Thyroid Thyroid Function Testing!

A 32-year-old woman comes to your clinic complaining of palpitations for nearly the past two weeks. She has no significant past medical history. You also learn that she has heat intolerance and fatigue. Your physical examination is noncontributory.
Being perplexed, you order a battery of tests. She calls you in three days for the results. The lab results are as follows:
CMP WNL
TI 4 13.0 mcg/dl (4.6-11.2)
TSH pending (4.5-5.0 mUll).

Which other lab test do you wish you had ordered?
A. Free thyroxine index
B. Total T3
C. Thyroid stimulating immunoglobulins
O. Urine pregnancy test
E. Anti-TPO antibodies

Answer D Urine pregnancy test. Since we have taken TSH and T4, that's enough for telling us about the thyroid. Now we perhaps need pregnancy test to decide further for the patient.
