Donating Blood to Get Free Health Data

I"m not sure if this has been brought up before,
But I just created a user name and password on
They have the test results on all my donations I’ve ever made.
While I don’t have hard data to compare these numbers with,
They do seem to correlate with what I recall my weight was at those times.

This seems like a great way to help the community while getting personal data for free.

Is it possible to do this if I weigh 95 lbs?
