Serum or plasma mass concentration of total protein

Why It Matters in Your Health

Your body relies on proteins for many vital functions, including keeping fluids in the right places, fighting infections, and helping cells communicate. Blood protein levels can give clues about how well your organs are working, especially your kidneys or liver.

What Could Affect Your Results

Several factors may influence your protein levels, such as diet (high-protein foods like meat, dairy, or legumes), hydration status, chronic illnesses (like kidney disease or liver problems), or certain medications. Recent blood loss, dehydration, or severe infections can also temporarily change results.

Common Conditions Linked to Protein Levels

Low protein levels (hypoproteinemia) might signal kidney disease, liver failure, malnutrition, or conditions where your body loses protein (like severe diarrhea or vomiting). High protein levels could indicate dehydration, certain cancers, or overactive thyroid.

What to Expect During the Test

A simple blood draw is used to collect your serum or plasma. The sample is then analyzed to measure the total protein content. This test is quick and painless, usually done in a lab setting with minimal preparation needed beyond fasting if required by your doctor.
