Understanding Total Protein: Normal vs Optimal Ranges

?What is Total Protein?

Total protein measures all proteins in the blood, primarily albumin and globulins. It reflects overall nutritional status, liver synthetic function, and immune system activity. The ratio of albumin to globulin (A/G ratio) derived from total protein measurement provides additional diagnostic information.

!Why It Matters

Abnormal total protein levels can indicate liver disease, kidney disease, nutritional deficiencies, or abnormal immunoglobulin production (as in multiple myeloma). Low protein with normal or high globulin may suggest liver disease; high total protein with normal albumin may indicate elevated immunoglobulins from infection or immune conditions.

Reference Ranges

Lab normal ranges may vary between laboratories. Optimal and longevity targets are based on research literature and should be interpreted with your physician.

Symptoms of Imbalance

• Oedema if very low protein
• Often asymptomatic

How to Improve Your Levels

• 1Ensure adequate dietary protein from diverse sources
• 2Address underlying liver or kidney disease
