Milk protein (casein) concentration in serum or plasma

Why Might This Test Be Ordered?

Your healthcare provider may request this test if you have symptoms like unexplained weight changes, kidney issues, or if they suspect a metabolic disorder affecting protein digestion or absorption. It could also be part of a broader evaluation for conditions like milk protein intolerance or certain genetic disorders.

What Does the Test Involve?

A blood sample is taken from a vein in your arm. The sample is then processed to measure the concentration of milk-derived proteins (casein) in your serum or plasma. The result helps determine if protein levels are within expected ranges or if abnormalities exist.

What Are Possible Results?

Results are typically expressed as a concentration value (e.g., grams per liter). While reference ranges vary by lab, abnormal results may indicate conditions such as protein malabsorption, kidney dysfunction, or metabolic disorders.

What Does It Mean If Results Are Abnormal?

Elevated levels might suggest conditions like kidney disease or certain genetic disorders, while very low levels could indicate malabsorption issues or metabolic problems. Your provider will discuss these findings with you based on your clinical context.
