Activity: Homeostatic Imbalances of Thyroid Function
Name: Theresa Nichole McDaris
Instructor: Adrea Kelley
Date: 08.13.2021
Predictions
1. TSH levels in patients with primary hypothyroidism are
low
2. Thyroxine (T4) levels in patients with primary hypothyroidism are
low
3. TSH levels in patients with secondary hypothyroidism are
low
4. Thyroxine (T4) levels in patients with secondary hypothyroidism are
low
5. TSH levels in patients with hyperthyroidism are
high
6. Thyroxine (T4) levels in patients with hyperthyroidism are
high
Materials and Methods
1. Dependent Variable
blood levels of TSH and thyroxine and accumulation of radioactive iodine in thyroid
2. Independent Variable
thyroid activity
3. Controlled Variables
gender, age
4. Why was RIA used to measure Thyroxine while IRMA was used to measure TSH?
5. How was it used to observe relative amount of iodine accumulated by thyroid gland?

1. The normal range for total amount of Thyroxine in serum is 0.05 - 0.14 mg/L. For each patient, type in their serum Thyroxine
concentration and indicate if it is lower, within, or higher than the normal range.
