Predictions
TSH levels in patients with primary hypothyroidism are high Thyroxine (T4) levels in patients with primary hypothyroidism are high TSH levels in patients with secondary hypothyroidism are low Thyroxine (T4) levels in patients with secondary hypothyroidism are low TSH levels in patients with hyperthyroidism are high Thyroxine (T4) levels in patients with hyperthyroidism are normal

Materials and Methods
1. Name the Dependent Variable. blood levels of TSH and thyroxine and accumulation of radioactive iodine in thyroid 2. Name the Independent Variable. thyroid activity 3. Name the Controlled Variables. gender, age 4. Why was RIA used to measure Thyroxine while IRMA was used to measure TSH? RIA is used to measure Thyroxine T3 while IRMA was used to measure TSH because T4. 5. How was it used to observe relative amount of iodine accumulated by thyroid gland? It is used by telling whether they have low or normal iodine.

Results
Table 2. Concentration of Thyroxine and Thyroid Stimulating Hormone (TSH) in Blood Serum
Normal Thyroxine (mg/l) TSH (mIU/l) Type of thyroid disorder 0.05-0.14 0.35-4.5 Value 0.23 0.07 Patient 1 Status High Low Hyperthyroidism Value 0.01 9.74 Patient 2 Status Low High Primary Hypothyroidism Value 0.02 0.18 Patient 3 Status Low Low Secondary Hypothyroidism

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. a. Patient with primary hypothyroidism Patient 2 t4 is 0.01 and its concentration is low.
