procedure typically takes only a few minutes.
