Double checked the wording your correct, needs 21 days for the virus to clear your system before the antibodies are detectable.
What kind of test is this?
This test looks for the presence of immunoglobulin G (IgG) antibodies to SARS-CoV-2, the virus that causes the COVID-19 illness. Antibodies are produced by the body's immune system during COVID-19 and start to become detectable around 7 days after symptoms start and increase over time. Antibodies can be reliably detected in the majority of people from 14 days after the onset of symptoms. We advise taking the test 21 days after the onset of symptoms. This is because our laboratory has reported a slight increase in the chances of finding detectable antibodies in samples taken between 17 and 21 days after the onset of symptoms. This test helps to establish whether someone has had COVID-19 and is now producing antibodies to the virus. -

Peer review of Ferguson's code behind his model currently going on in Github is savage.
Turns out what was 'open sourced' isnt the original code but a heavily refactored version by Microsoft and Github removing Fortran sections (took some of the best coders in the world a month)

But even after this work, its still buggy as fuck.
The official docs say the output isnt reliable.They recommend you run it multiple times until you get the results you hoped for..
