Recently I went to get blood work done after experiencing some lethargy, lack of focus and brain fog. Pretty much everything came back within the normal range except for my LDL and total cholesterol which were slightly elevated but nothing too out of whack (LDL 125, HDL 50, total 207) . My doc said I could easily bring them down to a decent level by being more physically active and doing moderate aerobic exercise 3-4 times a week.
My B12 came back at 791 pg/ml. Folate is 17.5 ng/ml, ferritin 180 ng/ml, iron 75 mcg/dL, vitamin D 40 ng/ml, RBC 5.77, WBC 9250, hct 49.2%, hgb 16.0, HbA1c 5.18, CRP is good, liver and kidney function all normal. Electrolytes are also all within optimal/normal ranges. Mg is a bit on the lower side but still normal. My TSH is also good now. It sits at 2.32 while being all the way up at 4.5 back in Feb. I think main culprit was lack of iodised salt in diet as my antibodies came back negative. Since I started consuming more iodine, tsh has normalised but brain fog and fatigue haven’t lifted. T4 is 17 pmol/L, T3 - 6 pmol/L.
Cortisol am serum - 460 nmol/L.
Based on those readings I think anaemia, adrenal and thyroid problems could almost certainly be ruled out as a potential cause. One test that I didn’t get done though was homocysteine. Would you say I need to get that checked out with my current B12/folate status or would it most likely be a waste of money? Also, are there any other lab tests worth doing? I’m well aware of testosterone/estrogen and plan on scheduling an appointment to test those soon.
Any tips are well appreciated.
