Abstract

<abstract abstract-type="main"> <title> <x xml:space="preserve">Abstract</x> </title> <sec id="jcla21625-sec-0010" sec-type="section"> <title>Background</title> <p>Biological variation (BV) data of analytes have been used to evaluate the significant changes in serial results (reference change value, RCV) of healthy individuals in clinical laboratories. However, BV data of healthy subjects may not be identical to the analytes of patients with ongoing clinical condition. The aim of this study was to calculate intra‐(CVw) (coefficient of variation for intra‐individual BV) and inter‐individual (CVg) BV, index of individuality, and RCV of nine serum analytes of renal posttransplant patients.</p> </sec> <sec id="jcla21625-sec-0020" sec-type="section"> <title>Methods</title> <p>Six serum specimens were obtained in an interval of two months in a one‐year period from 70 transplant patients who had been stable for three years. Each time creatinine, uric acid, urea, sodium, potassium, calcium, inorganic phosphate, total protein, and albumin of these patients were analyzed with an integrated clinical chemistry/immunoassay auto‐analyzer. ANOVA tests were used to calculate the variations. Results were compared with the data of healthy subjects obtained from BV database.</p> </sec> <sec id="jcla21625-sec-0030" sec-type="section"> <title>Results</title> <p>CVw of all nine analytes of the renal transplant patients were higher than the healthy subjects. RCVs of these analytes were calculated as 14.5% for creatinine, 16.5% for urea, 13.7% for urate, 12.57% for albumin, 8.26% for total protein, 3.25% for sodium, 12.81% for potassium, 5.88% for calcium, and 21.57% for inorganic phosphate.</p> </sec> <sec id="jcla21625-sec-0040" sec-type="section"> <title>Conclusion</title> <p>RCV concept for predicting the clinical status in posttransplant population represents an optimization of laboratory reporting and could be a valuable tool for clinical decision.</p> </sec> </abstract>
