Serum/Plasma Mass Concentration of Serum Protein (General Protein Measurement)

Why This Test Is Done

Doctors may order this test to evaluate conditions affecting protein synthesis, breakdown, or kidney function. It can also help diagnose or monitor diseases like liver disease, malnutrition, or kidney problems. Sometimes, it’s used to check for protein-losing conditions, such as certain types of heart or lung disease.

What to Expect Before the Test

No special preparation is usually needed. You may be asked to fast for a few hours before the test if it’s part of a more complex evaluation, but this is not always the case. Your blood will be drawn from a vein, typically in your arm, and you may feel a brief pinch or slight discomfort.

What the Test Results Mean

Results are compared to standard ranges for healthy adults. Low protein levels may indicate malnutrition, liver or kidney disease, or excessive protein loss. High levels could suggest dehydration, inflammation, or certain medical conditions. Your doctor will interpret the results in the context of your overall health and symptoms.

Common Conditions Monitored

This test is often used to monitor conditions like chronic kidney disease, liver cirrhosis, severe infections, or inflammatory diseases. It may also be part of routine check-ups for people with known protein-related disorders.
