Effect Of Room Arrangement And Blood Sample Collection Sequence On Serum Thyroid Hormone And Cortisol Concentrations In Cynomolgus Macaques (Macacafascicularis), Bryan L. Flow, John T. Jaques

Research Methodology and Laboratory Animals Collection

We evaluated the relationship, in cynomolgus macaques (Macacafascicularis), between rank for order of blood collection with serum concentrations of 3,5,3'-triiodothyronine (T3), thyroxine (T4), free thyroxine (FT4), and serum cortisol. These relationships were determined for males and females that were housed in two room arrangements. For both room arrangements, males and females were housed separately. For room arrangement 1, macaques were housed on both sides of the animal holding room. The sides of the animal holding room were designated as side A or side B. Blood was initially collected from animals on side A, then from animals on side B. Animals …
