My initial blood test results taken soon after diagnosis.
The key hormone figures are for testosterone, LH and FSH.
All these were low for a 24 year old male.
These blood tests were the basis of the diagnosis of Kallmann syndrome.
The levels of the hormones LH and FSH are key to the diagnosis.
The report from the lab even says that the testosterone level was checked because it was so unusual for a 24 year old male.
