Total Protein — What It Means in Your Blood Test
New to reading lab reports? Start with our guide to reading a blood test report
Total protein measures the main proteins in your blood and helps show your nutrition and liver health.
Total Protein rolls two big families of blood proteins into a single number. That combined figure offers a broad sense of how your body is holding together day to day.
Also known as: TP, Serum Total Protein, Total Serum Protein
This isn't a case where higher or lower is better. Your body keeps it in a narrow band, and both directions can matter.

What is Total Protein?
This adds up albumin and globulin, the two protein groups circulating in your blood. Albumin is made by the liver, while globulins include antibodies and transport proteins.
Why is Total Protein tested?
You have this test to check your overall nutrition and how well your liver makes proteins.
What is a normal Total Protein range?
- India
- No India-specific national reference interval is published for this parameter; your lab's printed range is the most reliable comparison.
- Global
- 6.0–8.3 g/dL
Ranges vary by lab, method and equipment — the range printed on your own report is the one that applies to your result.

What does your Total Protein value mean?
There is no widely-accepted set of value bands for this parameter. Compare your result with the reference range printed on your own report, and discuss it with your doctor.
What does a high Total Protein result mean?
A high level can reflect more globulin proteins or too little body fluid. It is worth discussing with your doctor.
What does a low Total Protein result mean?
A low level can mean your liver is making fewer proteins, or you are not getting enough protein in food.
What can affect your Total Protein result?
- Nutrition
- Hydration
- Liver protein making
- Immune activity
- Your posture during the blood draw
