Complete blood counts and biochemical parameters of the patients were measured.
Complete blood counts were analyzed using a Sysmex XN-10 Automated Hematology
Analyzer (XN series, Sysmex Corporation, Kobe, Japan) according to the
manufacturer’s instructions. Serum procalcitonin levels were measured with a
Unicel-DXI (Beckman Coulter Inc., Brea, CA, USA) using a commercial
chemiluminescence immunoassay test kit (
Access PCT; Beckman Coulter Inc.). 25-OH
vitamin D and parathormone levels were measured using a Beckman Coulter Unicell
DXI 800 immunoassay analyzer (Beckman Coulter Inc.) with commercial
chemiluminescence immunoassay kits supplied or validated by the manufacturer.
Other biochemical parameters were measured using a Beucher Coulter AU 5800
(Beckman Coulter GmbH, Krefeld, Germany) with commercial test kits produced or
validated by the manufacturer.
Serum creatinine, lactate, phosphorus, calcium, and albumin levels were analyzed
using standardized laboratory procedures. Serum procalcitonin levels were
measured using an immunoluminometric assay, and C-reactive protein levels were
measured using nephelometry. Serum parathyroid hormone levels were measured by
immunoradiometric assays, and 25-OH vitamin D levels were measured by
chemiluminescent immunoassay.
