MARTIARENA, Beatriz et al. Reference values of parathyroid hormone and vitamin D Hormone by chemiluminescent automated assay. Rev.MVZ Cordoba [online]. 2015, vol.20, n.2, pp.4572-4580. ISSN 0122-0268.

Objective. Provide reference data for parathyroid hormone 1-84 (PTH 1-84) and 25OH Vitamin D (25OH D) using a new technique. Materials and methods. The hormones were evaluated, in serum, using a third generation automated chemiluminescent method for PTH in a group of 60 adult dogs, clinically healthy, grouped according to age in years in GA: 1 to 5, GB: 6 to 10 and GC:>10. Results. Data expressed as average ± DS were for PTH (pg/ml): 9.3±2.3; 12±6.3; 12.2±3.7; and for 25OH D (ng/ml): 84.2±27.8; 68.2±16.0; 63.6±23.1, respectively. The PTH value was significantly greater (p<0.05) in groups B and C in comparison with A, but no significant differences were observed between GB and GC. The 25OH D concentration was significantly less in GB (p<0.05) and in GC (p<0.01) in comparison with GA, showing no differences between GB and GC. A negative correlation between 25OH D and PTH was found (r= -0.28; p=0.015). Conclusions. Data contributed by this study provide reference values for PTH 1-84 and 25OH D, evaluated using a third generation automated chemiluminescent method for PTH in local dogs. The results will facilitate monitoring diseases that alter the metabolism of calcium and phosphorus in dogs.
