Dr John Quote:
"We also now know that urine (and serum, for that matter) DHT levels are not necessarily reflective of actual intracellular 5-AR (which converts T into DHT) activity. The best biomarker for that process is the urine THF/5-allo-THF ratio. Often we see high serum (and therefore urine) DHT levels, but low ratios of metabolites from intracellular conversion. Or the other way around. For this reason, I no longer order a serum DHT level. The urinary DHT is included in the Rhein panel, so we have it to look at anyway."
I will get onto my doc over here to get that test. At the mo he is going by serum DHT.
