The authors would like to report an error in the formula describing the correction factor for the protein content in the serum/plasma. The formula is described as “multiply by (1 – (serum protein content, in g/L)] and is currently written on the 5th page of the article, right column text; moreover, on page 6, under Table 3 - Legend.

The corrected formula should be written as “multiply by (1 – (serum protein content, in g/mL)]”.
