Protein Total and Protein Electrophoresis (SPEP): how to read your results. It measures the amount and pattern of proteins in your blood to help explain inflammation, liver/kidney issues, or abnormal antibodies—order via Vitals Vault with Quest.
Total protein tells you how much protein is circulating in your blood, while protein electrophoresis (often called serum protein electrophoresis, or SPEP) shows how that protein is distributed across major “fractions.” Together, they help you see whether a change is likely from dehydration, inflammation, immune activity, liver production, or kidney/intestinal protein loss. This test is often ordered when you have unexplained fatigue, weight loss, swelling, frequent infections, abnormal liver or kidney labs, or anemia, or when a clinician is checking for abnormal antibody production. It can also be used to monitor known conditions over time. Because the electrophoresis pattern can suggest different next steps, it is most useful when you interpret it alongside your symptoms and related labs rather than trying to self-diagnose from a single number or graph.

It measures the amount and pattern of proteins in your blood to help explain inflammation, liver/kidney issues, or abnormal antibodies—order via Vitals Vault with Quest.
Total protein tells you how much protein is circulating in your blood, while protein electrophoresis (often called serum protein electrophoresis, or SPEP) shows how that protein is distributed across major “fractions.” Together, they help you see whether a change is likely from dehydration, inflammation, immune activity, liver production, or kidney/intestinal protein loss.
This test is often ordered when you have unexplained fatigue, weight loss, swelling, frequent infections, abnormal liver or kidney labs, or anemia, or when a clinician is checking for abnormal antibody production. It can also be used to monitor known conditions over time.
Because the electrophoresis pattern can suggest different next steps, it is most useful when you interpret it alongside your symptoms and related labs rather than trying to self-diagnose from a single number or graph.
You may benefit from this test if you have a persistent, unexplained change in general health and your clinician wants a broad look at protein balance and immune-protein patterns. Common reasons include ongoing fatigue, unintentional weight loss, night sweats, bone pain, recurrent infections, numbness/tingling, or swelling in your legs or around your eyes.
It is also commonly used when other labs raise questions, such as abnormal kidney function, protein in the urine, elevated calcium, unexplained anemia, high or low albumin, or an unusual albumin-to-globulin (A/G) ratio. In these situations, total protein alone cannot tell you which proteins are driving the change, but electrophoresis can.
If you already have a known inflammatory or immune condition, SPEP can help track whether your protein fractions are stable or shifting. When an abnormal band is suspected or found, follow-up testing is typically needed to identify the specific antibody type.
This test supports clinician-directed care by narrowing down likely causes and guiding what to check next, but it does not diagnose a specific disease on its own.
Results are generated by CLIA-certified laboratories using standardized chemistry (total protein) and electrophoresis methods; interpretation should be confirmed with your clinician and follow-up testing when indicated.

