Texas criteria for monoclonal antibodies that includes black or latinx as a qualifier (high risk ethnic groups) https://macarthurmc.com/north-texas-obgyns-need-to-know-about-monoclonal-antibodies-for-covid-19/
People with healthy levels of vitamin D are less likely to die of COVID. Vitamin D is actually a hormone and supports health in many ways. People with darker skin often have lower levels of vitamin D, as they need more sun exposure than people with lighter skin to produce the same level of vitamin D. In modern life, many people don't spend much time in the sun and need to supplement with D3.
So then why wouldn't you give them out based on a vitamin D test (a less than 5 min pin prick test)? Why choose a less precise metric that just correlates with lower vitamin D?
That would be like performing prostate exams based on if the person has facial hair or not. You'll mostly be right, but will end up checking some women and skipping some men. Do a prostate exam based on if the person has a prostate and give the antibodies based on low vitamin D level, good grief.
(Also I know you are just relaying the reasoning behind this, this is more rhetorical and aimed at the policy makers)
