I've just had some blood work done (yesterday), I got quite a lot of stuff tested/calculated i.e.
FSH, PSA, TSH, Free Thyroxine, LH, SHBG, Testosterone, Estradiol, Haemoglobin, HCT, Red Cell Count, MCV, MCH, MCHC, RDW, White Cell Count, Neutrophils, Lymphocytes, Monocytes, Eosinophils, Basophils, ESR, HsCRP, Platelet Count, MPV, Sodium, Potassium, Chloride, Bicarbonate, Urea, Creatinine, Bilirubin, Alkaline Phosphatase, Aspartate Transferase, Alanine Transferase, CK, Gamma GT, Total Protein, Albumin, Globulin, Calcium, Corrected Calcium, Phosphate, Uric Acid, Glucose, Insulin, Iron, T.I.B.C, Transferrin Saturation, Ferritin , Triglycerides, Cholesterol, HDL Cholesterol, LDL Cholesterol, HDL % Of Total, DHT, Free Testosterone, Bioavailable Testosterone.
This extensive list however was not all due to myself wanting to start finasteride, it was actually myself wanting to get a good overall picture of my health from various different angles (liver, kidneys, thyroid, cholesterol etc.), so it worked best for me to get the 'bundle-pack' as above.
Mainly before starting finasteride I wanted to check PSA, Testosterone, DHT, Free Testosterone, Estradiol, FSH, LH, SHBG - and this only spawned from what I had been reading over time about finasteride. In fact the main inspiration for getting any blood work done at all regarding finasteride was the fact that the finasteride tablets I just got prescribed said in the leaflet "It's advised to take a PSA test BEFORE starting treatment with finasteride." - But I guess even that really mainly applies to the older man in his late 40's upwards.
If you have already been on finasteride for a year, I assume with zero side effects, is there much point in getting blood tests done? I suppose the tests would give you a 'on-finasteride baseline'...
