Enter the total testosterone (ng/dL) and the total Shbg (nmol/L) into the Calculator. The calculator will evaluate the Testosterone Shbg Ratio. 

Testosterone Shbg Ratio Formula



  • TSHBGR is the Testosterone Shbg Ratio (ng/dL/(nmol/L))
  • T is the total testosterone (ng/dL)
  • SHBG is the total Shbg (nmol/L)

To calculate Testosterone Shbg Ratio, divide the testosterone in ng/dL by the total Shbg in nmol/L.

How to Calculate Testosterone Shbg Ratio?

The following steps outline how to calculate the Testosterone Shbg Ratio.

  1. First, determine the total testosterone (ng/dL). 
  2. Next, determine the total Shbg (nmol/L). 
  3. Next, gather the formula from above = TSHBGR = T / SHBG.
  4. Finally, calculate the Testosterone Shbg Ratio.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total testosterone (ng/dL) = 1.5

total Shbg (nmol/L) = 6.7
