What Does This Blood Report Indicate?

Thyroid
Detailed Answer:
I understand you are concerned about your TSH reading. It potentially indicates a mildly under-active thyroid problem called Hypothyroidism.
Whether or not you need thyroid medicine for life, is a complex decision. In order to make this diagnosis accurately as to whether you have a permanently under-active thyroid, a thorough in-person evaluation is required.
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)
TSH (checks your thyroid)
Free T4 (this too checks your thyroid) Thyroid autoantibodies : Anti Thyroid Peroxidase (TPO) antibodies and Anti Thyroglobulin antibodies
25 hydroxy Vitamin D levels (ideal range 40 to 60 ng/ml = 100 to 150 nmol/liter)
None of these tests require any fasting and can be done at any time of the day.
If your thyroid antibodies are positive, it is quite likely you will need your thyroid medication for life.
Your low white blood cell count is unlikely to be connected to the TSH. You need to talk to your primary care provider about further steps regarding this.
