Thyrotoxicosis was defined as an elevated fT4 and/or free tri-iodothyronine (fT3) concentration, above the upper limit of the local reference range, together with suppressed TSH levels, below the lower limit of the local reference range.
Delayed feed and water access might had induced more dehydration and lower tri-iodothyronine levels in early hatchers of control FR treatment (Careghi et al., 2005) ultimately impaired cell hyperplasia particularly during the first week after hatching which is critical growth stage (Gonzales et al., 2003).
Objective: To determine the reference values for thyroid stimulating hormone, free tetra-iodothyronine and total tri-iodothyronine for healthy pregnant women.
Immune-related AEs occurred in 13 patients and included hypothyroidism, decreased tri-iodothyronine, hyperthyroidism, pneumonitis, pyrexia, and rash.
Detailed history was recorded on a questionnaire, blood samples were collected and serum total tri-iodothyronine (T3), free thyroxine (T4), thyroid stimulating hormone (TSH) and uric acid levels were measured.
The analysis of thyroid stimulating hormone (TSH), thyroxine [T.sub.4] ([T.sub.4]) and tri-Iodothyronine [T.sub.3] hormone ([T.sub.3]) were done by using enzyme linked fluorescence assay (ELISA) technique.
Two such groups are patients with more symptoms (although volunteering for the study suggested dissatisfaction with symptom control) and patients with low tri-iodothyronine (T3) levels (although about half of patients had low baseline levels).
The laboratory investigations revealed hypercalcemia with a corrected calcium of 3.9 mmol/l (2.15-2.50) and hyperthyroidism (Thyroid-stimulating hormone (TSH) 0.23 IU/ml (0.35-4.94), Thyroxine (T4) 20 pmol/l (9-19), Tri-iodothyronine (T3) 6 pmol/l (2.6-5.7).

Hypothyroidism is associated with decreased concentrations of tri-iodothyronine ([T.sub.3]), thyroxin ([T.sub.4]) and increased level of thyroid stimulating hormone (TSH).Thyroid abnormalities (hyperthyroidism and hypothyroidism) are accompanied by changes in intermediary metabolism leading to alterations in body weight, insulin resistance and plasma lipid profile in humans (Heimberg et al., 1985; Pucci et al., 2000) and dogs (Dixon et al, 2002; Hofer-Inteeworn et al, 2012).
[3] Biochemical decrease in T3 (tri-iodothyronine) and T4 (tetra-iodothyronine) concentrations leads to hypersecretion of thyroid stimulating hormone (TSH) from the pituitary causing an increase in the serum TSH levels.
