To compare both values accurately:
1 ng/dL = 0.0347 nmol/L
So, 287 ng/dL ≈ 9.96 nmol/L
That means:
Previous
testosterone level: ~9.96 nmol/L
Current testosterone level: 2.80 nmol/L
,there is a significant drop in testosterone levels:
From ~9.96 nmol/L to 2.80 nmol/L
This level (2.80 nmol/L) is very low and consistent with symptoms like erectile dysfunction, low libido, and fatigue
Next Steps
Repeat the total
testosterone test, early morning (between 7–10 AM), fasting.
Also check:
Free testosterone
