Many hospitals do not test below 0.1 so <0.1 is classed as undetectable. Even the top cancer hospital in Britain, The Royal Marsden, only tests down to 0.04.
Consultants I have spoken to consider super-sensitive assay tests to umpteen decimal points such as you have had to be more trouble than they are worth, and Matron Kierkegaard here reports that women can have PSA levels of 0.6!
Women on average have a PSA level of 0.002.
So keep calm and carry on being cancer free!
Cheers, John.
