WebWhat is corrected phenytoin level? Corrected phenytoin levels were calculated using the Sheiner-Tozer equation. Corrected phenytoin levels = Measured total phenytoin (micromol/l) [ (albumin g/1 x 0.9)+ 0.1] 40. Results: At Visit 1, mean serum albumin levels were 44.1 +/- 1.1 micromol/l and mean serum phenytoin levels were 33.9 +/- 2.8 g/l. WebThe equation below gives an albumin corrected total phenytoin concentration, which can be compared with the target concentration range (10–20mg/L). Corrected phenytoin concentration = Measured phenytoin concentration (0.9 x Albumin (g/L) / 42*) + 0.1 *Midpoint of reference range for serum albumin.
