When a problem arises, in some cases the samples from that individual can be pulled and tested. What generally happens is:
>Patients with identified issue come in. Blood spots pulled.
>Healthy individuals serving as controls sign-up. Blood spots pulled.
>Both sets are tested (double-blind, anonymized health status) and hopefully something is found.
- refurb 11y agoBut if a patient goes to their doctor with a problem, why not just get a blood sample then. Why send a request to some storage facility to pull a blood samples from years ago?
- tedunangst 11y agoI think what's meant is they need the heel prick today to do the test, but they need a large sample of control subjects to make the test.
