Question : My TSH level is 8.55 recently from 9 two years ago. T4free is 1.05 & T 3 is 87. Would I need a thyroid pill for this? My Vit D level is 19 2 years ago, but now up to 32 after Vit D supplement daily. Could that have an effect on TSH level?

Brief Answer:
Thyroid

Detailed Answer:
Your vitamin D level is unlikely to affect the thyroid condition. Although there are recent studies to show that TSH in this range is normal for older individuals I would still suggest you consult an endocrinologist in-person. When I see someone like you in my practice, I typically order the following blood tests in addition to a detailed physical examination

CBC (Complete Blood Count, also known as Hemogram; includes Hemoglobin, WBC and Platelet counts)
Electrolytes (Sodium and Potassium in particular)
HbA1c (Glycosylated Hemoglobin = your last 3 months' glucose average). Also known by other names such as GlycoHemoglobin or Glycated Hemoglobin or A1c
Liver function tests (SGOT , SGPT, Albumin, Bilirubin, Alkaline Phosphatase)
Kidney function tests (BUN, Creatinine) Thyroid autoantibodies : Anti Thyroid Peroxidase (TPO) antibodies and Anti Thyroglobulin antibodies
 None of these tests require any fasting and can be done at any time of the day

I have had those tests and elevated level of 206 for cholesterol, glucose 109, and glycoHbg of 5.9. I will ask my doctorfor those thyroid antibodies. Would elevation of those denote I need thyroid pill?
