Values not shown are within the interval of reference and include white blood cell count, red blood cell count, hematocrit, hemoglobin, mean corpuscular volume, biliary acids, alanine aminotransferase, aspartate aminotransferase, gamma glutamyl transferase, triglycerides, amylase, glucose, total bilirubin, phosphorus, albumin, and cholesterol (a, b); value outside of the interval of reference; Wesche 2009 [10]; Quesenberry et al. 2004 [11]; Binder 2011 [12]; ionized calcium value obtained in-house by a sensitive electrode with a gasometer (ABL80Flex Basic, Radiometer, Bronshoj, Denmark). Reference value by Jensen et al. 2013 [13]; tT4 value obtained by enzyme immunoassay. Reference value by Fredholm et al. 2012 [14]; urine test strip (Combur 10 Test UX, Roche Diagnostics, Mannheim, Germany) measured by an automated analyser (Urisys 1100, Roche Diagnostics, Mannheim, Germany).
