Total Protein with Albumin/GLOBulin Separation (Serum)

Published: August 9, 2026Updated: August 16, 2026

This test measures your blood’s total protein levels and breaks down the protein components—albumin and globulins—into separate parts. Proteins are vital for transporting nutrients, maintaining fluid balance, and supporting immune function.

Why This Test Matters

Your body produces proteins in different forms, each serving unique roles. Albumin, the most abundant protein, helps keep fluids in your blood vessels and carries important substances like hormones and vitamins. Globulins include antibodies (for immunity), clotting factors, and other proteins that help fight infections and support immune responses. Together, these proteins contribute to overall health and disease prevention.

How the Test Works

A small blood sample is drawn and sent to a lab. The serum is analyzed using a specialized method to separate and measure albumin and globulin levels. This helps identify imbalances that may signal underlying health issues.

Common Conditions Affecting Protein Levels

Low total protein or abnormal albumin/globulin ratios can signal conditions such as malnutrition, liver disease (reduced albumin), chronic infections (increased globulins), or kidney disease (protein loss in urine). High globulin levels may indicate autoimmune disorders or chronic inflammation.

What to Expect Before the Test

No special preparation is needed, but inform your healthcare provider about any medications, recent illnesses, or conditions that might affect protein levels (e.g., kidney disease, liver issues, or infections). Avoid heavy meals 2 hours before the draw.

Frequently asked questions

Will my results affect my diet or treatment?
If your test results show abnormal protein levels, your doctor may recommend dietary changes (e.g., increased protein intake for malnutrition), further testing (like kidney function tests), or treatments for underlying conditions (e.g., medications for liver disease). Follow their guidance closely.
Can I fast before this test?
No fasting is required for this test, but avoid heavy meals or alcohol 2 hours before your blood draw to ensure accurate results. Hydration is fine unless your doctor advises otherwise.
What if I have a history of bleeding or clotting issues?
If you have bleeding disorders or take blood thinners, let your lab technician know. They may use a different blood collection method (e.g., a special tube) to prevent clotting artifacts. Your doctor may also adjust your medication timing if needed.
