Total protein measures all the protein in your blood, mainly albumin and globulins.
- Normal range (adults)
- 6.3–8.2 g/dL (63–82 g/L)
- Sample
- Blood
- Fasting
- Not usually needed
- Also called
- TP, Serum Total Protein, Total Serum Protein, Protein Total
Total Protein normal range
| Group | g/dLConventional units: US, South Asia | g/LSI units: UK, Europe, Australia, international |
|---|---|---|
| Adults | 6.3–8.2 | 63–82 |
Your report may use either unit system; labs in the Gulf often print both. Ranges also vary slightly between laboratories, so the range printed on your own report is the one to go by.
Why is the Total Protein test done?
It is part of the liver function test and gives a picture of nutrition, liver and kidney function and the immune system.
What does a high Total Protein level mean?
A high total protein usually reflects dehydration or a rise in globulins.
Common causes
- Dehydration
- Chronic infection or inflammation
- Liver disease
- Rarely, multiple myeloma
Diet and lifestyle tips
- Drink enough water
- Repeat the test when well hydrated
What does a low Total Protein level mean?
Low total protein may mean poor nutrition, poor absorption, or protein loss through the liver or kidneys.
Common causes
- Malnutrition or very low protein intake
- Liver disease
- Kidney disease (protein lost in urine)
- Gut conditions affecting absorption
Diet and lifestyle tips
- Eat protein at every meal: eggs, chicken, fish, dairy, lentils, beans
- Eat enough calories overall
When should you see a doctor?
Ask your doctor to review it with albumin, globulin and kidney tests.
