How the blood is taken

The tool starts on a vein draw when you pick a hormone or blood-count marker: finger-prick samples can be contaminated by gels and creams and clot more easily, so most providers advise a vein draw for those.

Advanced options

Some labs calculate free testosterone from total testosterone, SHBG and albumin rather than measuring it. With this on, only measured results count.
