Aim. Blood serum and urinary procalcitonin (PCT) concentration in healthy persons was studied. Materials and methods. A single-stage observational study of “case-control” type was performed. The study included 32 men and 37 women of middle age (53.4 ± 16.4 years) with normal renal function. PTC concentration was determined with the method of solid-phase enzyme immunoassay using test-system (Procalcitonin IFA-BEST, Russia). Results. Blood serum PCT concentration in the examined persons was 0.029 ± 0.016 ng/ml ( M ± SD ). The number of blood serum samples with PTC level > 0.05 ng/ml was 5.8 % (4 from 69). The mean urinary PTC concentration by 72.59 times exceeded the mean blood serum PTC content and was 2.12 ± 1.832 ng/ml ( р < 0.1). Coefficient of variation of results for the urine by 1.57 times exceeded the analogous index for the blood serum. When comparing the results of blood serum and urine analyses, no statistically significant differences between men and women were revealed. When estimating the coefficients of linear correlation between PTC content in the blood serum and urine, a weak positive dependence was established ( R = 0.302782). Conclusions. High PTC concentration in the urine permits to suppose that one of the ways of procalcitonin removal from the blood plasma is its elimination by kidneys in unchanged type by means of glomerular filtration.
