Are my test results in the "ideal" range?
Here they are:
Free T3: 2.7 (2.3-4.2)
Free T4: 1.11 (0.76-1.80)
TSH: 0.59 (0.34-4.82)
My Doctor says they are completely normal and that I probably have a sleep problem or depression. I'm seeing a good endocrinologist on the 26th so I have high hopes for that Dr.
Here are just some of my symptoms:
Brittle/dry hair
dry itchy skin
Inability to tolerate cold
Feeling tired, sluggish, weak.
Memory problems, depression, problems concentrating
Constipation
dry eyes

Free T4: 1.11 (0.76-1.80)

It's worth ruling out anyway. The two antibodies are called thyroid peroxidase antibodies (TPOAb) and thyroglobulin antibodies (TgAb). There are various reasons for hypothyroidism and it may not be your thyroid gland causing the symptoms but something wrong with the pituitary gland or hypothalamus.
Other labs to look at when hypothyroidism is suspect includes rising in the range or outright elevations of liver enzymes, cholesterol, prolactin and lower in the range or outright deficiencies of vitamin D, iron/ferritin, vitamin B12.

As mentioned, you can be healthy outside the optimal range. With your symptoms though it could be that your thyroid isn't functioning optimally. Have you had your thyroid antibodies tested?

"These optimal range values are based on my observation of nearly 5,000 patients and reflect the lab test values that my healthiest patients tended to have, e.g. a professional tennis player with a sprained ankle. Remember that the optimal zone is an approximation and that it is meant to be used as a rough guide. People can feel well outside the optimal range but the chances of feeling well become more remote the further we get from the optimal zone. Note that laboratory techniques for these tests vary and lab values may have a 5-10% margin of error depending on the laboratory used.
Test Lab Low Optimal Range Lab High
TSH 0.5 1.3-1.8 5.0
Free T4 0.8 1.2-1.3 1.8
Free T3 203 320-330 420
Free T3* 2.3 3.2-3.3 4.2
*Some labs divide FT3 results by 100 thus 230 is the same as 2.3, etc."
