Why This Test Might Be Ordered

Your healthcare provider may order this test to check for conditions like kidney disease, liver problems, malnutrition, or dehydration. It can also help diagnose or monitor certain cancers, infections, or autoimmune disorders.

What to Expect Before the Test

No special preparation is needed. You’ll have a small needle inserted into your arm to draw blood. If you’re on blood thinners, let your provider know before the test.

What the Results Mean

Results are compared to a general reference range, but your actual values may vary slightly depending on lab methods. Low protein levels might suggest malnutrition or liver/kidney issues, while high levels could indicate dehydration or certain diseases.

Common Conditions Affecting Results

Protein levels can be affected by diet, chronic illness, or medications. For example, severe kidney disease may reduce protein production, while some medications (like steroids) can increase protein levels.
