Thyroxine; Tetraiodothyronine (T4) (5.0 - 12.0 mcg/dL)
Measured by a Thyroxine (T4) radioimmunoassay.
Elevations
- Found in hyperthyroidism, reflecting the overproduction of thyroid hormones.
Thyroid-Stimulating Hormone; Thyrotropin (TSH) (0.5 - 1.5 mU/L)
Measured by a TSH assay.
Depressions
- Decreased in cases of hyperthyroidism as the hypothalamus attempts to regulate excessive thyroid hormones.
Triiodothyronine (T3) (80 - 230 ng/dL)
Measured by a Triiodothyronine (T3) radioimmunoassay.
Elevations
- Found in hyperthyroidism, reflecting the overproduction of thyroid hormones.
Serum Glutamic Pyruvic Transaminase (SGPT)
Urine Specific Gravity (1.005 - 1.030 kg/m³)
Measurement of the concentration of solutes in urine. A lower specific gravity is representative of urine with less solutes and vice versa.
Depressions
- (<1.004) Diabetes Insipidus, a lack of urine concentration due to inadequate ADH.
- May be a result of a transsphenoidal hypophysectomy for management of hyperpituitarism.
