Serum/plasma mass concentration of total protein via electrophoresis

This test is done to help your healthcare provider gather important information about your health. It can show how well certain parts of your body are working, help find the cause of symptoms you may be having, guide treatment decisions, and allow your care team to monitor a condition over time. Your provider will explain the specific reason this test is recommended for you.

Your healthcare provider may order this test to check for conditions like malnutrition, kidney disease, liver problems, or fluid imbalances. It can also help monitor treatment effectiveness for certain medical conditions.

Before the test, your healthcare provider will give you specific instructions, and it is important to follow them carefully. You may be asked to avoid eating or drinking for a certain number of hours, stop taking certain medicines temporarily, or avoid some activities. Tell your provider about all medicines, vitamins, and supplements you take, as well as any allergies or medical conditions you have. Arriving on time and asking questions ahead of the visit can help everything go smoothly.

No special preparation is needed, but you may be asked to fast for 8–12 hours if your blood is drawn early in the morning. Wear a comfortable shirt with an easy sleeve for drawing.

What happens during the test depends on the type being done, but most tests are simple and take only a short time. A member of your care team will explain each step before it happens and answer any questions you have. You may need to change into a gown, lie down, or sit still while a sample is collected or a machine takes measurements. If you feel pain or discomfort at any point, let the staff know right away. Most people are able to go home shortly after the test is finished.

A healthcare professional will insert a small needle into a vein in your arm to collect blood. You may feel a slight pinch, but it usually doesn’t cause discomfort. The blood sample is then sent to a lab for analysis.

Your results will be reviewed by a healthcare provider and explained to you, usually within a few days. Results may be described as normal, which means nothing unusual was found, or abnormal, which means something needs a closer look. An abnormal result does not always mean you have a serious condition, and your provider may order additional tests to learn more. Be sure to ask questions about what your results mean and what the next steps are for your care.

Results are expressed in grams per deciliter (g/dL). Lower than expected levels may indicate protein loss (e.g., kidney disease), malnutrition, or excessive fluid loss. Higher levels could suggest dehydration, liver disease, or overproduction of proteins.
