If someone’s PSA is .01 or less it doesn’t need a < sign. That is the exact PSA, there’s no need for them to say well It’s less than that if that is exactly what it is.

The < sign is really only significant if attached to < .1 Which the medical community considers undetectable. Anything less than that doesn’t require a less than sign To be considered undetectable, Because less than that is undetectable, according to medical literature.
