> Is it to the price level (e.g. under $1K) where an individual patient could pay a lab to sequence their own virus sample?

Sure. It'll run under $50 in bulk. Less, but not that much less, if you're only interested in sequencing the spike.

> How about the cost of sequencing one drop of the vaccine vial they received, as a quality control sample of the distribution supply chain?

This isn't a useful quality check. A negative result implicates your field assay rather than manufacturing.

Thanks for the pricing.

What if there were multiple samples of the same lot number, collected in different geographical regions at different times?
