Ed,
I've had some of these, but my TSH levels are high from radiation, indicating hypothyroidism, causing coldness as one of the symptoms, but when the TSH levels are low, it can be hyperthyroidism, caused by a number of factors, but secondary hypothyroidism can occur too from radiation when TSH levels are low, maybe more to do with the pituitary gland, so maybe you may want to clarify that.
My vitamin D, which is actually not a vitamin, I still call it so, is low sometimes. It's from not being in the sun too much in my case, diet, and from CKD, since I believe it's released by the kidneys. Occasionally. I had to take prescription dose vitamin D or D3, 50,000 units a few days, then I take or supposed to take 1,000 units OTC D3 daily. They say above 5,000 units a day should be monitored by blood work to help prevent toxicity buildup, which may be difficult, so I heard.
I have had low vitamin B12, not high, which can cause hair loss. When mine was low I injected myself with B12 I was prescribed. I'm borderline now, and has something to do with RBC production, which is sometimes low, but my hemoglobin is consistently low. High B12 can indicate other conditions or mean nothing, so maybe you want to look into that also.
As far as testosterone, they have oral pills, gels, and injectables to help. I was taking some, but after a recurrence in 2012, I didn't want to take them anymore, not that it can cause cancer, but incase I still had microscopic cancer and cause it to enlarge and or grow at a faster rate. Low testosterone has their own health conditions too.
I see a nephrologist, oncologist/hematologist, besides others, and between them my blood work is being monitored and treated, often with 18-25 out of range areas, but are only concerned with a few or when there is sudden change, but say I'm doing good. They also test the T3 and T4 levels, which can help in diagnoses and confirmation of certain conditions, like thyroid. I stopped seeing an endocrinologist for diabetes years ago since the doctor often had a 6 hour wait, but that's another specialist some may see.
Good luck
