Do I only need to take blood once for multiple tests?

Question from Bas: I would like to order some blood tests from you.
It involves a thyroid test, cortisol measurement and testosterone measurement.
I was wondering whether this can be done with one shot or that, given the amount of blood to be taken, it would be necessary to take several shots spread over several days.
Thank you in advance for your response.

Answer: No, several tests can be done from one tube of blood, if one is pricked the tubes automatically fill up.
You don't notice the blood loss of a few tens of ml.
With blood donors, it's about half a liter at a time, which is much, much more.
