What is the reference range for total protein (TP) in plasma?

Explanation:
Total protein in plasma represents the sum of albumin and globulins in the blood. In a healthy adult, this concentration typically falls within about 60–80 g/L, which corresponds to 6–8 g/dL. That makes the 60–80 g/L range the standard reference interval used by most clinical labs. Knowing the unit conversion helps: 1 g/dL equals 10 g/L, so 6–8 g/dL is 60–80 g/L. Values far outside this range point to issues like malnutrition or liver/kidney problems (lower end) or dehydration and other conditions that raise concentration (higher end). Thus, 60–80 g/L best fits the normal reference range.
