I don't think running diagnostics on a human should be this hard, we run diagnostics on our apps, computers, cars more often than ourselves. I wonder if people are working on making this process a lot easier (or if it's even possible, I have zero knowledge of the space).
Here are a few alternatives you can look into, mentioned in this discussion: https://news.ycombinator.com/item?id=15868143

(I also dislike the limitations as I feel like people are more capable of helping themselves in a lot of these situations)
Google "LabCorps" near you.
You can walk in and get a basic metabolic panel in about 15 minutes, with results the next day or two, for about $50, without a doctor. I use them for frequent STI testing.
It seems like it’s just tough because you generally need a fair amount of blood for each test. We could lose some of the bureaucracy but it seems hard to get away from human phlebotomists and lab techs.

While toxicity is a serious matter, the actual risk is generally overblown, since it requires truly heroic, sustained doses.
>The evidence is clear that vitamin D toxicity is one of the rarest medical conditions and is typically due to intentional or inadvertent intake of extremely high doses of vitamin D (usually in the range of 50,000-100,000 IU/d for months to years)

The way to know you're ok at your current dosage is to take a blood test, ideally at least twice a year (summer and winter) so you can make sure you're not overdosing.
I haven't had a blood test in many years, so currently I am only on 3000 IU. It's a big difference, in one week I have 21,000 IU and you have 70,000 IU, I am only taking 30% of the dose you are.
Get a blood test!
