A medical report showing blood test results, handwritten notes, and a green sidebar titled 'CHEMICAL PATHOLOGY.' The notes mention a testosterone level of 2.2 nmol/l and comments about being 24 years old at the time of testing, with a concern that the level was abnormal.

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.