Vitals Vault lets you order Protein Total and Protein Electrophoresis without a referral and complete your blood draw through the Quest network. It is a practical option when you want to confirm an abnormal result, build a baseline, or bring clearer data into a clinician visit.
Once your results are in, PocketMD can help you translate the pattern into plain language, generate questions to ask your clinician, and suggest common companion labs that add context (for example, albumin, liver enzymes, kidney markers, CBC, and urine protein testing).
If your result is borderline or your clinician recommends monitoring, you can re-order and trend results over time so you are not relying on a single snapshot.
Your blood contains many proteins with different jobs. The total protein test measures the combined amount of the two main groups: albumin and globulins. Albumin is largely made by your liver and helps maintain fluid balance and transport hormones and medications. Globulins include many immune proteins (antibodies) as well as transport proteins.
Protein electrophoresis (SPEP) goes a step further by separating serum proteins into fractions based on how they move in an electric field. A typical report shows albumin plus globulin fractions such as alpha-1, alpha-2, beta (sometimes split into beta-1 and beta-2), and gamma. The “shape” and relative size of these fractions can suggest whether a change is due to inflammation, immune activation, liver production issues, or protein loss.
SPEP is most informative when you interpret the pattern, not just the total. For example, a normal total protein can still hide an abnormal distribution, and a high total protein can be caused by dehydration or by increased antibodies—two very different situations.
Total protein is the sum. Albumin is one major component, and globulins make up the rest. If albumin is low, total protein may be low even when globulins are high. If globulins are high, total protein may be high even when albumin is normal.
Clinicians often look for broad increases in the gamma region (a polyclonal pattern) versus a narrow, sharp band (a monoclonal pattern, sometimes described as an “M-spike”). They also consider whether albumin is low and whether alpha fractions are elevated, which can occur with acute inflammation.
Low total protein often reflects low albumin, low globulins, or both. This can happen with reduced protein production (for example, significant liver disease), increased protein loss (kidney protein loss or protein-losing enteropathy), or poor intake/absorption in some situations. On SPEP, low gamma globulins can suggest reduced antibody levels, which may correlate with recurrent infections or immune suppression. Your clinician will usually interpret low values alongside albumin, liver enzymes, kidney function, and urine protein testing.
An in-range total protein with a balanced distribution of fractions generally suggests normal protein production and no obvious excess of immune proteins. This does not rule out every condition, but it makes major protein loss or major antibody overproduction less likely. If you are monitoring a known condition, “optimal” often means your pattern is stable compared with prior results. Trend matters, so comparing to your previous SPEP can be more informative than a single test.
High total protein is commonly due to higher globulins, higher albumin from dehydration, or both. A broad rise in the gamma region can occur with chronic inflammation, infection, or autoimmune activity. A narrow spike or distinct band can suggest a monoclonal protein, which typically prompts confirmatory testing such as immunofixation and serum free light chains, and sometimes urine studies. Because the implications vary widely, the electrophoresis pattern and your clinical context are essential.
Hydration status can concentrate or dilute proteins and change total protein without changing the underlying biology. Recent illness, inflammation, pregnancy, and some medications can shift fractions, especially alpha and gamma regions. Liver function affects albumin production, while kidney disease can lower albumin and sometimes alter other fractions through protein loss. If you recently received IV fluids, had significant vomiting/diarrhea, or were acutely ill, your clinician may recommend repeating the test when you are stable.
Fasting is usually not required for total protein or serum protein electrophoresis. If your order is bundled with other labs (like lipids or glucose), fasting instructions may apply to those tests. Follow the instructions on your lab order.
An M-spike (monoclonal spike) is a narrow, sharp increase in a specific region of the electrophoresis graph that can indicate a single clone of antibody protein. It is not a diagnosis by itself; clinicians typically confirm and type it with immunofixation and may add serum free light chains and urine testing.
SPEP shows the overall pattern and whether there appears to be an abnormal band or spike. Immunofixation is a follow-up test that identifies the type of immunoglobulin (for example, IgG, IgA, IgM) and light chain (kappa or lambda) if a monoclonal protein is present.
Yes. Dehydration can concentrate proteins in your blood, raising total protein and sometimes albumin without a true increase in protein production. If dehydration is suspected, repeating the test when you are well-hydrated can help clarify whether the elevation persists.
Total protein is a sum, so a higher globulin level can be offset by a lower albumin level and still land in the “normal” total range. That is one reason SPEP and related markers (albumin, A/G ratio) can be helpful—distribution can be abnormal even when the total looks fine.
Retesting depends on why it was ordered and what was found. If your result was affected by an acute illness or hydration changes, your clinician may repeat it after you are stable. If a monoclonal protein is suspected or confirmed, the monitoring interval is individualized and often paired with additional tests.

Blood glucose shows the amount of sugar in your blood at a single moment. A1c (hemoglobin A1c) estimates your average blood sugar over roughly the past 8–12 weeks. Comparing them helps explain whether your long-term average lines up with your fasting glucose on draw day.
It helps you understand how this marker fits into your broader metabolic picture, with results tracked in your Vitals Vault account.
Elevated values can signal higher metabolic risk. Many people start with nutrition, activity, sleep, and weight management, then retest and review results with a clinician. This test is educational and does not replace medical advice or diagnosis.
Your sample is processed at CLIA-certified Quest Diagnostics laboratories. Results should still be interpreted with a qualified clinician alongside your history, symptoms, and other labs.
