Substance concentration of a protein in serum/plasma (e.g., albumin, globulin, or other proteins) measured by nephelometry

What This Test Measures

This test detects the concentration of specific proteins in your blood, typically using a method called nephelometry. Proteins like albumin, globulins, or others may be measured, depending on the clinical need. The test helps identify imbalances that could indicate conditions such as kidney disease, liver problems, or infections.

Why It’s Done

Your healthcare provider may order this test to monitor protein levels in your blood. This could be for diagnosing conditions like proteinuria (protein in urine), hypoalbuminemia (low albumin), or to assess how well your body is producing or using proteins.

Common Uses

Common reasons include evaluating kidney function, checking for liver disease, monitoring chronic conditions like kidney disease or heart failure, or assessing immune system function. It may also be used in research or specialized diagnostic scenarios.

Sample Collection

A blood sample is drawn from a vein, usually in your arm. The blood is then processed to separate serum or plasma for testing. You may be asked to fast or avoid certain foods before the test, depending on the specific protein being measured.
